Upgrade-itice strikes yet again, beckoning me once more to her warm embrace. Never really happy with the Wharfedale SW150 subwoofer. It made low level noise, but was never really controlled and got a bit too boomy. With music I found it unusable. The low level drone just cancelled out the listen pleasure for vinyl and CD. The lower compression of streaming suffered even more. SW150 was boxed up and sold on a forum I frequent. After living sub--less for a couple of weeks I gave in and purchased this beauty: A BK Gemini II in light oak. I mean, look at it, it is lovely just to look at. Still breaking it in, but the low level experience is in another league. So much tighter, and musical. When listening to music it is a world of difference, and with films, the gut punch is more than enough. I only have a small listening room, and the reason I went for this entry level sub is I just don't need anymore at present.
