Hi All!! Having read the fascinating thread including the 309 and the XLS200, I am still a bit unsure on which sub to go for. Here's my situation:- System: Avant 906 fronts, matching 905c centre, MS308 sub. I will soon be upgrading to the 903 centres. Yamaha DSP-AX640SE. My room is around the same as Dfour's room (around 3.5 x 4m). My 308 sub is ok but what I need is more power, good punchy low end slam, and good speed. It has to be perfect for movies and music (I listen mainly to dance, house, pop, r&B etc..). All my speakers are in the maple finish. Since I read the What Hifi review on the 309 recently, naturally I have been thinking this is the one for me...but!... Many of you guys seem to like the BK XLS200. I have never rated this maufacturer as, to be honest, other than on here I have not heard of them. Maybe they don't feel they need to have their equipment reviewed in magazines, theyre that good anyway?.. I don't know? Obviously, should this sub be a stronger performer than the 309, I will sacrifice the system consistency and forget the 309. But it would also be nice to keep it all tidy and matched. Having said that, the BK now comes in four different finishes, one of which I think is fairly close to the honey maple. Let me know your thoughts guys, any help greatly appreciated!
