I currently have a REL strata II and REL Q-bass 50, which is a (surprisingly) superb combo in my set-up. I'm curious to know if a single velodyne CHT-15 would outperform my duo of RELS? Would it go deeper, be punchier etc? I find my system sounds great as it is, and the REL combo gives a smooth bass, although not always as "tight" as it could be. Whilst I am happy with it....I want something which will give an altogether deeper sound. It's a difficult one to judge, as I can't get a demo anywhere (but read that the velodyne rocks from people on this forum), and you can't compare the new RELs with the old Any advice?
