Mark,
I have already seen your, um, 'ported' rear. No need to repost! ;o) ANd as was mentioned before, PLEASE do not post your front (this is a family thread;o).

Watching Wall-E yesterday was great. It had a lot of extended 7.l tracks to be able to move around the room to see how well my current small bookshelves filled the rear space. Specs wise thes Bic V52's are very similar to the M2's, except V52's have a smaller twtr at 1/2" (vs. 1").
Audyssey on my Denon 1909 had set:
FL +6; FR +5.5; C +4.5; SW +3; SL +6; SR +6.5
SBL +4.5dB; SBR +6.0
The backs were weak at list. pos. at this setting.

To keep the same balance between L&R, I raised both by +6dB to max (for SBR):
SBL +10.5; SBR +12

As mentioned earlier, this felt like it 'almost, but not quite' enveloped the list. pos. from the rear.

In your opinion, (if I am not able to upgrade to your 'rears'), the upgrade to the following would be marginally better by?:
M2's?
M22's (on sides)?
VP100's (oem x-over at 2.7kHz)?
VP100's (∆ to M22's 3.5kHz x-over a no go per Brent at Axiom)*

*I heard back from Brent at Axiom.
