I thought about starting a new thread, but I'd rather hijack this one.

Regarding these pro-amps (whether the Behringer, QSC, Crown, etc.)...

Since I already have a BFD and since my Onkyo 805 has all that groovy processing, what would be the downside of using something like this as a subwoofer amp instead of using the more common plate-mounted, sub specific amps?

If I was, you know, hypothetically interested in adding a DIY sub or something.
