M80's and will provide the best smooth sound spread across the front soundstage. This is extremely important in multi-channel sound whether it is music or HT.

Next get yourself a pair of Axiom QS8's for the surrounds. Axiom calls their design "quadpolar" and they are an amazingly good surround speaker and again are perfectly matched with the M80's.

Doesn't make any difference how good the indiviual speakers are if they have a different sound profile. In a 5.1 or 7.1 system ALL the speakers should be as closely voice/timbre matched as possible. This makes a clearly audible improvment. Decide on the left and right if you will and then add the center and surrounds from the same brand and series.

This point cannot be overstated. There was a time during the original ProLogic days when we could throw together a dog's breakfast of speakers and it would work passably well. Those days are behind us.

Modern multichannel sound demands a greater degree of timbre matching and overall output from all speakers. In the beginning, you need to use what you've got, of course, but the goal should be to move toward similarly voiced speakers from the same model line. This will provide the most stable soundstage and seamless transitions.

As you get a chance over time to consolidate your system, you'll be even more appreciative of the wonders of multichannel sound. Good luck!
