Hey! sounds like we both spent a lot of time on the same fence!
You had some of the same concerns that I did on speaker internal crossovers; crossover points AND complexity. I wasen't excited about a crossover right in the middle of the vocal range on the M60, and I liked the x-over set-up on the M50-almost none to speak of! (the 6.5 runs free! It's internally bi-wired!)
You also mentioned something that escaped me til now: and that's how the single 5.25 handles the dynamic information between 200 and 2k compared with how the TWO 6.5s present it.
Hmmmmmmm.....! Good point indeed!!
I was fortunate in one respect though, and that was being extreemly familiar with the sound of the M3; I pretty much knew what to expect. You on the other hand are in the inenviable position of having two long weeks or so to sit and wonder!
Ouch!! That may be worse than sitting on that fence!
Rich.
