D. Rowe - I'd be very interested to hear what you decide to do. I'm running the same speaker set-up as you have with an Outlaw 1050 receiver in a very small room. I'd sure like to know what differences you notice in going to either more power or a separate sub (or both!).

If you think of it, please post a follow up. I can't offer much input on wiring or cross-over settings - I just haven't had time to experiment.
