I'm about to start construction on house that's going to have a home theater in it for a client of mine, thanks for doing this video very timely.
-
If I hear: "uh-huh" one more time. I'm going to scream.

Couple small rugs, entire back wall is heavy floor to ceiling drapes

Brilliant content 👍🏼👍🏼

For room correction, I hung 34 blackout drapery panels around my 14.5' W x 19' L room. Very minimal reflections. I have a 7.1.4 system. Yamaha RX-Z11 receiver. One sub & one I-Beam VT-300 transducer in my seating platform riser.

Great advice, thanks! A noticeable improvement in my sub setup was made by raising them off the floor. Mounted on 400mm mdf plinths, separated by some IsoaCoustics pucks. Some Sorbothane isolation pads will save people the price of the pucks. (Put a bit of cloth between the Sorbothane and the sub! It's a bit tacky.) It was suggested that if I get some spare time to try the pressure effect of mounting them at different heights or each at different heights. I lined the inside of stands with 25mm opencell foam, then filled them with .activated carbon pellets. I don't know what difference that made. Hide some castors under them so you can move them around If your only using two at the front tune their volumes for a stereo imaging effect like your main speakers.

‘A few hundred dollars’….. 😂…. Have you seen the price of the stuff we need 😮

I’m looking for some ideas or suggestions with a home theatre with 1 open wall. Open to another part of my basement. How does this affect my sound, do I need any additional treatments for that side of the room. Thank you.

Thanks for the acoustic treatment video series. Will you make a video where you can see the acoustic measurements of the Two-Channel Room and Home Theater ? It is to see your TR (T20, T30, Topt), Waterfall.ETC Written with Google translator. Greetings

Excellent video gentlemen and so informative. Thanks for doing. I have a roughly 11ft wide by 14ft deep dedicated 7.2.4 theater room that was built in our garage. One of my first reflection points is right on our solid wood core entry door to the room. I also have B&W 803 D3's for mains. Is there any value in putting absorption/diffusor or a combination of both acoustic panels directly adjacent to the 803's on the side walls? I have reached out to GIK and Vicoustics for options, proposals and wanted to hear what you guys think as well.

What is the model number of the Polk subwoofers your is subwoofers you're using
-
Question, would acoustic treatments or base management be needed for an open room with a large window that is 24 ft long by 17 ft wide

up to 19:22 good points, now here is where the tires hit the road... Ok I stopped at 20:50, why? Complete nonsense sadly. The 1st thing one needs to do is find out what and where their problems are an they are always with noise floor, secondly with frequencies below 300Hz, and then 1st reflections. Note: after each step measurements and adjustments must be made... If using Rock Wool, Fiberglass, and even foam (I never in my career as an acoustician use the first two) one must have loads of experience in placement and sizing as these materials can smear and muddy midrange. The other issue is they have a narrow frequency range with unpredictable rate and level ratios. 26:58 in... OK, you guys are just spinning more BS by trying to validate the industries obsession with room corners (corners are at best only responsible for about 16% of low frequency issues)!!! These so called experts should know better as it's parallel surfaces not corners!! Note: Never put a Sub in a corner!!!!!!!!!!!!!

It's really sad that this video was posted 2 years ago, according to YouTube, but these guys couldn't take the time to respond to a single comment/question in all of that time. And, as of this comment, there were only 14 other comments, so it's not like it would've taken any more than ten whole minutes to do so. These guys must really care about their current and prospective customers.
