C'mon guys, I know a few of you have this sub... what's the verdict? Is there a sub it's most comparable with? Did Bertha get rid of the hum? Should I order one? My Ruark Talisman's are crumbling when sent too much bass in movies, to the point where they're almost rattling, (not always, just when it gets bassy and the volume's up to about half way via a Yamaha RX-V795a amp) and I'm in need of an outlet to help them out. The BK XLS 200 looks ideal, I'm just not brave enough to chuck money at it without some kind of feedback from you guys.
