Where did you get speaker cloth from? What price? Please share. Drop ceiling with speaker cloth seems to be super great acoustic treatment idea. It may realy look like lack of power or just speaker limitations.
Marakanetz,The cloth can be had at any fabric shop.In my area there's one called Joann fabric'...As in your comment to my thread It's going to be hard to get more Power unless I move to the 1000 watt monos I whould think 600 should be enough.My speakers are full range and go way low..I heard these in another room with what I would say was subterranean bass....but not in my room..
Usually containing the bass in the room is the opposite of what you want, unless you're concerned about disturbing the neighbors. The reason for this is that it reflects around inside the room which acts like an organ pipe, giving you peaks and dips at various frequencies. So while keeping the bass in the room will increase bass levels at some frequencies, it will decrease it at others and give you time smear, pitch shift, and one-note bass.
So I'd look for other solutions, which could include new speakers, subs, or a bit of EQ (so as not to overdrive the woofers or amp). Also, if your room is too live, you adding some mid/hi frequency room treatment might improve balance by bringing those frequencies down some.
Dunno, bass varies tremendously as you and the speakers move/are moved around the room. Rooms also vary tremendously in the frequencies at which they support or cancel bass depending mostly on their dimensions. Have you tried the old trick of putting a speaker in your listening seat and then crawling around to find the point at which the bass sounds best? Then try putting the speakers there.
