My treaments, suggestions for others with and without....
I’m fortunate enough to have a dedicated room for my home theater setup. I have mulitple DIY acoustic panels on the back wall behind my subwoofer and front soundstage, covering approximately 2/3s of the wall. In addition to this, I have a couple of DIY acoustic panels on the left wall facing the front while the right front side is partially open to the other half of a finished basement.
Some options I would like to be able to incorporate would be bass traps for the corners of my room, however all of the non-DIY available options are priced out of my reach at this point in time. I'd also like to see someone offer an acoustic treatment panel that can be swapped out for existing drop ceiling panels (2x2 and 2x4). Most of the 2x2 or 2x4 panels on the market at this time are far to sizable and heavy to use in this scenario.
I can honestly say the treatments I’m using provide a substantially positive impact on the acoustics of the room. While the listening area wasn’t terribly harsh to begin with, the accuracy and placement of instruments for musical listening was noticably improved as well as the accuracy of dialogue for movies, even with lower listening levels or quiet dialogue.
For those that question the validity of acoustic treatments, I strongly urge you to try and incorporate acoustic panels or at the very least, simple room treatments that can soften the room with a tapestry or two. Even the introduction of decent carpeting and plush furniture can help with secondary reflection points to help “clean up” the soundstage on the whole.
These last few suggestions are good options for those that aren’t able to incorporate dedicated acoustic treatments due to room size, aesthetics, WAF, etc. Any objects in the path of the listening area as well as the room construction and design can significantly impact the sonic signature. If you’re fortunate enough to have a room that provides very little in the way of secondary reflections, consider yourself lucky as you’re likely in the minority. If you’re not sure, try some of these suggestions to see if it helps. Remember, just because it works for someone else, it doesn’t mean it will necessarily work for you, so experiment and see what works best for you... -TD
