If you are going to switch to something like the P880, I would suggest as some of the others have done and simply go with a fully active 2-way frontstage. If you like the tweeters, ditch the mids and go active with something like the AA Polys.
That's plenty. My amp is rated 60wpc and gain is up mabye 1/2 way. I run the Vifa tweeters from AA. The Logic xt25 I believe.
I don't seem to notice any phase/imaging issues with 2 mids per side. Maybe I'm too busy noticing the incredible clarity and fullness of kickdrums lately... //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
