This is a real question, I have just bought the following: B&W VM1's B&W ASW675 and to be honest the base is a little scary. Makes the house shake and can feel it in my chest!! Sounds great but I am not sure if this sub is to much for my room size (12ft x 18ft). Unfortunately in the real world sound levels need to be kept to a reasonable level!! I am not sure if I have the setting wrong but I took some advice from the guy at the place I bought it and have the setting fairly low?? Any thoughts??
