Axiom Home Page Forums General Discussion Advice from Axiom Owners M80 in huge, untreated room, corner placement?

That QSC should give you enough power to listen comfortably, from outside, with the windows closed, from the far side of your neighbours yard...

I think you will be very happy with the M80s.

Edit: for what its worth, I was playing with a power calculator and it looks like 68-70w will do you if you want to hit peaks of 90 db at the listening position. If you like crazy loud, 95 db pushes that up to somewhere around 150w.
