Hi everyone, I'm new here, and I need some help. I recently purchased a floor model of a Sony DAV-HDX275 home theater system to replace my 15 year-old (and failing) Sony bookshelf stereo. I had very little money to spend, and I decided to go with the home theater because bookshelf systems have basically turned into glorified boomboxes, and I thought the DAV-HDX275 would be more versatile as far as being able to keep using it as an amplifier when the DVD player inevitably craps out. Plus, it was a great deal. I tested it out at the store before I bought it (granted, at a relatively low volume - probably a mistake), and I thought it sounded pretty good for what it was, even though it has no equalization to speak of and very few sound options. I got the thing home and set it up. It's working fine, but my problem is this: the subwoofer is kind of overwhelming when I listen to music with a lot of bass (when I listen to jazz or acoustic music, I think it sounds fantastic). I originally had the subwoofer sitting on the bottom shelf of my entertainment center, but I thought the vibrations might be amplifying the bass excessively, so I moved it to the carpeted floor next to the entertainment center. It seems a bit better, but it's still overwhelming to my ears. Is there anything I can do to attenuate the sound coming from the subwoofer? I suppose I could start listening to jazz exclusively, but as much as I love jazz, I want to rock out now and then without rupturing my eardrums! I hope I haven't made a terrible mistake. Any advice would be appreciated. Thanks!
