Not so fast. Just hang on to them for a bit. Sure, you have a sea change in LF, ok, good. Now, just wait a bit, then after you have had a nice long run with the new speakers, roll in the subs ever so slightly, very lightly. You'll see that actually, one can often not have enough 15" woofers.
I make systems with varying numbers of 15" woofers, from none, to one dozen. Yes, that's right, one dozen 15" woofers. There are fundamental things that happen with LOTS of cone surface that simply cannot happen with less cone surface. The sheer EASE of many big bass drivers is unparalleled, and I DO mean Unparalleled.
So, you have them paid for, sitting there; just put them off to the side for a bit, then do a bit of experimenting. Nothing much to lose, and potentially a lot to gain. No, using the subs with the new speakers will not be as perfectly clean in the LF, but it can be superior in several other aspects. You'll see, if you wish. It's all a carnival of changes.
