Pfarinelli Posted May 30, 2016 Share Posted May 30, 2016 Does anyone have experience with acoustic room treatments? The room is very hard. The only sound absorption is a carpeted floor, leather theater seating and a few large decorative pillows about the room. My theater area is a 20'x19.5' loft. The right side is open with a railing. There are 4 large windows. 1 window behind the right and left floorstanders. Left wall has the other 2 windows. I am replacing the faux wood blinds with cloth cellular window coverings today. I believe they will help a lot. What else can I do to calm the room down? How do you figure out where to place additional treatments? I have RP-280f mains. 450 center and the 115 sub. I have mordant short carnival 3's for surrounds and rears. Thanks in advance for your advice. Quote Link to comment Share on other sites More sharing options...
Paducah Home Theater Posted May 30, 2016 Share Posted May 30, 2016 Panels of insulation at the first reflection points helps a ton. Get the sides for sure but also the back wall if you can. Since the room is open on one side, you'll have to concentrate on taming the other. Ceilings aren't that important with horns that limit vertical dispersion. If you have to rely on drapes, get the super heavy commercial stuff like from Rose Brand. Owens Corning 703, Knauf black acoustical board, Roxul rock board, lots of choices. Diy is fun, most commercial offerings are too expensive but there's a couple that are affordable, I'd have to Google it, forget the names. If you really get into it, you can measure with REW and produce waterfall graphs to fine tune it, that's how you really know where to put them, but first reflection points are the biggest. 1 Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted May 30, 2016 Moderators Share Posted May 30, 2016 That's what I did. I placed mine at the first reflection points and then added others in the room aesthetically. It added a lot of clarity to my room because I had a huge slap echo 1 Quote Link to comment Share on other sites More sharing options...

Get the sides for sure but also the back wall if you can. i had a very long conversation on the phone the other day with a very knowledgable acoustics guy. first reflections points was always told to me as being the first thing to treat and if only thing you could, well that would help alot. he said that is not right. and also said some very interesting things about toeing speakers in as well. fun to learn from very knowledgeable guys.

Floyd Toole started this idea, and lots of people like to parrot him. Just saying. The guys who do the parroting can come up with some weird ideas. Thought you were part of the conversation with the Audioholics guys that showed this. Watch starting at 3:30 to see where the recent conversations came from. I can't say that I'm in agreement with Gene when it comes to clarity in a home theater. Ask Eithan Winer if he agrees with this. Mark Seaton has went on record saying that he has witnessed reflections accounting for a perceived 20 db boost due to the time smears involved... would anybody really think that this is a good thing? Taming these reflections are always in your best interest in terms of things like dialogue intelligibility as far as I'm concerned. I imagine that some musical tracks can sound more interesting without doing so though.
