Re: Stereo subs - Do they rock or is it overkill?
You can split the sub output or some subs can be daisy chained together. Posititoning two subs gets tricky as you have to do each one separately, then balance them together. Two subs adds a smoother fill and lets each sub work less for the same output, this may not be necessary depending on the sub you use. Four subs is likely the best if you and your room can handle it, but the logistics of this can be hairy.
I am currently waiting on four of the new Def Tech Mythos ST's, each with a powered sub in them so soon I will have four subs in my maiin rig and will try to post on them as I work through the review.
