Uhmmm...the 8" drivers would indeed be most excellent for a larger room. Sorry but even the triple 6.5" HP drivers can't pump it up in my 4,200 cu. ft. room. The living room is a different story. So yeah...triple 8 inchers all the way. Slimpikins has his Model T signatures fed with Anthem M1 2000W amps off a separate power panel and they rock his 'nads in his 10,000 cu. ft.+ space.
Now I'm not complaining because my multiple sealed subs offer an impeccably articulate and dynamic bass. The bass in my main room is now superior to the ungodly bass offered by just the actives in my living room. It took money and work though.
The problem with a wider cabinet is diffraction. As for 8" woofers, not sure Axiom can provide that on Axiom speakers. There has to be differentiation between Bryston and Axiom. The immediate, visible difference is the driver size.
