Really cool you were able to get that done at 14:40, being able to customize with both wood and electronics makes for some really cool project like this one, glad YT put this on my feed today.
I bought a polk audio 12 inch sub with built in power. Its 450 watts. Sounds amazing and hits so hard with barely turned up. Paid less then 300 bucks for it at the time. I love building stuff myself but alot of them times i will buy pre-built then mod it my self. It ends up being cheaper.
I need to interject and get some information out there that you should add instead: - Structure and rigidity makes a very deep bass. There is a number of ways to do this, the "Window" method is the absolute best. Reference Dayton Audio's "prebuilt" cabinets for this. - The more dense the material you use, the deeper you can get the bass. - Port tuning is incredibly difficult, but there is software for this. - When building the cabinet, joinery is going to give you the "tightest" possible joint. This includes using box joints, or even basic joinery, like dados. - Instead of using wood glue, use Polyurethane Glues work best. - A Double Baffle should be a requirement. - You can get the MDF cut at Home Depot, near to size, and simply cut it to size (exactly) at home, making it easier overall to work with. - Be sure to properly mount the Subwoofer Amp, also adding some sealant to make sure it's a nice, solid fitment that has no leaks. The crucial part of a subwoofer is having it entirely tight and sealed. I built mine out of 2 3/4" mdf glued together, and I wrapped the outside in 1/2" oak & walnut, basically making it as solid as possible. A frequency test shows I get 20hz and up at the loudest points, and I have a "faint" sound near 15hz and it goes up exponentially to 20hz. Also: Box ports are easier to make than people may think, you can actually design the subwoofer, and even a basic speaker, from the port first and it'll make building the cabinet even more easy.
Exactly. I would also add that the point of having a filler in the cabinet is not to kill resonance but rather to kill standing waves. If your box is vibrating too much you've used a material thickness that is not adequate for your power level or just haven't baced the box enough. That being said the mat that the dude glued in does a whole lot of nothing.
Guess I have to be that guy: class D is not digital, it is analog. It uses high frequency switching for the amplification, but never converts the signal to a digital state. Nice build!
really cool video as usual no way I have the skills, talent, or time for this so I'm likely to just buy an off the shelf solution but I love this kind of stuff
Great video! Quick note/question: does the vocal audio sound a little muffled to anyone else? It sound like there's a barrier between his voice and the mic to me
I have a really old book from the 80's titled 'Subwoofer Design'. It was only about 400 pages. It was 400 pages of math and design considerations.... :P
My question for you: do you think there is a viable way to get power from speaker wiring/RCA? You could replace your current wired speakers that way ans still have power.
You mixed some stuff up with the power ratings. The amplifier should be **more powerful** than the rating of your sub prescribes. Ideally with some headroom. So if you've got a 400 watt sub, you should target for an amp that could handle up to 500 watt (at the given ohm rating of your sub).
Nope, because the subwoofer is a passive component, that is rated for peak Watt and RMS Watt, 300W RMS is the power that the subwoofer can handle not Its optimal working point You sould use an aplifier lower or equal than 300W RMS at the same ohm to avoid burning the copper windings when you put at max wolume the amplifier. A 150W RMS Amplifier can easly handle a 300W RMS subwoofer.
Been doing car audio for many years and this isn't how I practice my builds. The amp only sees the impedance so as long as that is within spec you want the driver to be able to handle the amp at max power output with some headroom. You're the one mixing up these things.
I wonder why haven't you talked much more about latency/phase, my guitar wireless (which is the same product basically) has 16ms of delay, this way you'll have a weird notch in the EQ due to phase shifting. But hey, if it works for you, I'm happy but I think it's worth to give it a look and mention it! I'd say test this with and without the wireless and hear if you feel a difference, with wire you should get even thumpier/deeper sounds. Another way you can do this is using the same wireless for the rest of the signal (I believe you can have 1 transmitter and 2 receivers)
I have noticed, that you often have some kind of earphones on, while working. Do you listen to things based on what kind of work you're doing? I myself have drastically different music between working on metal, wood etc. all the way to sketching and building miniature scale things.
Please please PLEASE WEAR BREATHING PROTECTION WHEN YOU'RE MACHINING MDF. That stuff is hilariously toxic and breathing in it's dust is AWFUL for you, PLEASE put on a mask of literally any description when you're cutting/sanding it.
1:36 Man, stop asking ChatGPT for the differences and consult some of the various explanations from experts over the years. Sealed enclosures typically have a more natural roll off of 12dB per octave, which blends smoothly with room gain. Ported enclosures, on the other hand, are designed to boost output around the port tuning frequency at the expense of a sharp roll-off below that frequency (24db, and it requires a hpf to not damage the driver from over excursion too). I take issue with "fast" or "musical" subwoofers. The transient response or "speed" of a subwoofer is primarily determined by the system's bandwidth and tuning, not the type of enclosure. What people perceive as "faster" bass is often the result of attenuated low frequencies (sub 40 Hz), which makes higher bass frequencies more prominent. You can correct the phase of a ported enclosure by pulling down some of that efficiency near the tuning frequency too.
That’s not a home theater that’s just a living room with a subwoofer. Also sealed subs are not “faster” that’s nonsense. Sealed subs are smaller and that’s their only advantage. Ports MAY have port chuff if you don’t tune them correctly. Ported subs are better if you want low extension.
a single 12 isnt anything to be worried about with noise there great subs but i promise you this unless you live in an apparment the only preson thats going to hear you is you
Hey Zac, since you dont neet your old Sub, DM me! I can store it rent free till you need it. I‘ll promise I will take good care of it and only play moderate loud songs on it. Thank you!
Serious tip: take a soldering course. Self learning is nice, but the industry has way more experience. (UA-cam is great to learn, but for learning soldering it's not that great yet)
@NilsBomstromAho DIY Perks recently released a video about making a DIY wireless home theater system. But it came out so recently that Zac couldn't have known they were also doing a DIY audiophile level project. Just a coincidence. Both channels are phenomenal and bring their own unique solutions to the table.
DIY Perks did a lossless laser link recently on the TOS link protocol to connect up a wireless surround setup including bass sub. Yes, needs line of sight, but doesn't suffer from compression / lag.
Forst off like your vids, As a speaker builder myself, all those lips and edges sticking out on the front baffles are no good . They will cause diffraction. It may not be a huge deal at sub frequency.
GLORY!!!'m favoured, $140K every 3weeks! And am retired i can now give back to the locals in my community and also support God's work and the church. God bless America 🇺🇸 ❤️
Hello, how do you achieve such biweekly returns? As a single parent i haven't been able to get my own house due to financial struggles, but my faith in God remains strong.
YES!!! That's exactly her name (Elizabeth Ann Larson) so many people have recommended highly about her and am just starting with her 😊 from Brisbane Australia🇦🇺
Always ALWAYS use THREE feet under speakers, not four. It’s all but impossible to get four points in the physical world to describe a single plane, but it’s even more impossible for three points to NOT describe a single plane, whether theoretical or physical.
25 watts of dirty power will destroy a 100 watt speaker WAY before 100 clean watts will destroy a 25 watt speaker. Really flirting with a lot of misinformation in this video.
About the wires, DIY Perks made a video about it a few days ago in case anyone missed it it is worth watching
I dont think the laser line of sight limitation would make them easy to use in a house.
loved the side by side demonstration. really enjoyed it on my Creative Pebble V3 8W speaker.
Thats one chubby TIE Fighter!
I thought you were going to build a servo subwoofer. I never thought of putting the wireless receiver inside the speaker. Good idea!

They make plate amps that already have wireless functionality.. Even so nice job
i love how both you and DIY Perks put out a video involving wireless home theater speaker builds in the same week haha
Guess I have to be that guy: class D is not digital, it is analog. It uses high frequency switching for the amplification, but never converts the signal to a digital state.
Nice build!
This channel is so fun!
really cool video as usual

Great video! Quick note/question: does the vocal audio sound a little muffled to anyone else? It sound like there's a barrier between his voice and the mic to me
Sounds like some sort of noise reduction
Yeah I heard that too
Parts of the video definitely sound like his lav mic was under his hoodie. Pretty lame mistake for a video about sound equipment.
Car Audio Fabrication enters the chat....
That steam punk Tie Fighter sounds great lol
Huh. Interesting new information thank you!
I love your videos man they entertain me and my kiddos every time you drop a new banger
You're going to want to fabric over your port , that close to the floor it will collect a lot of dirt and trash, otherwise great build
Now you need to build a second one :)
I have a really old book from the 80's titled 'Subwoofer Design'. It was only about 400 pages. It was 400 pages of math and design considerations.... :P
If only i could live in your house! Its so futuristic!
But how much did you spend versus the store bought?
Naiiiil Gun!
Imagine combining this with the recent @DIYPerks laser surround sound system 🤯🤯
Really love the video! But class-D doesn't mean digital. Also it looks a bit like a TIE fighter 😅
Thank you! I thought I misheard the “Class D” comment.
Well it could be classified a digital beacause it's switch mode, square spwm signal through a low pass filter
Im suprised he didnt make this transparent aswell
It has a more dominant presence
you forgot to talk about bandpass subwoofers
What is Sound Qulity?
My question for you: do you think there is a viable way to get power from speaker wiring/RCA? You could replace your current wired speakers that way ans still have power.
Hey Zac or anyone who knows, what 3d modeling software do you use? I never get a clear shot of it in video, thanks in advance
it looks like Fusion360. Very capable software and available for free for personal use
You mixed some stuff up with the power ratings. The amplifier should be **more powerful** than the rating of your sub prescribes. Ideally with some headroom. So if you've got a 400 watt sub, you should target for an amp that could handle up to 500 watt (at the given ohm rating of your sub).
Yeah, I was like "am I remembering wrong?"
Thanks for clarifying.
This reduces potential distortion from the amplifier side
Nope, because the subwoofer is a passive component, that is rated for peak Watt and RMS Watt, 300W RMS is the power that the subwoofer can handle not Its optimal working point You sould use an aplifier lower or equal than 300W RMS at the same ohm to avoid burning the copper windings when you put at max wolume the amplifier.

P.S. I'm not a fan of clear enclosures, but to each to their own.
Please more speaker video any kind speaker specially passive speaker 😅
Hey Zac! Nice sub - I could really hear the difference ;)
What TV do you have?
It looks like an 88"
Please please PLEASE WEAR BREATHING PROTECTION WHEN YOU'RE MACHINING MDF.

Lets go Zac!
Really, this channel needs to be renamed to "Zac Builds ONLY Walnut", lol.
does having the port on the same surface as the driver cause phase cancellation?
No not realy, it doesn't really matter what surface you place the port or driver on for a sub. The wavelengths are so long that it doesn't matter
I'd say the real phase problem would be on the wireless unit first
@@NoxMessor100%. He's not addressing latency at all until he converts all the other speakers to the same wireless setup.
diy perks just released a vid of him making the coolest speaker set I've ever seen, but that guy's on a whole nother level
I hate the fact that the post mortem analisys if onluly for members now, but I also understand why...
Nice
Bro build a rotary sub
I just found this channel. Am I smelling ADHD? We smell our own.
Thanks for the content.

Taking about having everything sir tight, i like to caulk all of the inside corners with silicone. It has a slight flex to it and won't crack
No speaker can sit right next to a wall. Especially subwoofer. Do what you want is not going to sound right without proper placement.
You gotta get rid of whatever mic you’re using when you’re in your shop. It’s sounds like you’re underwater.
You didn't give pros/cons for open baffle. 😀
Muy buena, gracias por inspirar!!!
Why it has to be walnut as always?
Because why not?
a single 12 isnt anything to be worried about with noise there great subs but i promise you this unless you live in an apparment the only preson thats going to hear you is you
Please disable auto title/description auto translations. It's poorly implememted and makes most sentences sound stupid.
As someone with an actual home THEATER this hurts to watch
6:25 😂😂😂
Just cranking out these builds.
Another great video.

Didn't Dave Jones on the EEVBLOG make one years ago? Or was it Ben Heck? Probably both and pretty much all the pros... X)
@ Dave wasn’t the worst, good enough for hobbyists, but if I would deliver that quality at work I need to start over
tie fighter
I can certainly say that both subwoofers sound the same on the video but thats okay.
👍
VERY NICE! With all you recently Dayton audio purchases I get the feeling you have discovered HexiBase's chan LOL :)
Also most freely available speaker design software are brim filled with their drivers so it is very easy to choose
Subs make things have umpt, but most our headphones can't enjoy his work cuz,we gots no subs
The guy thinks he is DIY Perks. /s
I don't get it
@NilsBomstromAho DIY Perks recently released a video about making a DIY wireless home theater system.

Common bro, DIY perks wasn’t the first to build a speaker 😂
This guy is DIY Peeks with Doug Demuro voice
both are very good at what they do
Holy 🤯
Crazy work 🙏
Top 20 likes lets goooo
I thought bro was about to actually build the sub this disappointed me

Zac you need to pump out 10 videos a day. That's all
👍🏾💪🏾
15:00 you set out the solder mask to cure under UV behind a glass window. glass blocks almost all UV-B and UV-C.
whats wrong with your audio?
Amazing...
well Im listening to this on a phone , so both speakers sound the same
I think its cheaper and easier to just buy a prebuilt sub. A sw 1400 klipsch subwoofer will hit flat to 15hz in room for 699$
More like $1200, and that's for the cheapest one
No its always on sale at adorama for 699. Just use slickdeals. Thats where i got the two of mine
Not even 3D printed, literally worthless /s
Massive🤭
Ewww wireless audio...
May as well just use a Bluetooth "sound bar"
Trash.
I think I would prefer that it has a top and bottom piece. That way it matched the others a little more.
It needs a grill, in my opinion. If anyone accidently touches the driver with anything, it is game over for high audio quality.
Early gang. 👻👻

Sealed sub + more power >>>>> any ported design. Check all world class subwoofers in the highest price ranges to confirm.
