Hello! Thanks to this forum, I got interested in the BK subwoofer XLS200, both for hi-fi and HC, essentially because of its seemingly excellent quality/price ratio. I have some questions related, and I would be glad if someone could answer. 1. How does it compare to some well appraised "udiophile" subs, like MJ ref. 200 or Rel Strata V or Rel Stampede, which are notably more costly? 2. I read that the XLS200 has good frequency response till rather deep tunes. But how about distortion? Is there some measure about its distortion, for instance at 80/90/100 dB and 50/31.5/20 Hz. These are the truly relevant parameters to evaluate the quality of a subwoofer [Velodyne's and SVS seemed to destroy REL's in this department, according to some reports I read]. Is there someone who can help me? Thanks in advance.
