I had a few thoughts. It keeps all the speakers the same across the front (although this can be done with other models). It would also look even and having three 5 1/4 drivers I felt would give the best impact. I will be using two subs when I'm done to fill in the bass portion. I've also considered all M22's or M3's, but I'm worried I'll be disappointed. My front speakers now are outdated and were never high quality but all the driver's are large (2-6.5's in the center, 1-6.5 and 2-12's per left and right). While they may not be tops in quality they definitely supply quantity. The room I have is about 4000 cu ft and opens into a hall and kitchen.

I should also add this is on wall or on wall/ in wall. Right now I'm looking at removing towers from my setup.

Thanks Mike
