Thanks to some excellent recommendations from this forum, I've had a BK XLS200 Mk II (DF, but I doubt that matters) to complement my Arcam Solo and Epos M12.2 speakers for a while now. The sound is excellent and I regard it as money well spent. My problem is that I can't seem to get it set up right, in that occasionally bass voices on the radio come across kind of weird and booming. If I set it so this doesn't happen, I seem to lose a lot of the bass sound. In truth, I know not what I am doing with the many knobs and have settled for "fiddle until it sounds more or less right" using a couple of test albums (Massive Attack's "Mezzanine" and Ani DiFranco's "Little Plastic Castle", in case anyone cares) which both make extensive use of the low end of the frequency spectrum. Is there a more scientific way to do the job?
