Axiom Home Page Forums General Discussion Home Theater Need Help deciding on 'Stealth' system

I'm in need of some serious help deciding on what speaker system I should purchase for my complete HT upgrade. The 'boss' (or SWMBO) doesn't want large speakers in the living room cluttering things up so I need to consider a stealth installation. This setup will be mostly used for movies but will occasionally used for music (80% vs. 20%). So far, I've decided on the TV and receiver... the Panasonic TH-50PX500U Plasma and the Denon AVR-3806.
I'm struggling with the speaker set up for this 7.1 system. I've been considering using in-wall speakers but I just discovered the Axiom Architectural Series and they look very intriging and may get the stamp of approval from the boss.

Could someone provide me with some good rationale why an in-wall speakers setup would not be as good as the W3, W22, and W150s?

I have been considering Mordaunt-Short speakers for the in-walls (and/or maybe Polks) until I saw these new Axioms.

Thanks in advance for the advice.
