In a year or so I plan to buy a house, but for now I've just moved into a duplex. This is the first time I've ever lived in a duplex and I'm not sure what to do with my HT. Out of concern for the guy living in the other half of the duplex, I set my HT (Klipsch ref series and KSW12 sub) into a back bedroom, as far away from his half of the duplex as possible. As it turns out, this room probably could not be worse for HT. The room is very small, square shaped, and has wooden floors (the entire duplex has wood floors) and in it my beloved system now sounds like a cheap radio, the kind your bank might give you for opening a new account. When I use DVDs I'm familiar with to test it, I find that entire sound effects are lost. Just gone. And dialogue, particularly male dialogue, is extremely hard to hear. I've tried treating the room with a carpet (covers about two-thirds of the wood floor) and drapes on the walls, but it hasn't really made much of a difference. I would really like to try building acoustic panels and mounting those on the walls, but my girlfriend is hell-bent against the idea for aesthetic reasons, so I don't know what else I can do. Find some heavier drapes maybe, put a pad under the carpet, I don't know. I'm afraid that without the acoustic panels, the room may simply turn out to be unusable for HT. Which brings me to my BACKUP plan...move the HT into my living room. It's rectangular, and has plenty of furniture, bookshelves and plants, etc, to break up those flat bare walls. But...on the other side of the living room wall is where my neighbor's half of the duplex begins, and I don't want to annoy him with the sound of gunshots and car chases and whatnot...I'm hoping my HT will have a lot more clarity in the living room, which means I will be able to still hear everything clearly while listening to it at a low volume so as not to annoy my neighbor. Is this possible? What about the sub? Even if I turn my system down, there is still the problem of the sub. Since my front speakers are bookshelves, I run everything small and put the bass through the sub, which is downward firing...Even if I lower the overall volume, I fear the sub will be too much. I don't really know my neighbor, but he seems like a nice guy and I plan on talking to him about this, telling him to let me know if the HT is too loud. Problem is people will be polite and then grit their teeth when the sub starts making the floor vibrate, and I don't want to wince every time there is an explosion or a shotgun blast in a movie soundtrack, thinking that it must be driving my neighbor crazy.... Soundproofing the living room is out (for the same reason I can't put panels on the walls). What about reducing the impact of the sub WITHOUT losing overall sound quality? Is that possible? Anyone else been in this situation? Anyone have any advice for me? (besides telling me to move?) All responses will be greatly appreciated!
