What Are Good Objects/stuff To Reflect Sound Waves From Home Theater Speakers To Improve Sound Quality?
I am wondering, what should you do to improve a home theater sound/speaker system for more quality and surround sound experience . So what im asking is whats the best things to put in your basement to reflect sound better for surround sound experiences. I have hardwood floors, wide open area, a big theater couch and layers of paint on drywall if that helps reflect sound waves. thanks for your time.
First there are many misconceptions about acoustics, one is that you want a damped or (dead) room. You want refections but you want them to be controled to a ideal time delay usually about 1 to 1.5 miliseconds.
You are starting with what sounds like a nice room. You will want to add as little sound absorbing material as possible, I would suggest using a area rug on your floor, you will want to treat your back wall behind the listener and careful placement of material on the side walls.
I prefer to use defusion rather than obsorbtion material, being that the problem with material that obsorbs sound is that they do not do so in a linear fashion. Meaning it may reflect certain frequencys and absorb others, this can and will call whats called Comb filtering.
Speaker setup and dealing with Acoustic treatment is a very complex and time consuming process to do it right, but with some patience and good information you can achieve good sound.
I would be happy to go into greater detail of speaker placement and acoustic with you if your interested or i would suggest a book called. The complete Guide to Hi-end audio (by Robert Harley) which gives you a pretty good idea of speaker placment and acoustic room treatment.

Egg crate foam. It’s cheap and easy to install. http://www.amazon.com/EggCrate-Foam-Mattress-Pad-Thickness/dp/B0002Q0VD8

Rugs;tapestries; curtains carpet under lay;..foam rubber; acoustic foam, sonic barrier (that’s a name brand) also cascade makes stuff you can use…early reflections are more damaging to sound quality than late reflection, which means the closer the reflection is to the speaker the more critical it is to treat.

I have to agree with Kevin.
Your main speakers are called ‘direct radiators’ – you dont want reflections.
Try this: sit in your main seating position and have someone move a mirror around the walls and floor. When you can see the tweeters of the speakers in the mirror – mark these spots with a post it.
Now you know all the spots in the room where reflections will cause problems. You want to put absorbers, fabric, blankets, rugs, etc. in these sensitive spots. You can absorb or diffuse the sound – but these are the spots to do it from.
