I had an earlier version of one of SVS's cylinder subs. It was OK, but I couldn't get past how big and ugly it was. I prefer sealed subs. Unless footprint is really an issue, I'd look at one of SVS sealed subs, better yet, get at least 2, preferably 4. For music, I'd look at Rythmik first. For sheer output, take a look at Power Sound Audio (started by one of the founders of SVS).
