I got to demo some at a BB Magnolia a while back.
The 4s on their own were thin in the midrange and a tad bright with too much siblence with music. I demoed them with Sade and some Clutch (nice combo
The 12s were pretty nice. Decent midrange, pretty detailed, overall not bad, but not worth MSRP.
I demoed them against the B&W 683s which had better midrange and highs. The 12s in comparison sounded slightly veiled. Neither had much in the way of bass, IMO.
In the same room were a pair of Deft Tech 8040STs- midrange was very nice, warm and laid back (Sade sounded awesome). Highs were also laid back and warm (a tad too much for my tastes) something that a little treble tweaking could likely fix.
And of course the 8040s had very nice bass response, not muddy or boomy in the least.
The only thing that bothered me was (and it was probably a setup issue) was when they were playing certain parts of different songs it sounded like their was an echo in the room.
Now on to movies. I went to another room where someone else was demoing a Motion 4, motion 8 and motion 2 surround. Here the thin midrange was not an issue and the brightness added a nice (though slightly unrealistic) tingle to the action scenes.
Depending on what price you can get them for the 12s, combined with the 4s and Motion C (I would pay the extra over the 8) and of course a good sub, would make a nice home theater kit.
The 12s combined with a sub would be really nice for music.
