Absolutely fascinating series of videos! Thanks so much for the endless hours you both put in to making these. I think this is the 1st video I have seen showing how the frequency and time responses changed as one adds more treatment. Looking forward to next week to see what happens when the the membrane traps are added into the equation.

So happy to know I’m not the only one confronted with unexpected room responses from acoustic treatment!

Your videos have helped me learn so much about room acoustics! Thank you so much for making these!

Thanks so much for all of your incredible videos, Jesco! I really appreciate the time and effort you put into educating people about acoustic treatment.

What a fantastic series of videos!

Damn , this is very fascinating guys. I have quite similar room size. Learned a lot from this series. Really appreciate this type of content and the details of it

Loving this series of videos. Would corrective EQ work to iron out those few areas that still need some work such as the 62Hz?

This is great work, very enlightening. I've found massive differences in my studio by moving my speakers around. High low end energy when the speakers are closer to the front wall and further away from the listening position and more midrange articulation from when the speakers are closer to the listening position. However, true to physics, the room mode is still there, just at varying degrees. Edit: I see you tried speaker position. What about turning the room around, leave treatment where it is and place the speakers on the other side of the room. ]

Wow this data is so revealing! Awesome to watch.

Thanks for the video guys, awesome overview.👏 *Question for the Q&A:* Graham, can you share some more details and thoughts on this nice desk of yours? Is it comfortable, how does working on it with a mouse and keyboard feel with those gaps and how did you manage to integrate external rack gear in a way which makes sense ergonomically and acoustically? I find it a super interesting idea and I’m honestly wondering why I haven’t seen slotted desks used more often, from an acoustics standpoint it seems to make total sense. Most important question - what would you like to change or wish you had made differently on that desk design? Cheers! ❤️

Brilliant. This is what I've always wanted to see

Would love the design for the slotted desk :)

Hi Jesco!! Your workshops very helpful and comprehensive but I had a question tho: my room is a one car garage (5m x 2.75m x 2.50 m) with an iron door on one of the short sides. How should I deal with that? Thanks again for your amazing tutorials!!!!

Wow What a journey!

Super informative. Thank you both!

It seem that those large panels in front corners and lowered ceiling reduced-changed too drastically the room size. Thus switched original room modes to new ones and created unexpected problems.

Hmmm,, do you guys hate Genelecs,, 🤔? Supercool flick 🥰. Cheers and thanks for your time and work,, 🍻🍻😎👍‍‍👍‍‍!

I learned a lot, thanks!

26:55 What does the layer-by-layer panel (side, back wall) consist of? Are there rigid walls inside (front, back) or is it actually a large piece of mineral wool of different density wrapped with fabric on the frame?

Have you been able to test how effective speaker isolation pods would be at addressing some of those problems in the low end?

why not use triangular traps in the wall-ceiling dihedrals?

Mid bass response in the room looks terrible and I'm going to guess is modal. I imagine if you had a subwoofer and you cross it over quite high (140hz or so), you will probably smooth that out and the expense of a bit of stereo image. Since you are using 1/3 smoothing the loss is actually quite significant. Music would sound a bit thin and bright. Rather than laying the panels across the corner, you should have just used a thick baffle trap with a mixture of rigid and "pink fluffy". You basically have every single surface treated and the low end is still quite poor. If this video serves any purpose, it's to show exactly how not to set this up. Your decay times are going to be well under 200ms (or should be) and it's going to sound awful. Remove the rear wall treatments or add some sort of diffusion to them and get less but thicker panels, so you can retain some of the higher frequency energy. Since you in the nearfield, it would make more sense to treat the boundaries closest to you and the speakers and then leave the rear wall as diffusion. Sidewall reflections can be beneficial and there is no conclusive evidence that treated them is a net positive. Keep in mind that when you are mixing, the avg persons room is far worse than yours. As long as it's in check your mixes will turn out fine.

Awesome Series! When you checked your predictions for how much the lowest value peak to highest value peak difference was, you halfed the number that REW showed. Why´s that? (Its at around 6:20 in the Video). Pumped for the next part, cheers!

Awesome video. I wonder about the pink fluffy behind the corner traps? Did he completely fill the air gap with plain old pink fluffy insul?

At 6:19 - how do you do that selection in REW? Great video, guys!

If I measure an untreated room with a pair of speaker brand A and and then another pair of speaker brand B I get two different measurements because of the speaker differences. So do I have to do room treatment depending on the speakers I'm using? And if I get a new pair of speakers band C do I have to start all over with room treatment? Why do we treat the rooms acoustics to fit the speaker and not the room itself

Part 2?

There’s no part 2 on the channel lol

I have a room this size. What’s the cost on this amount of treatment? Ball park figure, not a quote of course.

Where's part 2????
