Well I got that old switch up itch, y'all know the one I'm talking about. As I have stated many times before, simply lovin my dc lvl 4 twelve, but I happen to have a couple of re se 10's laying around doing nothing what so ever. How big a diff, if any could I expect on the se's ported. And, what freq could I tune at with subs that have an fs of about 26hrtz? Of course on my saz1500v3. The se's are the last series with the 12 spoke grey basket. Thanx up front.
