Hey all, I've decided that I need to get a small sub to augment my standmounters for my bedroom. The system is currently a pair of Usher S-520's which are bi-amped using a Linn Classik and an LK85. The Usher's are fantastic but they roll off at about 52Hz and I really notice the lacking information on a few pieces I listen to (jazz with a double bass for example just sounds empty at the bottom). I will not be listening at reference levels and it doesn't need to pressurise the room like an HT setup. I'm looking for something fast and accurate that will keep up with the mains. So far I've been considering the BK Gemini but am not sure if I'd benefit from, or in fact need to, step up a level. I have an SVS SB12+ in my HT system so will be giving that a go this afternoon. I don't really want to have to drop £500 on another one so would appreciate any thoughts from Gemini owners. My room is a funny thing because it's an extension on the back of the house. It's more like two rooms stuck together with a wide doorway linking them. The main room is about 4m*2.7m and the smaller second area is 2.8*2.1m. The ceiling is 2.4m which gives a total volume of 40m^3 or 1400ft^3. One last question. In a music only setup what is the best method of hooking up a sub? High or low level inputs? Thanks.
