I would like to find a subwoofer that has a good high extension (and at least down to 25hz), that would better complement the on-wall M22's since it seems the low extension of the on-walls is not as good as the bookshelf M22. But I would like to be able to adjust this away, a little at a time, to where I really need it, which is something I don't know at this point in time. The PB12-NSD goes from 20 hz to 410 hz in nearly a straight line. But the amp only has a high cross-over at 120 hz which IMO would only allow you to have up to 20-120. Not something like 20-250, or 20-300. Is this correct, or am I missing something?
