Adrian, i have read about others using M22 as a center. This may be the best solution for me.
@Dakkon, I do have a "big" sub with the PB12NSD but want BIGGER for the same reason someone buys a corvette and never goes above 70 MPH.
While the SVS sub does way more than it should for only costing me 600 bucks at the time, i feel i have a week spot in the say 60-80 hz level while using M22's as fronts. This would be the reason for going to M80's. I would probably set a crossover at 60 hz and let the SVS just pound away at 18-60 hz range which it does oh so well.
I appreciate all the feedback and when it comes down to it i feel a VP160 and M80's will be the future for me, now its time to tell the wife. Wish me luck
