Super thankful you’re alright after an accident like that. Also really grateful this series is back. Thanks so much for all you share about life, music, and everything else.
Can’t thank you enough for this! Very few people have the means and motivation to go this deep and try out everything, and then share all that information freely in so much detail 😮 Truely invaluable!!
A year later, saying this video is a HUGE help for where I am in my own process. Funny enough, I sold pipe insulation at an old job and have never thought about them for tube traps. Eric is one of the, if not *the*, best educators out there about all sorts of audio things, whether that’s mechanical, technical, or creative.
Hahaha, that poor ATC - that’s great. Smart move on cutting the cylinders, Eric! Thanks for sharing, and I'm glad you’ve recovered after that accident.
Absolutely fantastic. I worked in the high end home theatre industry for 20+ years so learned a lot about small room acoustics and aesthetics. Love your attention to detail and your tenacity.
My favorite line “sorry ATC…😅” thanks for documenting and sharing the madness that is acoustic treatment. The audio world is better than it was before this video. 🍻
Huge thanks for taking the time to document all of this amazing and hard work-the fact that you shared this as a resource for everyone is above and beyond. I have enjoyed the many details you observe and the way you approached the entire process. I want to come visit your room! Regards from southern VT.
Your channel should be called Valentines Audio Bible. Dude I cant thank you enough for everything, im in a process of a new room build as well, and you probably just saved me a lot of money and time and energy sharing what you have learned! I swear I am always on the same wavelengths as you. its just freaking wild, everything you say, things that happened, your philosophy's. Just on point.
OMG, the breakthrough with the Helmholtz resonator must have felt so good! I'm definitely gonna try here in my room, I've always found them confusing, but you made it feel a doable task. Thank you so so much for sharing this!
Watching this a second time and just realizing: There is A LOT of misinformation in this domain. I mean, I kind of had an idea, but, wow! Everyone is trying to sell something, or regurgitating information from someone trying to sell something. These unbiased experiments are pricless to the whole audio community. Tha ks so much Eric, you've saved me a tonne of time, money, and frustration!
Amazing. Thanks you so much for your hard work and persistence. this series on your studio is incredible. so comprehensive and accessible for a fellow like me to apply in my room... thank you from VERNON BC CANADA
I am SOOOO glad I didn't have to go through this much PITA to get my room fairly flat. LOL. I ended up with 6" Bass traps in my corners and (14) 2x3 3" 703 based panels. After all the gear got put in along with a 7ft couch (room is 11x16' and oddly shaped), it was a matter of moving my monitors around a bit and using the built in DSP. Very happy now. Was a decently long process, but your project puts me to shame! Thanks for sharing your journey and wish you the best!
You're the man, Eric! you really are a DIY guy all the way! if I was in your shoes, I probably would've called Alan sides -but that may have cost way too much and not as much fun doing it yourself ... Uneven walls and a slanted ceiling may have been an easier way to start BUT... then we wouldn't of had this great educational video.. Most of us don't usually have the advantage to have uneven walls. We're more in rectangle and square rooms as well.
Very informative, thank you so much for sharing. I am in the process of getting my home studio up in our new house. Made me help decide what to go for as first tests.
53:45. This is so Eric valentine. I just love it. I’m watching this whole thing and I couldn’t appreciate it and dig it more. You’re an inspiration brother. Love everything you do.
Yes! Amazing! Has anyone A/B'd tube traps with just big rectangular gobos? Seems like their function is mostly due to them just being large porous absorbers. And what are your plans with a desk or console? Putting a big reflective surface in front of your face will add a lot more problems.
yeah I'd be curious to know how it compares to just 1-2 ft of low density fluffy fibre. much easier to just frame up and cover with fabric. Awesome breakdown though Eric, this really is a masterclass in practical acoustics. I would have never of thought having the door open would change so much!
Hi Eric, wonderfully informative video as always! If you want to add back decay time in the frequencies that have less, you could build quadratic diffusers. The quarter waveform for 250hz is a little less than 14" so a diffuser of that depth will have a broad spectrum of diffusion down to 250hz. They should be placed with the room modes in mind, as well as angle of incidence from the monitors to the listening position. There are some really interesting designs, and it's possible to use the back side to add additional absorption. You've done tremendous work already, congrats! I loved the tissue paper trick
Oh hell yeah! Hope all's well over there! Can't wait to see how it all turned out, and what you learned. (I'm building my own new control room in about 1.5mo so this stuff is right on time!) Cheers! x
And yes, very glad you're ok after the bike incident. I'll also have you know I just produced a band that the opening track was called "Dog", and for many reasons I will think of you moving forward haha.
I’m new to this Mr. Valentino, but this is wonderful. I am so grateful I found you amazing amazing work. I am looking forward to doing a Studio the same way. And yes, I’m a perfectionist.😅
Eric, you probably covered this in the past, but why is the tube trap more effective than just stacking non-rigid fiberglass or mineral wool insulation on the entire front or back wall? That seems like it would be quicker than building traps. I guess the air space in the tube is more effective than having that space filled with insulation?
I'm also very curious. When I put the data into an absorber calculator, just filling all the space with mineral wool seems to be more effective than mineral wool+air+mineral wool like these pipes are
4:27 I had a similar experience with a record that I just finished working on recently! One of the few that I didn’t play on, but especially one acoustic track that was a last second add-on, the singer and his dad played together and nailed a perfect take the first time. It was magical, I got goosebumps.
Floods, face flops and coughing up construction dust. Glad the end of the rainbow is in sigh!! Great insight on the struggle of low end in the control room.
Amazing detailed video, best online! Quick question though. I am going to build the tube traps from the pipe insulation. Should I also stuff the inside with Rockwool? Would that make them work even better? Thank you.
What's the difference in performance of the tube traps between empty tube trap and tube trap filled with loose fill absorber (eg fibreglass) in the cavity ?
I can't believe you used that speaker like that.. :) maybe a piece of ply in between would at leaste spare it from scratches... Great trick with the paper on the hole..
Hey Eric, have you ever tried experimeting with filling the tubes with low density insulation like another company's tubes? They claim that through isothermal properties they're able to achieve better absorption at lower frequencies that way compared to a tube with no stuffing of the same size.
How do you feel the tube traps relate to the false wall build you did at Topanga Canyon? If room allows, is there a big difference of 20” tubes vs 8”? Any experiments with filling the interior of the tube with more insulation (loose rockwool, recycled cotton,etc)?
Besides from being an awesome lecture in acoustics this is a proof that if you do things properly and dont skip any corners you get so much greater results, you are a true inspiration of that! Q: In the first videos telling us about the new studio you talked about having like a "mix with the masters" thing where people can come visit and learn from you. Is that still a possibility in the future?
This is the single greatest and most epic flex in the history of pro audio!! I love it 👍 also amazing video Eric THANK YOU for sharing this process with us!
Thank you for all the great content, love your videos! Is there a specific reason why you've decided to position the speakers so close to the back wall? Would a bigger distance to the back wall improve the bass response in the room or is it irrelevant because of the way the speakers are designed?
I was watching a video where they had problems with the floor and what they ha done was lay a tube trap on its side on the floor and it made a major difference.
Eric, love the channel. In regards to the tube traps.. you mention that the plain old tube traps are much more broadband than the Helmholtz traps, but is my understanding correct in that the main difference between the two are just the end caps? Being the size of the hole you use to tune the frequency.. does that end cap with the tuned port hole simply mitigate the broadband nature of the trap? I hope this makes sense. Thanks, and much appreciation for your time and knowledge.
Awesome! Question: Why wouldn't you do a meter (~3 feet) deep rockwool wall in the back and just be completely "done with it?" In the front it makes more sense with tubes as its good with the extra efficiency/space there but I feel just a rockwool wall, deep enough, doesn't take alot more space and does trap the bass all the way down, better than tubes?
I wondered the same thing, but R30 would be cheaper and more effective at absorbing low frequencies at that depth. Would love to see that 3' of R30 on the back wall vs. tube traps.
Great job getting the room pretty darn flat! BTW, the Beatles recorded in Studio 2 at Abbey Road. Pink Floyd recorded Dark Side Of The Moon in Studio 3, an amazing room! I was recently at Abbey Road, I'm putting up a video this week about my recording project there.
The amount of tubes at the end! :D @Eric, could the frequency response be significantly altered also because you've fundamentally made every wall irregularly shaped and much less parallel/perpendicular to each other?
Kind of seems like you are inadvertently making each wall of the room more like how an anechoic chamber would work. Or possibly having so many curved surfaces of that particular radius disperses the lower frequencies more randomly so they don't converge/cancel in the same spots?
This is pure gold Eric, thank you! The room mode/resonance at 44 Hz is easy to see in the, but the one at 57 is harder to see imo, do you just expect it to be there due to the floor/ceiling dimension? I'm sad to see that the limp mass absorber didn't do anything for you, I made what Ros Gervais calls a panel absorber with the same math/construction but a hard surface on front (I chose plywood) with good effect, altho I don't remember measuring after the fact but it tightened up my room considerably. I want to experiment with tube Helmholtz resonators, looks like they are cheap/easy to build and very efficient.
Another Freakin' Awesome Video... Question; Your Mini-Split AC unit on the wall, do you have plans on making it quite as well or is that not an issue in the room? Thx

Absolutely amazing episode! Was struggling with the Helmholtz thingie, this made all the difference. Thanks! :)
OMG, the breakthrough with the Helmholtz resonator must have felt so good! I'm definitely gonna try here in my room, I've always found them confusing, but you made it feel a doable task. Thank you so so much for sharing this!
A question: can the tube trap be used as an speaker stand?
Thank you so much for sharing your time and knowledge. I can't wait to build these tubes. I appreciate the experimentations!
Incredible journey you've been on! Thanks for carrying us along for the ride. Wow!

awesome man! thank you for sharing all your hard work!
I learned a lot about Helmholtz resonators and tube traps, thank you so much for sharing all of that.
Very glad you recovered fully and speedily, Eric. Head injuries are no joke.

Great to see you, Eric! Thanks again for sharing so much helpful info in an amazingly fun way. Cheers!
Very informative, thank you so much for sharing. I am in the process of getting my home studio up in our new house. Made me help decide what to go for as first tests.
Thank you very much for doing all of these videos. So appreciative.
So happy to see your tube trap construction! 👍👍👍
So good to see you back. Glad you recovered from that nasty accident. Congratulations on the studio!
i'm now more excited to see how you cover all this up! :)
53:45. This is so Eric valentine. I just love it. I’m watching this whole thing and I couldn’t appreciate it and dig it more. You’re an inspiration brother. Love everything you do.

the giant tube traps behind you gives a space station vibe. crazy stuff
Thank you so much for this Eric, you have no idea how much I needed this today. You are a wealth of knowledge and experience!
And yes, very glad you're ok after the bike incident. I'll also have you know I just produced a band that the opening track was called "Dog", and for many reasons I will think of you moving forward haha.
So glad you’re a “dog person”, Eric! Dogs are great assistants + as a bonus, they have “dog’s ears”, of course! 😉 Good to see you and Max are ok.
Wow man. Glad you are ok. Good on your Son for knowing what to do in that very stressful situation.
Hooray! Eric is back! The saga of the dream barn studio resumes.
Glad to see Eric in the audio trenches figuring this out for us!
A sound treatment mad scientist! Thank you for this wealth of information

I have really missed these videos!!
Floods, face flops and coughing up construction dust. Glad the end of the rainbow is in sigh!! Great insight on the struggle of low end in the control room.
So inspiring, I'm hoping to my own barn studio in the next couple of years however it's much smaller but there is a lot that I will take from this.
It looks so great congratulations ❤
Love the new Grace tracks, so funky.
Great to see you back Mr V😁
Starts talking tube traps around 1:23:00
just starting this one now. glad you're back!
We were missing you, glad yr okayyyy✨
Grace's new stuff sounds awesome!
Amazing detailed video, best online! Quick question though. I am going to build the tube traps from the pipe insulation. Should I also stuff the inside with Rockwool? Would that make them work even better? Thank you.

fascinating! thanks for sharing. very inspiring! I just built a studio last year and I'm gonna go back and do some more measuring :)
You are an absolutely golden human being
Did anyone notice the massive dent in the Right Channel Strauss's woofer @ 56:39? Oh eric...
Yes!! I couldn’t stop looking at that! Surely Eric is aware of it?
Nothing like seeing $60k monitors with a smashed dustcap! I’d have to order a replacement woofer immediately to keep my OCD from killing me!!😅
Great job Eric! I'm team tubes now as well. Haha!
❤ missed you heaps! Glad you're ok.
How do you feel the tube traps relate to the false wall build you did at Topanga Canyon?
If room allows, is there a big difference of 20” tubes vs 8”?
Any experiments with filling the interior of the tube with more insulation (loose rockwool, recycled cotton,etc)?
Very interesting discoveries Eric!
Did someone find a reseller of them tubes in Europe/Germany? Or maybe a similar Product?
Nice to see you back!
Fantastic and interesting - thanks for sharing all that you've discovered. Curious if you ever considered the PSI active bass absorbers?
Welcome back Eric 😊
Yesssss!!!! Finally back!!!!! Missed your videos 🤘
Besides from being an awesome lecture in acoustics this is a proof that if you do things properly and dont skip any corners you get so much greater results, you are a true inspiration of that! Q: In the first videos telling us about the new studio you talked about having like a "mix with the masters" thing where people can come visit and learn from you. Is that still a possibility in the future?
dear lord you are a genius
You know you have money when you're just casually using an ATC speaker as a cutting jig stop.... Love these videos lol
Using a damn ATC monitor as a table saw fence! Now that's gotta be a first!
Interesting mic placement on that tweed, sir!
This is invaluable
Look up Limp Bag Membrane Traps. They did a great job in my studio in smoothing out the lows. Very easy to make.
With the melamine foam are you not concerned that they have formaldehyde in them in regards to a health risk ?
thanx Eric, sorry about your spill...always wear a helmet.
Can someone help me with what these tube traps are made of? What are they called?
Looking to find how he mounted tube traps to the ceiling. Anyone know? Looking to do the same
Thanks a lot for all the information! Do you fill up these tube trap with more rockwool or something or is there empty space trapped within?
Space within
The ATC speaker serving as a sewer pipe cutting fence next to the table saw.... I'M DEAD!!!! 😂🤣
This is the single greatest and most epic flex in the history of pro audio!! I love it 👍 also amazing video Eric THANK YOU for sharing this process with us!
Thank you for all the great content, love your videos! Is there a specific reason why you've decided to position the speakers so close to the back wall? Would a bigger distance to the back wall improve the bass response in the room or is it irrelevant because of the way the speakers are designed?
This is incredibly deep information..........
Can you solv all this problem building up anechoic room?
I was watching a video where they had problems with the floor and what they ha done was lay a tube trap on its side on the floor and it made a major difference.
Eric, love the channel.

Ahhh cool thank you for the clarification on that :)
Absolutely amazing work. So valuable. Did you try by maximizing speaker position first?
Welcome back !!!!!!!!!!!!!!!
The amount of tubes at the end! :D
@Eric, could the frequency response be significantly altered also because you've fundamentally made every wall irregularly shaped and much less parallel/perpendicular to each other?
Kind of seems like you are inadvertently making each wall of the room more like how an anechoic chamber would work. Or possibly having so many curved surfaces of that particular radius disperses the lower frequencies more randomly so they don't converge/cancel in the same spots?
Thanks Eric! Where are you typically purchasing your materials for tube traps? Depot or Lowes mainly?
This is pure gold Eric, thank you! The room mode/resonance at 44 Hz is easy to see in the, but the one at 57 is harder to see imo, do you just expect it to be there due to the floor/ceiling dimension?

glad your back
Is there any acoustic reason for the carpet in the control room?
Could you cover the tube traps with fabric to make them more aesthetically appealing or would it ruin the effect they have acoustically?
Another Freakin' Awesome Video... Question; Your Mini-Split AC unit on the wall, do you have plans on making it quite as well or is that not an issue in the room?
Thx
