After 10 years of changing speakers and amps, dacs and cables, i understand now that room is the most important thing of my hi-fi sistem

This is one of the best audio videos I have seen. If this does not convince someone of the importance of room treatment nothing will. You have probably both improved the listening experience of your viewers significantly and saved them a whole lot of money since room treatment is a lot cheaper than electronics and speakers. Well done.

Ron, I can only speak for myself, but all I have is admiration for your amazing endeavours and being able to, through sheer hard work and your dedication to detail, achieve your goal. You, Sir, are a true inspiration to home audio enthusiasts & more serious audiophiles alike. Chapeau, good man! Paul in Japan, (ex-Scotland).

The decrease in boom and the increase in detail are amazing

I did not take any of the work that you did here as an attempt to show off or be prideful. I truly appreciate the dedication and information that you have shared. Please continue to keep up the good work and sharing the knowledge.

Ron, I agree that these are some of the best videos you have ever done. The superiority of this series lies in its 1-2-3 punch: 1. You TEACH in a calm, organized, non judgmental matter. 2. You allow the viewers to HEAR for themselves the improvements each step of the way. Sort of like "a picture beats a thousand words principle." 3. You back up any subjectivity objections with MEASUREMENTS and graphs. These three punches satisfy the novice and the experienced, the hearing focused and the measurement crowd. Well done. As somebody who cares about the audiophile community, may I humbly offer up a suggestion? Could you better package this series with a general heading of your choice combined with subheadings for each video. This series is too good to be hidden or only viewed in partiality. Right now I find the videos too disjointed from each other by titles. Having a main heading and sub headings with each video develops a continuum that helps people identify it as part of a series and in what order. An off the cuff example might be the following: Room Treatment A to Z. Part One - Untreated Part Two - Adding Room Furnishings Part Three - Bass traps Etc, etc. This simple step will generate more views, which is what I would like to see. Having a main title and subtitle with each video will also make it possible to add to this series in the future as you see fit as it develops into a master class. Frankly it's approaching that already, certainly from a KZfaq perspective at the very least. Lastly, I hope you round off your series with some dsp additions. There's still a bit of voodoo surrounding that topic, at least for me. Thanks again Ron.

I went did it. After working with asc on my room which is a dedicated room which I built. It’s 19’ x 28 1/2’ with 12’ ceilings and no windows or openings. After going through different equipment and speakers before treatment by asc . I now know what my equipment sounds like which is a lot better than I thought. My bass is unbelievable and the midrange and high frequencies are so much better that when played at real levels it doesn’t sound loud. I can now turn volume up without my ears telling me that it’s too loud. This is the best video about room acoustics that I have encountered. Thanks for sharing your experience and doing all the hard work. Wally

Best audio series ever!!! The changes are brilliant and even the last tweak of absortion is noticeable!!! Thanks for taking the time and work to post this.

I’m in the process of treating my room. After years of reading, watching videos and procrastination I’m finally ready to start implementing what I’ve learned. I’ll definitely be referring back to this series as I go along. Thanks for taking the time to do these

There must be a ton of people out there who have spent a lot of time and money (me included) swapping out equipment (mainly speakers) to try and find the right sound, without realizing the room is the issue! Your series of videos are simply fantastic. Glad you had the foresight an resources to put them together. There certainly is no argument as to what can be achieved with the right approach and mind set. I am fortunate enough to have a tolerant wife and she has let me do all sorts of crazy stuff to the room achieve a better sound. All I can say is, it's worth the effort. Sit back and enjoy the music....

This series has been wonderful. I decided a long time ago the room, treatment of it and placement of speakers within it was ~80% of the audiophile equation. You are helping other folks understand that. Kudos!!

Awesome video, Ron. Best in the biz

I'm glad there is more to come there are still a lot more on the table! I'm very excited for this! I lost a good friend a few years back the late great Tony Bolton who was also a reviewr in the UK. I lived with him for 2 years & I learned so much in that time! This room takes me back to all the talks we had about tuning the space. I'm in the process of building a studio & looking back into room acoustic's! Thank you for making this!

BRAVO Ron!!! The difference in sound from bare room to most recent treatment is amazing! Great work! Truly enjoyed this series. 👍👍👍

Hey mate. Just wanted to say your previous video is the best one I've seen about the benefits of good diffusion. Most videos and articles are just telling you why it's beneficial.

Wonderful video, thank you so much. My takeaway is - why aren't open baffle speakers more popular than they are? It seemed to me that switching from box to open baffle speaker immediately did the job of a ton of room treatment. Anyone else?

Again - thanks for this amazing series. This is the first time we can follow the effect of various treatments and how tthe effect adda to the prior. Fantastic! And congrats to a great listening room!

Sweet Shed. Great series. I'm glad you said you're not done. The more you make improvements the more your ears learn and thus... the more improvements you can find. Once you identify any given acoustic issue (noise, bad reflection, resonances etc etc) it is very hard to unhear it, so it must be fixed... cheers.

As someone who just finished building a dedicated room last weekend (10'x15'x23') and just put on the floor, against the wall, about 15 acoustic panels (many problems left to tackle), THANK YOU for this series! I can get a much better understanding of the impact of each type of treatment. The timing is really great, it's perfect! Will probably steal your idea for the floor to ceiling corner bass traps... ;)

Excellent series in a much under represented area of “it’s the room bruh”. My GIK alpha panels made huge diff for me & I wish I knew more 10 years ago when I starting buying gear. I found the final treatment in yr room handled bass frequencies with such clarity & finer texture to be a sizeable improvement. Much Congrats!

This was done superbly! The tiered demo adding one more treatment at a time was brilliant as it clearly demonstrated that any room can achieve "better" with incremental steps allowing anyone, on any budget, to slowly improve the soundstage in their listening space one step at a time. Well Done!!!

This video (and the associated series) is the best thing you've ever done in my view Ron. It's brilliant to see some youtube reviewers really starting to talk about room acoustics. I also love the little story about the diffusers and the vision of some guy spending countless hours cutting and gluing together the panel to sell for $80. 🤣

By far, the most interesting and helpful series of videos I have seen since a long long time. Thank you!

Thank you Ron for these excellent insightful and educational videos. Someone earlier mentioned the importance of titles and organising these videos in a way that makes them easier to find. This is like an educational series on room treatments. I for one will definitely want to revisit these multiple times when treating our room down here in Australia. 👍😎 Your humility and sincerity is obviously and of course appreciated

The final treatment sounds so good! Amazing, how the recorded reverb of the music becomes clearer wirh every treatment step 😊

Great series and ready for more to come. Thanks for the ride and I look forward to what comes next.

Great work on room treatments. Good job shining a light on this underspoken about issue

great job! this series is golden (i'm still gonna airbnb the shed)

Kudos Ron! What a fun journey. Keep up the great work

Very inspirational series. I fell in love with room acoustics many years ago as a teenager when I "treated" my dorm (cork and carpet on the walls and ceiling) and I "saw" what the "treatment" did. Now I got my own dedicated 20m2 listening room/mini home theater and I always try to get the best of it based on info I find in the net, info provided by articles, lectures or channels like yours. Keep the good work and I am eager to see upcoming videos on acoustics. Sorry for my english if I did some mistake as english is not my language.

Too many people don't appreciate what room treatment can do. Your series of demo's will hopefully inspire others to follow the room treatment path. It's well worth it!

This Evolutionary Process has clearly made drastic Audio Improvements! Room issues should be considered First before any other Tweeks! Ron, this has been the most Educational and Informative Presentation you have produced! Thank you for all your hard work in bringing this to us!👏

This video proved to me how important room treatment is. It's amazing how much more detail you hear when you get rid of all the miscellaneous reflected sound and resulting echos.

Awesome result, I bet it sounds incredible in person! You're right about aiming for better and not necessarily a huge project like yours. I have a crappy bedroom just a couple feet shy of being a cube. It's covered in inexpensive foam which isn't anything fancy, but getting rid of those reflections is awesome. I just enjoy sitting in that room even with no music playing because it is so quiet and peaceful. It won't win any measurement tests but compared to bare walls there's no question. The progression of treatments shown in the video illustrates this well.

I only have a small amount of treatment but I did add another thick rug on top of another rug because I had no where else to put it and thought it made it a difference. Ever consider adding more to the floor? Also, what are your thoughts on correcting things with Dirac Live vs room treatment. It obviously isn’t as good but Dirac really improved my system. I’m a Home Theater guy and really believe that you should experiment and do as many things correct regarding placement, room treatment etc…. and let things like Dirac do as little as possible and this compromise has kept me happy in my journey. Lots of us can only dream of a setup like yours, well done sir!

Thanks for the quick cuts through the progression of the room. It makes a huge difference when trying to recognize the improvements. Each stage was glaringly different, though I really couldn't hear much change at the end. I will chalk that up to lousy earbuds, and we all know it's way different in the room. But what a bitchin series!!! It has convinced me to take small steps, attacking the most obvious sound issues first, rather than implementing a variety of dressing, in hopes that reducing that issue is enough to be all the change I need. Great stuff, mister!

TBH i never took this channel seriously, but this series on sound improvement has brought me back in.

Kudos to Ron. That’s been the best and most informative series on acoustic room treatment I’ve seen yet on YT.

Agree this last addition, has improved more than expected. Listened from my fullrange Rullit SuperAero 8" (field coil magnets) in a non treated room, but listened at one meter from the opening front horn (azurahorn). Video not to forget, thanks for share!

Yea, the final treatment is amazing. I've got a small room and it's heavily treated. I love it! Thanks for this series - it must have taken forever to film and edit all this. It paid off, this is an awesome outcome.

In the works of adding these things, thanks for all the videos. Inspiring 🥳

Thanks man for open lesson ! Now i understand and hear the importance on room treatment....hello from Romania !

Great work. I completely agree with the angle to correcting our rooms. Have a look a sub placement behind the sweet spot. Solves a lot of standing waves and bass problems.

Big respect to you Ron. The last addition is notisable for sure. Keep it. Speakers are intresting delta in experience.

Ron, this is a great video. Very impressive with your hard work. Great series of vids! Not wearing headphones so I cannot say I hear much of a difference between the two final treatments. Using my TV setup they were pretty similar. My listening room is my living room so I can only go so far. I do have reverb. I just can’t take down my wife’s room decor. She does enable me to put any gear I want in the room and for that I’m immensely grateful.

The room sounds amazing! Great job.

That last step definitely brought the mids and phantom center back to focus.

The final treatment OMG. That was audible difference especially second song. To me using very expensive headphones and Dac i could enjoy it now. Reverb was minimal.

Nice. The added absorption makes everything sout tighter... more controlled.

Great Video and Series. I have been on a similar journey the past 3/4 years but on a smaller scale and budget. Its so addictive : )

That room is friggin epic man. I’m two states over:) The room is everything

Cool vid as always. This makes me want to build a shed out back

This series has been a valuable learning tool for your audience.

Better imaging, better bass. Right on!

This series was great! It was all very clear and practical and it's nice to be able to A/B different spots back to back. :)

What a fantastic series. I think I may use QRD diffusers between my speakers instead of the skyline ones I have now.

Thanks for taking us on your journey. It was extremely informative.

This is the best content i have ever heared for music and hifi. Great work!

I think the final treatment is most noticeable to me in the two vocal tracks. Using the focal bathy. Hearing the profession was great.

Hi Ron… A truly fascinating adventure, watching your journey towards reaching an acoustic listening Nirvana. I’ve become a disciple of your channel and therefore have subscribed. Best wishes KCB.😁👍🇬🇧

I’ve watched you from years from your beginning. And you’ve come along way.. One particular review promoting a sound of a product in a video that had tile floors, tall vaulted ceilings with flat hard walls. And you gave a raving review of the product and the sound quality quality. 😮 my ears were bleeding. 🤣 You’ve learned a lot and you’ve came a long ways. Thank you for your videos you’ve put a lot of work into them. . And you are becoming a master of your craft . 👍

Ron, brilliant work, thank you very much this has been a series of eye-opening videos.

The extra absorption sharpened the focus, also making it easier to hear the recording itself.

Grrrreat job Ron - we learnt a lot from this journey.

Great series! I learned a lot. Now on to what's next!

Thanks for making these series.Nice work! Very pragmatic and inspiring! I had some ideas, but now i heared what these changes independently make. and how to apply them. ok first buy an USB microphone, with long enough cable...and download REW program. 👍

Ron, while I definitely heard the improvements through the original series of treatments, I really could not hear a difference with the last addition. Probably because of the cheap headset I use at work. Props for all the due diligence in creating the "Shed"!!

Fantastic job RON !! GREAT VIDEO !! This is by far the best video on Room Correction influencing the audio reproduction. Pre and post modification comparisons were excellent. While others keep rambling, Ron you did the work and showed us the results. I have been thinking about the room acoustics for a while now. When I buy a house, I will implement what you did. Can’t wait to watch your next video. Great work 🎉

Awesome video! What a great space and I think there is something here for everyone. Thank you!

Thanks for this series and please continue with more advanced topics in the second series. I'm a strong believer in room treatment too 😊

Bravo 👏 outstanding methodology. Thanks for all of your hard work 🙏

Very good series of video. I worked with a small acoustic company last year to measure and propose various solutions. I added Bass traps in the corners and ceiling corners, ceiling traps, diffusers on the side and special curtains to cover the TV. It made a significant difference. It's not cheap but before someone considers a $5,000 equipment upgrade (could be less if you DIY approximately or a lot more...), this makes a very nice improvement even if my room was not nearly as bad as the empty shed. For this video, even through the crappy sound of KZfaq, there seems to be better definition, tighter bass and less echo.

Great video. Better separation between instrument with final treatment, soecially open baffles

Those bass trap benches are a really good idea. I heard the most difference with the ceiling clouds

Been great to follow this journey Ron and I look forward to seeing more of what is to come! I've pretty much just stuck to the "common sense" approach when it comes to furnishing and treating my listening room, but I have to admit I am curious to grab some measurements to see what the room looks like on the computer after watching this series.

It was interesting to hear difference in the completed room. It seems to be the upper midrange wherer I heard the biggest difference. It was more like an open space recording than something in a box. Very interesting. The ability to discern the difference between products you need to take the room out of it!

Holy crap! What a difference! I cannot thank you enough!

The extra treatment makes a noticeable difference, mainly with less bass ringing and more definition to the sound. I hear more of a difference with the box speakers, which is to be expected, but a worthwhile upgrade nonetheless for the OBs. I have also been surprised at how much of a difference those clouds make and will look into this for my own room. Great series!

Ron, Thanks for such comprehensive series about room treatment! Could you list the tracks you used during the test?

16:18 Respect! Thanks for your content Ron.

Dang, you did nailed it, almost, because you might not be done yet, tuning the room. Bring in the guitarist from the beginning and shoot a sound clip! For me, not bias at allllllll. Your best was the XLS encore, that got me into real hifi and questionable questions from wifey about over seas shipment, taxes, toll and VAT. 😅 Love your attitude (John Darko 😂) to all of this.

Wait... Moonrocks shouldn't be your first move???? I thought bedazzled cables was all the room treatment I needed. Thanks for the series!

In my experience, unless you treat the “issues” in your room, the equipment you do purchase can never sound as intended. You will always be chasing the sound you are looking for. There is no perfect solution as each room has its own acoustic properties. This video shows what can be achieved with placement of various diffusion, absorption and bass traps. If you are even halfway handy, You can build most of this yourself and save a ton of money. I’m extremely pleased with the results of the traps and acoustic panels I’ve built for my own listening room. I also built about 40 of them for my church. Made a huge difference. Room treatments SHOULD NOT BE OVERLOOKED. It makes your current equipment sound better.

Very good job. Would be great to see more Acoustic Videos, lookin forward to it. Way more interesting than the 92949 Video on KZfaq about an Speaker. For your room, I personally would recommend you next to build and plan an Double Bass Array for your room to get way more Control over the Lowend. Its little bit more complicated but when its done youve the best way to get control over the lowend. And nice to see you get some PSI's. Would be also great to see a review about their Speakers

The last room modification made a very important improvement in The clarity of the sound, making the listening experience effortless. Especially the female voice is now without boomy resonance and has at last turned bearable to listen to😊

Excellent stuff! Thank you very much for this. I haven't tried this with my hq headphones yet but my first impression is that you might have overdone the absorption on the final treatment.

I can say...putting up even them foam pads all around my walls has made the biggest difference yet..its sapped the power abit it seems but I get zero echo now and everything plays more controlled and more precise

Ron, Indeed these are valuable videos. I would post them again in a year. There are always new music lovers coming. Grtz phil

You're correct. Gear is not everything. The biggest factor in sound is the human listening. From a cheap transistor radio to kit costing hundreds of thousands, the mood of the human is king

Ron, your best video yet!

So true! I remember buying an expensive 5.1 system that sounded amazing at the Bestbuy Magnolia room but then it sounded half as good at home, I was so disappointed and frustrated. It happened again when I purchased a set of stereo speakers for my desk at work, they sounded so damn nice in my cubicle that I decided to take them home and placed them on my glass desk, again, disappointed, the sound was not the same at all. Room acoustics is a priority. 😉👍

This series has been truly excellent. Each step of your journey has shown clear improvements. I know that you have not undertaken this as any form of one-upmanship but I'm still kinda jealous. I have some cracking good kit but my room is far from ideal. My room is quite small but as it's an old 17th century cottage has pretty good absorption in the form of 2' thick walls. Unfortunately the addition of any further room treatment would result in divorce papers. Oh well. The addition of the additional panels made a surprisingly big difference. The vocals seem more focused and the bass more nuanced. There was also a marked reduction in a general hash that eminated from the sides and above. It was one of those things that only became apparent by its removal. Oh. And those Spacials are so much better than the CCS.

You are really impressive and thank you for your honest work and sharing.

amazing dedication & effort to record all these takes at every step & remaining consistent, I wanted to do the same while building my room but It was way too complicated & I constantly had lots of dust so I didn’t dare get my main gear in there. What’s key here is that the room is more important than the gear. I went all out on room design, I have 16inch deep front QRD17 diffusers & 10 inch deep QRD11 on back wall, my floor joists are built on top of acoustic rubber, I have a 2 layer wall with air gap in between. It was an expensive endeavor but any audiophile that listens here is floored including those with speakers the price of my entire setup. My room is actually more expensive than my gear….. for now 😂🤣😂 Bravo again, I’m sure many will understand the importance of room treatment with this series of videos.

Dude, I can hear the improvement with each change, except maybe the benches, with the speakers built in to the iPad. Impressive.

Great demo, thanks for this. Overall on the final treatment did sound better but on some tracks, I think there was a little loss in tone.

The single most important thing in a home theatre/audio space is the ROOM. The most expensive equipment will sound like a cheap unit in a bad room.

It sort of looks like shipping pallets screwed into the wall. The sound improvements were demonstrable. The Spatials exemplify how large drivers make a difference. My room has too many other purposes so I add power and impose a listening zone with a 13 foot listening distance.

Illustrative and informative, thank you for this video! I am looking forward to what comes next. I also would like to ask that, if time and logistics allow, for the possibility of a nearfield desktop (computer desk) analysis down the road. I feel that the practicality and daily consumption of this style of setup is an underserved sector when it comes to data of this granularity. Regardless of the outcome, excellent job!

I noticed that for the ported speaker the previous treatment was better than the final treatment. There was a bass issue that was very noticable. For the open baffle speaker the final treatment was slightly better. The bass issue that was bad for the ported speaker was barely noticable for the open baffle speaker.
