Now I have my new sub I'd like to pick the brain of past and present owners of the B&W ASW-675 if I may. The sub has two EQ settings. A, which is supposedly optimized for home cinema use and generally louder. B, producing lower extension and tighter bass, supposedly better for a music setup. I've tried both and so far I've not identified any dramatic differences, but something is saying to me that the B setting would be the better option, not A as the manual suggests. Past and present owners, which did you find gave the ideal movie setting?
