Hi guys, first post here. Great forum. I've been reading up here about effects like the DBX 120XP and other subharmonic effects, and the one warning I see is "you'd better have a cabinet that can handle those frequencies". What are some of the cabinets that are especially good for handling these frequencies? Someone gave me a free 2x15 cab with (as yet) unknown speakers. Is the ability to handle the sub frequencies strictly a matter of speaker size (please say yes ) or is it more complicated than that? My current thinking is to maybe have a dedicated sub (hopefully the free 2x15 plays this role) that only gets the DBX, and have a second full range cabinet which is strong on mids (2x10 or 4x10). Is it possible that a cabinet with 10 inch speakers could qualify as one of the cabinets "that can handle those frequencies"? And are there any lower budget cabs in this general category, perhaps? I'm open to all suggestions (including "skip the subharmonic effects" because of expenses or headaches) Thanks!
