The good news for me is that my girlfriend has finally allowed me to use an entire room dedicated only to HT in the new duplex we just rented. The BAD news is how my previously decent sounding HT, sounds INSIDE the new room. I knew that room acoustics played a large part in overall sound quality, but I never knew HOW large a part they played. My system was essentially UNlistenable. Just awful. Movies sounded like they were coming out of a cheap transistor radio. Flat, harsh, tinny and echoey are a few of the descriptions that come to mind. (Of course my girlfriend insisted she couldn't tell the difference.) The room has hardwood floors, and is square-shaped (though not a perfect square). It is also pretty small. Obviously this is not the perfect room to start with, but I don't have any other choice right now. First thing I did was to put a carpet down in the room, which has helped a lot. I also tacked a blanket up over the back wall, to try to absorb some of the sound coming from the front speakers. The blanket is only a temporary solution, as I promised my girlfriend I would find something more aesthetically pleasing to replace it with ASAP. I think what I need is some kind of material to mount on all four walls to absorb some of the sound. (I believe this is called baffling?) But I can't afford the professional home theater stuff sold specifically for this purpose. Are there any cheap alternatives out there? When we actually buy a house I'm going to aim a little higher, but for right now all I want is something I can mount on the walls that will absorb sound without looking too ugly. Any suggestions - as well as tips for making the room more HT friendly - would be greatly appreciated!
