Ok, so I'm finnally gonna buy a sub this week and I'm tending towards the BK XLS200. However, without being able to demo it, I just wanted one last opportunity to get feedback. My room is approx. 6*8 metres. I don't intend to use it in stereo (though it might be a nice option). I won't be going super loud. It also needs to be a fairly small unit. My system is in my sig. The other options were the MJ Accoustics Reference 100 and a REL Quake. How does the BK compare to these? My usual attitude is you get what you pay for - there's a £100 difference so I'm assuming these are marginally better, is this fair? Comments (and reassurance ) would be greatly appreciated! BTW, please don't link to to the budget subs thread: I've read everything under the sun about the XLS!
