If you want a meaningful improvement to your sound, move your tower speakers away from the wall. Backing them up to the wall is hampering their ability to open up. Ideally you want them about 3’ away from the wall but if that’s not feasible for your space, any distance is better than none but the closer to 3’ the better
It's sad if RealAndy is not spitting sarcasm. The DIY Perks are among the worst DIY speakers (just a money and time pit for mediocre results) on YT alongside Zac's various ones. Those sound deadening panels don't remotely work the way claimed. They absorb poorly for a given volume (the manufacturers tout STC per weight) and not evenly across frequencies. The whole deadened waveguide would still not work even if the panels were better acoustic material like mineral wool or Owens 703. It's bad geometry.
@@aaronb1138 Have you heard them? (I haven't) but why is it woodwork specialist think they can make a speaker just based on volume and an off-the-peg crossover? Crossovers have to be matched to every speaking the system. Active crossovers are better but not ideal unless designed to go with the drivers. Square boxes are always going to be shit no matter what you stuff in them due to the reflections from the different distances from the rear to the reflective surface. A spherical baffle box is much more accurate - no corners. And that looks more like "simulated" Atmos. I don't even want to dig into the psychoacoustics of height and width information. I noticed a difference in digital headphone HRTF when I switched from a game tuned headset to some Beyerdynamics.
I achieved the best faux height bed by running the receiver in the 7.1 configuration, aiming both rear surround speakers up &15 degrees forward. I then measured the distance from the speaker to ceiling and back down to listening position to set distance (13ft) then I set the crossover for these 2 speakers to 150hz (anything lower becomes directional) The result is it sounds like I have speakers installed in the ceiling. I did not even come close to this good of a result using height channel configurations, that dolby reflect setting or auto room calibration.
That's smart. I feel like this video wasn't doing it correctly. No insult intended to the creator, but it felt like someone baked a cookie recipe wrong and then wondered why they didn't taste as good as people said they should. In the end having actual overhead speakers would be the best, but having everything setup properly for bounce speakers is definitely a must.
I REALLY hate the way these glasses are being marketed. You DON'T want a screen that moves with your head. It means that the only way you can see the corners of the screen is purely by moving your eyes - and that's pretty tiring. The ultimate system would be something like a BigScreen Beyond - but with 4k HDR visuals, and as wide an FOV as possible. Also, I don't understand the speakers - surely you'd want to hide the gap at the back with some sort of cover that blends in with the existing design? And, being really picky, I don't see much point of even using a tweeter for Atmos positional sound - I can't imagine it would have the power to throw sound that far - a single cone would have been sufficient.

All the reviews of those xreal devices I've seen tell me it looks more like a desktop computer monitor than a giant cinema screen. And if it WAS as huge as claimed, I'd want more than 1080p
I have them. It's about perspective. If you look at a wall 1 foot away they look like a small monitor. If you look 12 ft away they look like a 200" screen. I also have an actual 100" UST projector screen and if I'm about 8 feet away it will overlap it. It's actually quite sharp because the small screen means the PPI is quite high.

You need Transducers aka Bass Shakers to really get the feeling of a theater at home. Because you are limited in space in a home theater setup, these make a huge difference because you 'feel' it not just hear it.
Audio exciters/transducers are incredible, HT ones should be installed in your sofa cavity, I even have one in my Steam Deck for the most incredible real-time haptic feedback, I can adjust the frequency to get different response types, I have a profile for FPS games that literally feels like real gun recoil, a shotgun can have a serious kick just like real life lol, it's amazing to have, I recommend people install one in all their gamepads too. Edit> I'm actually building a laser pointed light gun with multi axis with several 2 inch bass inducers, it will have so much kickback it should be amazing when finished, I want to use it with the video game "Bodycam", should be a lot of fun.
@@gemininimeg Subs don't go subsonic which is where the real feel it. If you can hear below 20 Hz you're superhuman, but while we can feel frequencies well above that, we can't hear below. But some audio will have it encoded (or it can be electronically created).
1) There’s no positive benefit to setting the baffle back from the front. You may mitigate some reflections with the lining, but dramatically impact the radiation of the sound. 2) For the interior, your sound deadening material is lined with aluminum. That creates its own resonances. That product is good as a sound barrier, not to reduce resonance from the inside. 3) The port interacts with the open space behind it and is designed with an expected distance from the wall. Since you’ve changed the orientation of the original design, you would be better served with a sealed speaker. 5) Why not just build with MDF and then use walnut veneer. At least you would have been able to replace the veneer instead of tossing the completed boxes.
I like that you made them generic speakers first, then set them up at an angle for an alternate use. If you decide to repurpose them later you won't have to change anything.
Tightbond makes a "dark" wood glue that I love using with Walnut. It's dries a dark brown color and unlike regular wood glue which is pretty easy to see with walnut, the dark glue ends up looking more like grain. I really like that about it for walnut because you can really glob it in your joints and have it fill in any gaps you may have from less than perfect passes on the jointer/planer and when it's all said and done you either can't even tell it's a seem of glue or you can but it looks so natural you dont think about it. I highly recommend it!!
the reason games work so well is that they have to render the sound wherever it comes from anyways, and supporting dolby atmos doesnt require a full remaster with an audio technician like it does with movies or music
Most DVDs had 5.1 audio of some sort, some did more with the surround channels than others (example in X-Men, when Charles guides Logan to his office you can hear the “voices” all around you).
Great project! For a good Atmos height experience, I would recommend the Ready Player One race scene from the beginning of the movie. Also in The Force Awakens when Rey meets Finn and they're chased on the Millenium Falcon. Also if you can, since you have a PS5 watch them off of the 4k Blu Ray's. The sound quality is much better than streaming.
I love watching audio enthusiast stuff like this, but for my “home theater” a Sony av box, some decent Bose speakers and a passive subwoofer are more than enough.
Maybe make the speaker in a cylinder like a sound cannon? Make the exit lip an inverted cone so it focuses the sound into a tighter beam? Just a thought. Great video!
This is a pretty niche comment, but if anyone is doing a sewing project and needs stuffing, I don't recommend the polyfiberfill stuff. You wanna look for the more expensive varieties, they have different names but its usually like, "silky" or "luxury", it makes a huuuuge difference in a pillow or stuffed animal.
You should try playing a particular spot in the game where you feel the height is quiet prevalent and the Atmos is doing exactly what you expect.... even play it a couple of times so you know what to "look" for/"listen" for ... THEN disconnect the height speakers ... right at the back of the speaker - NOT disabling them in software.... then play that same part of the game again and see if there is a noticeable difference... This, I feel, is the ONLY WAY to TRULY know how much the reflection off the ceiling is actually doing what you think (it isn't by the way LOL - there is VERY LITTLE actually reflecting.... it's (mostly) all coming from the speakers and them being at an angle and you just perceiving that as being 'above' the typical sound plane.... putting speakers ABOVE YOU is best way to get them to come from above... (or using beam forming speaker tech and a reflective surface like metal and using PRECISE aiming.. but that is a whole other can of worms LOL) BUT like you said, Dolby Atmos isn't about the Height channel coming from ABOVE you but creating height to the things in front of you :) - I am still VERY IMPRESSED with you setup!!!! Those speakers looks AMAZING and I would LOVE to be able to build that same type of setup my self!! I'm a bit jealous bro!!!! But I'll be fine with my 7.2 and PC games in 4K :D
There will be vibration between the speakers on top and the speakers on the bottom. You should have either glued them to each other or put some kind of dampening layers (air or magnetic springs) or spikes in between.
you could make it so that the top speakers clip in to the towers with a ratcheted hinge piece for adjustments so you can have them integrated but still removable
Use pythagoras theorem to get the correct angle for your speakers. the speaker should basically perpendicularly point to the ceiling surface above the primary listening position. This is what really worked for me anyway. The Z axis sounds are extremely accurate and directly above you.
Soundbars can't fully create an authentic separation between channels. My 10 year old M-Audio Studiophile AV 40 paired with a decent subwoofer will outperform most of these ridiculous soundbars trying to act as a surround system. It's better to have quality stereo separation than fake surround sound in my opinion at least.
I would believe if you changed your speaker tilt towards you that you would get more of an overhead sound. For getting a specific directional sound (or more than you got) we'll take a page out of live sound and use square speakers instead of round ones. If you use these and middle the speakers in the cabinet (both tweeter and mid/sub), having the lip that you used with the wood and the added foam will help make the direction of the sound more controllable. If you want to go crazy, if you add more lip and calculate the angles, you can nearly redirect all sound in 1 direction. Kind of like using a parabolic dish, but square. A lot of live sound speakers have the square siren shape where the speakers project because it focuses sound in one direction than in a cone shape like typical speaker cabinets. This is just what I remember from my live sound class in school, tech has probably changed and I could be so wrong :P
Cool Video! A little off-topic, but is it possible to remake/remaster the DIY gaming phone? It still had a lot of potential (might as well try with another device that is more overclockable)
Hey no hate but you need to calibrate your heights as “ TOP MIDDLE” not front heights. It’s not going to feel like it’s above you if they are not coded to do so. Atmos will almost never send information in a two channel atmos system if they are not coded for MIDDLE heights. I have a dedicated theater with 6 height channels and 9 floor speakers and dune is actually one of the most active mixes ever released. I think if you calibrate again you might get a better experience. Keep up the great work, you did a fantastic job!!!
Something really gross about a UA-cam video having an ad, which permeates the entire videos topic vs just a small segment. Without the glasses this entire video may not have even been created at all. Whenever UA-camrs do this, makes it really hard to trust them. Feel like I just got scammed into watching a 20 minute ad, that happened to include a speaker build.
If you are looking for a genuinely overhead sound to really test the effectiveness of those speakers, you might want to watch the first few minutes of the first Star Wars movie which eventually became known as Episode IV - A New Hope. The shot of the two space ships passing overhead ought to do the trick. 😎
Yes, Atmos added to a console will likely work with every single game because the positional audio that Atmos has, has been done in video games for decades, all that is needed is to encode the output in the Atmos format.
There are many reasons to see a film in a theater no matter how good your home theater is from a technical perspective. Primarily, it’s a dedicated environment to experience the film that shuts out distractions and allows you to focus on the story. In addition, there is power in the communal experience, especially for big tent pole films. While this can be a double edged sword, there is value to having the same experience alone together with a room full of strangers.
Very nice speakers! If you turn your head with the glasses and the screen follows.. it'd immediately screw up the positional audio. I would love to try the glasses.. I hear mixed reviews so I want to see myself.
I have to disagree on solder connections being more secure. It may seem like they are more permanent but I think I would rather have a crimp on gold plated physical connection with a bit of conductive grease for the contact. Cold solder joints are a real thing and if you aren't used to soldering, or don't have access to decent flux, or even know what a good soldered joint even looks like then you are better off with mechanical connections.
Oh yeah that too, most Atmos mix makes very little uses of the height channel, cool project but I think 7.1 is more immersive if you don't already have sides, that and tactiles transducers/bass shakers :)
Can I suggest an improvement to the cabinets. First, fix half inch bracing down the centre line of each panel to make them more rigid. Then pour Plaster of Paris in either side, each time with the cabinet on a slope, so as to create an asymmetrical layer at least half an inch thick in each section. But, importantly, poured in so that no inner surfaces are parallel. Then add those acoustic panels on top of the drying Plaster of Paris. You will now have dense, weighty and sound absorbent cabinets.
If you watch The Last of Us, the first episode has a scene where they're driving, and a plane flys overhead. The atmos makes it feel like you're in the car with them as the plane flys bye
@15:26 noticed you setup the speakers as front heights. This could be why when watching movies you are not getting the complete atmos overhead sounds. Id be curious to know if you feel if they sound different by recalibrating using the speakers as Dolby SP for up firing front speakers. There should be a specific Dolby option for up firing front speakers during the speaker setup for Denon Receivers.
So the atmos drivers dont sound correct because of 2 things, power, and angle. You need them to be angled to bounce the sound pretty much 3/4ths of the way from you sitting to the speaker, and you need to run them sorta hot compared to what you might think. Then, there is the problem with it being a 2 way offset design. Most up-firing atmos speakers are full range drivers or concentric because of the narrow angle they need to play in, and the dispersion characteristics of those drivers in the high frequency. Also, they are usually being played ~120hz and up to avoid omnidirectional waves. Just some thoughts to consider!
Toy clearly didn't get it at all, the most important thing of the cinemas is the HUGE screen, for sound surround there are plenty of already made solutions that are great, you're reinventing the wheel unnecesarily here.
Where can you get custom PCBs made for under $2 each, as you mentioned at the end here? (Did you include a link for that anywhere?)(Because you never mentioned the name of the place you found that makes them.)
Couldn't you have just built the directional speakers into the cabinet of the existing speakers you have. The cabinets would have been much smaller and looked a lot less awkward
NGL, I've always just rolled my eyes at augmented and virtual reality. It just felt like another gimmick, like 3d HDTV. Technology that nobody asked for but those glasses really piqued my interest. I'm a home theater buff, I have been since the laser disc days. I have a 7.2 channel Sony str-dn1080 Atmos receiver with Klipsch speakers all the way around, I have a Sony OLED 65" TV and an HTPC I've built into my entertainment stand which has 144tb worth of space and it's filled with games, Hi-Res Audio music, movies and TV and I can totally see these glasses being an extremely worthy addition to my setup. Esp since my receiver has a 2nd output that's can be changed at the press of a button. Now, let's see if I can afford these glasses
when using the dynamat stuff im pretty sure you only need a small portion in the middle of the material (not having to cover the entire area) .. for example a 6 square inch piece on a rear quater panel that is like 3 foot ... this coming from the "old timers" from the audio shop i worked at for many years.. not many people get it installed much these days though cause car manufacturers have their own stuff preinstalled now .. just my 2 cents
You can also buy pre made Car Audio crossovers from most brands.... I have had 3 sets of crossovers along my way and some offer better options than others, you can have + or - 3 db and other options... I used to install car audio all the time and most component speakers have crossovers and people often only use the mid speaker to replace a factory speaker and sell the crossovers.
cool build, however, to get the most out of it, height-channel speakers should be in-celling mounted, the up firing ones will give you some effect but nowhere near celling mounted ones.
I traded a much more expensive guitar amp for a Crown Com-Tech 400 power amp from an AMC Movie theater. It has special AMC branded XLR input and separate passthrough. I Bought it just for the AMC #STONKS It will later power a separate folded horn 18", but for now, the Klipisch Professional line 12" floor monitor (from eBay) The main #JUICE will be the Behringer PMP4000 powered mixer pushing the dual 15" JBL JRX225. This caught my attention because #Movietheater
it will sound garbage and if you think its working then its the tweeter only that's reflecting the sound because high frequency can reflect as they can be focused but the speaker driver produces mid or low frequency which spreads in all directions and is much difficult to focus this side panel will never do much you should use transformer tweeters to focus it well it will do the job .
I remember there was a Visaton paper from the mid 80s which compared all sorts of speaker building materials, using the their then best anechoic chamber in Europe. The winner was... something like i forget concrete bitumen sandwich or something like that. Or was it glass bitumen sandwich. But for practical materials it was MDF. However the conclusion was that you get the same exact outcome out of any wood if you just use an approximately 30% thicker piece. For side pieces, you can also just brace them on an odd angle. For the front, thicker and inherently deader was better. But i also think nobody should really care about how good surround speakers sound, as long as they have vaguely the same character in the midrange and treble as main stereo speakers. Not that they necessarily do here with their cones of shame in the front and being used an indirect source, but... worth an experiment i guess :D Console games lean heavily into object audio APIs, where the game tells the system the position of sound emitters, while the console figures out how to render or output this to a suitable spatial audio. It's less widespread on PC, where some games do that but the majority do internal audio rendering and only support the most standard types of speaker arrays. Outright crimes are common, for example you'd think good spatial audio would be quite important for Apex Legends including height cues, but it entirely lacks HRTF, it just has the crudest panning you might imagine and worse.
My verdict is out... on the idea of optical glasses. Humans weren't designed to focus so close for extended periods, currently there are so studies that support my basis. But the idea is cool! Your production value designing, fabrication, and video audio quality are bar none Love it keep em coming. Thanks
Zac sucks at speakers. Zac chooses form over function. 50W woofer used in build, crap. One off center sub crap. DTS has twice the resolution, which makes sense. Garbage speakers, garbage processing. I would pay money to NOT watch any movies at his house. A pair of 901s would sound better.
Cool project. I find the audio mastering on movies these days pretty annoying though. Conversations sometimes sound like whisper level, then giant explosions that blast your eat drums out. Could you EQ that out with a set up like this? They call it "cinematic mastering" but I think it's trash. lol

It's dries a dark brown color and unlike regular wood glue which is pretty easy to see with walnut, the dark glue ends up looking more like grain. I really like that about it for walnut because you can really glob it in your joints and have it fill in any gaps you may have from less than perfect passes on the jointer/planer and when it's all said and done you either can't even tell it's a seem of glue or you can but it looks so natural you dont think about it. I highly recommend it!!
A project that would compliment the speakers and entertainment area would be a DIY record player build.
More crap to pile up, sure thing.
the reason games work so well is that they have to render the sound wherever it comes from anyways, and supporting dolby atmos doesnt require a full remaster with an audio technician like it does with movies or music
The pokemon movie DVD had Dolby support, when Mewtwo speaks(he speaks psychically) you can hear him from behind and above you.
Most DVDs had 5.1 audio of some sort, some did more with the surround channels than others (example in X-Men, when Charles guides Logan to his office you can hear the “voices” all around you).
I like the air pressure in the movie theatre. There's a feel to being in a large dark room. Slightly cool but not cold.
Well that was a bunch of work for zero reason lol
Hater
I just happened upon your channel and I'm so glad I did! Thanks for going into so much detail about your process.
Love the project, hate that you didn't mirror the front panels 🤣
Great project! For a good Atmos height experience, I would recommend the Ready Player One race scene from the beginning of the movie. Also in The Force Awakens when Rey meets Finn and they're chased on the Millenium Falcon. Also if you can, since you have a PS5 watch them off of the 4k Blu Ray's. The sound quality is much better than streaming.
I love watching audio enthusiast stuff like this, but for my “home theater” a Sony av box, some decent Bose speakers and a passive subwoofer are more than enough.
Maybe make the speaker in a cylinder like a sound cannon? Make the exit lip an inverted cone so it focuses the sound into a tighter beam? Just a thought. Great video!
@19:35 The cat stares at the camera saying "What the Hell this man is doing on my king-size bed? Interrupting my most-needed rest?" 🤣🤣🤣
This is a pretty niche comment, but if anyone is doing a sewing project and needs stuffing, I don't recommend the polyfiberfill stuff. You wanna look for the more expensive varieties, they have different names but its usually like, "silky" or "luxury", it makes a huuuuge difference in a pillow or stuffed animal.
You should try playing a particular spot in the game where you feel the height is quiet prevalent and the Atmos is doing exactly what you expect.... even play it a couple of times so you know what to "look" for/"listen" for ... THEN disconnect the height speakers ... right at the back of the speaker - NOT disabling them in software.... then play that same part of the game again and see if there is a noticeable difference...
This, I feel, is the ONLY WAY to TRULY know how much the reflection off the ceiling is actually doing what you think (it isn't by the way LOL - there is VERY LITTLE actually reflecting.... it's (mostly) all coming from the speakers and them being at an angle and you just perceiving that as being 'above' the typical sound plane.... putting speakers ABOVE YOU is best way to get them to come from above... (or using beam forming speaker tech and a reflective surface like metal and using PRECISE aiming.. but that is a whole other can of worms LOL) BUT like you said, Dolby Atmos isn't about the Height channel coming from ABOVE you but creating height to the things in front of you :)
- I am still VERY IMPRESSED with you setup!!!! Those speakers looks AMAZING and I would LOVE to be able to build that same type of setup my self!! I'm a bit jealous bro!!!! But I'll be fine with my 7.2 and PC games in 4K :D
There will be vibration between the speakers on top and the speakers on the bottom. You should have either glued them to each other or put some kind of dampening layers (air or magnetic springs) or spikes in between.
I think new floor speakers in the future would be a cool build that incorporate the top firing speakers for the Atmos!!
Love your Projects !!!
Big Fan from your Videos
What microphone do you use? It sounds awesome always
Can't wait for the Walnut modified AR glasses 🕶️ 🤓 😂
you could make it so that the top speakers clip in to the towers with a ratcheted hinge piece for adjustments so you can have them integrated but still removable
Use pythagoras theorem to get the correct angle for your speakers. the speaker should basically perpendicularly point to the ceiling surface above the primary listening position. This is what really worked for me anyway. The Z axis sounds are extremely accurate and directly above you.
Real speakers in the actual locations are always better. Fake surround is not as good, even with those £800+ soundbars.
Soundbars can't fully create an authentic separation between channels. My 10 year old M-Audio Studiophile AV 40 paired with a decent subwoofer will outperform most of these ridiculous soundbars trying to act as a surround system. It's better to have quality stereo separation than fake surround sound in my opinion at least.
I would believe if you changed your speaker tilt towards you that you would get more of an overhead sound. For getting a specific directional sound (or more than you got) we'll take a page out of live sound and use square speakers instead of round ones. If you use these and middle the speakers in the cabinet (both tweeter and mid/sub), having the lip that you used with the wood and the added foam will help make the direction of the sound more controllable. If you want to go crazy, if you add more lip and calculate the angles, you can nearly redirect all sound in 1 direction. Kind of like using a parabolic dish, but square. A lot of live sound speakers have the square siren shape where the speakers project because it focuses sound in one direction than in a cone shape like typical speaker cabinets. This is just what I remember from my live sound class in school, tech has probably changed and I could be so wrong :P
Okay so the speakers are are cool and whatever... But what I really need more of is that cat. Good lord she's stunning and should be in every video.
Cool Video! A little off-topic, but is it possible to remake/remaster the DIY gaming phone? It still had a lot of potential (might as well try with another device that is more overclockable)
Hey no hate but you need to calibrate your heights as “ TOP MIDDLE” not front heights. It’s not going to feel like it’s above you if they are not coded to do so. Atmos will almost never send information in a two channel atmos system if they are not coded for MIDDLE heights.
I have a dedicated theater with 6 height channels and 9 floor speakers and dune is actually one of the most active mixes ever released.
I think if you calibrate again you might get a better experience. Keep up the great work, you did a fantastic job!!!
Glad I waited to comment, the whole time I was thinking, "Man, that baffle is WAY to far back!" lol
Well that was a waste of time lol
True, as soon as the fucking goofy glasses came out I came to the same conclusion.
yeah
Something really gross about a UA-cam video having an ad, which permeates the entire videos topic vs just a small segment. Without the glasses this entire video may not have even been created at all.
Whenever UA-camrs do this, makes it really hard to trust them. Feel like I just got scammed into watching a 20 minute ad, that happened to include a speaker build.
Plus the ones he linked are 120"
Not 300"+
@@Sr.DudeGuy that's not true. You can expand up to a virtual 300" screen with the Nebula app or Beam.
If you are looking for a genuinely overhead sound to really test the effectiveness of those speakers, you might want to watch the first few minutes of the first Star Wars movie which eventually became known as Episode IV - A New Hope. The shot of the two space ships passing overhead ought to do the trick. 😎
A case for theaters is that movies are show in their original intended form, while digital release are compressed and color is often altered.
Yes, Atmos added to a console will likely work with every single game because the positional audio that Atmos has, has been done in video games for decades, all that is needed is to encode the output in the Atmos format.
Thank you for the super video! Keep the good job! :)
There are many reasons to see a film in a theater no matter how good your home theater is from a technical perspective. Primarily, it’s a dedicated environment to experience the film that shuts out distractions and allows you to focus on the story. In addition, there is power in the communal experience, especially for big tent pole films. While this can be a double edged sword, there is value to having the same experience alone together with a room full of strangers.
The angle brackets were interesting but I would've made high heels for the speakers instead. Though your solution us great for fine tuning
For me finding dolby atmos processor (or atmos receiver with a lot of channels) for a affordable price is a main issue
When he said "why don't I just explain this over the voiceover, fuck it", I felt that.
Very nice speakers! If you turn your head with the glasses and the screen follows.. it'd immediately screw up the positional audio. I would love to try the glasses.. I hear mixed reviews so I want to see myself.
I have to disagree on solder connections being more secure. It may seem like they are more permanent but I think I would rather have a crimp on gold plated physical connection with a bit of conductive grease for the contact. Cold solder joints are a real thing and if you aren't used to soldering, or don't have access to decent flux, or even know what a good soldered joint even looks like then you are better off with mechanical connections.
Oh yeah that too, most Atmos mix makes very little uses of the height channel, cool project but I think 7.1 is more immersive if you don't already have sides, that and tactiles transducers/bass shakers :)
Can I suggest an improvement to the cabinets.
First, fix half inch bracing down the centre line of each panel to make them more rigid.
Then pour Plaster of Paris in either side, each time with the cabinet on a slope, so as to create an asymmetrical layer at least half an inch thick in each section. But, importantly, poured in so that no inner surfaces are parallel.
Then add those acoustic panels on top of the drying Plaster of Paris.
You will now have dense, weighty and sound absorbent cabinets.
If you watch The Last of Us, the first episode has a scene where they're driving, and a plane flys overhead. The atmos makes it feel like you're in the car with them as the plane flys bye
For someone like me it's not a pain in the ass to mount speakers everywhere In fact I enjoy that stuff. What a baby😂
@15:26 noticed you setup the speakers as front heights. This could be why when watching movies you are not getting the complete atmos overhead sounds.
Id be curious to know if you feel if they sound different by recalibrating using the speakers as Dolby SP for up firing front speakers. There should be a specific Dolby option for up firing front speakers during the speaker setup for Denon Receivers.
Going to a movie theater is about a corporate experience, not just a good sound system.
So the atmos drivers dont sound correct because of 2 things, power, and angle. You need them to be angled to bounce the sound pretty much 3/4ths of the way from you sitting to the speaker, and you need to run them sorta hot compared to what you might think. Then, there is the problem with it being a 2 way offset design. Most up-firing atmos speakers are full range drivers or concentric because of the narrow angle they need to play in, and the dispersion characteristics of those drivers in the high frequency. Also, they are usually being played ~120hz and up to avoid omnidirectional waves. Just some thoughts to consider!
Hanging speakers on ceiling pain in ace.
But he got whole workshop.
😝
Toy clearly didn't get it at all, the most important thing of the cinemas is the HUGE screen, for sound surround there are plenty of already made solutions that are great, you're reinventing the wheel unnecesarily here.
Nah, it's the popcorn
@Zac you should have used a roller on the foil to get the air out of the butyl
Where can you get custom PCBs made for under $2 each, as you mentioned at the end here? (Did you include a link for that anywhere?)(Because you never mentioned the name of the place you found that makes them.)
in DUNE, they're ornithopters, not helicopters; they flap wings instead of spinning.
When I saw him whip out the breadboard for soldering I didn't know WHAT was comin'
Awesome video Zac! 😎
Brazil is exporting memes, it`s so funny that the meme from Nazare Tedesco cross the world and arrive at this video.
Couldn't you have just built the directional speakers into the cabinet of the existing speakers you have. The cabinets would have been much smaller and looked a lot less awkward
Awwww 🐈🐱🐈🐈 19:35
Nice video! Can you share the 3d print models for the angled speaker support?
NGL, I've always just rolled my eyes at augmented and virtual reality. It just felt like another gimmick, like 3d HDTV. Technology that nobody asked for but those glasses really piqued my interest. I'm a home theater buff, I have been since the laser disc days. I have a 7.2 channel Sony str-dn1080 Atmos receiver with Klipsch speakers all the way around, I have a Sony OLED 65" TV and an HTPC I've built into my entertainment stand which has 144tb worth of space and it's filled with games, Hi-Res Audio music, movies and TV and I can totally see these glasses being an extremely worthy addition to my setup. Esp since my receiver has a 2nd output that's can be changed at the press of a button. Now, let's see if I can afford these glasses
All that when you could just put on headphones instead lol
when using the dynamat stuff im pretty sure you only need a small portion in the middle of the material (not having to cover the entire area) .. for example a 6 square inch piece on a rear quater panel that is like 3 foot ... this coming from the "old timers" from the audio shop i worked at for many years.. not many people get it installed much these days though cause car manufacturers have their own stuff preinstalled now .. just my 2 cents
You can also buy pre made Car Audio crossovers from most brands....
I have had 3 sets of crossovers along my way and some offer better options than others, you can have + or - 3 db and other options...
I used to install car audio all the time and most component speakers have crossovers and people often only use the mid speaker to replace a factory speaker and sell the crossovers.
You are much better building a crossover rather buying one
@@pixelreflectorpro there is many options in after market car audio cross overs....
Cool tech. Those miters are rough though.
cool build, however, to get the most out of it, height-channel speakers should be in-celling mounted, the up firing ones will give you some effect but nowhere near celling mounted ones.
I traded a much more expensive guitar amp for a Crown Com-Tech 400 power amp from an AMC Movie theater. It has special AMC branded XLR input and separate passthrough. I Bought it just for the AMC #STONKS It will later power a separate folded horn 18", but for now, the Klipisch Professional line 12" floor monitor (from eBay) The main #JUICE will be the Behringer PMP4000 powered mixer pushing the dual 15" JBL JRX225. This caught my attention because #Movietheater
Hearing "older title" and PS5 reminds me I have been on PC for over a decade and a half.
it will sound garbage and if you think its working then its the tweeter only that's reflecting the sound because high frequency can reflect as they can be focused but the speaker driver produces mid or low frequency which spreads in all directions and is much difficult to focus this side panel will never do much you should use transformer tweeters to focus it well it will do the job .
Can somebody say run on sentence.
Any chance you could put links to the speakers you used in the description also please? Cheers
19:35 … I fear your cat sees me! 🙀😂
You are living my dream bro 😊
I remember there was a Visaton paper from the mid 80s which compared all sorts of speaker building materials, using the their then best anechoic chamber in Europe.
The winner was... something like i forget concrete bitumen sandwich or something like that. Or was it glass bitumen sandwich.
But for practical materials it was MDF.
However the conclusion was that you get the same exact outcome out of any wood if you just use an approximately 30% thicker piece. For side pieces, you can also just brace them on an odd angle. For the front, thicker and inherently deader was better.
But i also think nobody should really care about how good surround speakers sound, as long as they have vaguely the same character in the midrange and treble as main stereo speakers. Not that they necessarily do here with their cones of shame in the front and being used an indirect source, but... worth an experiment i guess :D
Console games lean heavily into object audio APIs, where the game tells the system the position of sound emitters, while the console figures out how to render or output this to a suitable spatial audio. It's less widespread on PC, where some games do that but the majority do internal audio rendering and only support the most standard types of speaker arrays. Outright crimes are common, for example you'd think good spatial audio would be quite important for Apex Legends including height cues, but it entirely lacks HRTF, it just has the crudest panning you might imagine and worse.
My verdict is out... on the idea of optical glasses. Humans weren't designed to focus so close for extended periods, currently there are so studies that support my basis. But the idea is cool!
Your production value designing, fabrication, and video audio quality are bar none Love it keep em coming. Thanks
Zac sucks at speakers. Zac chooses form over function. 50W woofer used in build, crap. One off center sub crap. DTS has twice the resolution, which makes sense. Garbage speakers, garbage processing. I would pay money to NOT watch any movies at his house. A pair of 901s would sound better.
I like the new editing
Always impressive!!!
wowthat's a lovely cabinet bro
They could at least have provided us with a discount for those glasses 🕶️
Nice rig, but you should have some cable guards under your rug. 🤓
You are a very lucky guy you got a lot of cash to do projects. Very good luck to you, you’re living my dream .
The subwoofer Good luck so much better in between The tower speakers as opposed to on the left
So you are saying to order these offline, like from a mail order catalog?
Great video, can't stand the mounts though. Hand made speakers that pretty deserve a better mount.
Cool project. I find the audio mastering on movies these days pretty annoying though. Conversations sometimes sound like whisper level, then giant explosions that blast your eat drums out. Could you EQ that out with a set up like this? They call it "cinematic mastering" but I think it's trash. lol
I have a 65 inch Ambilight Philips mini led TV. I consider a 75 inch. TV. How far away do you sit from the screen?
