Hey guys, thought I'd get some feedback from the gang on potential driver choices for a major upgrade to my buddy's HT, featuring the quartet of RSS390HF subs behind his front row.

I've talked him in to going to pro style drivers to increase sensitivity so that his new 9.1 receiver (130W/ch) won't need any augmentation.

To start off, I think I've convinced him to go with the Aurum Cantus AST30100 for the top end. For the low end, either the Eminence Kappalite 3012HO or Deltalite 2512, with 200Hz sensitivity ratings around 97dB. I'd like to use a 6.5" pro mid, to provide the best power response possible for a crossover to the AC AST around 1200Hz LR4. That said, there are a few candidates to consider, but I'm totally ignorant on their potential quality of sound.

Anyone with any thoughts on the B&C 6PEV13 or 6MD38? Looking for a mid with sensitivity in the 95dB+ range, so any suggestions other than these B&C would be appreciated. I'd rather stay away from sealed back mids so that I can have more flexibility in where it crosses to the woofer.

These will be in-wall 3-ways, so no baffle step compensation will be required.
