I have 3
Aperion Audio 422c Centers as my L/C/R, with Boston 465 in-ceiling speakers as the rear surrounds in my 7.1 system. For home theater, they sound fantastic. for 2.1 channel music, they sound very detailed. In my office (which is an acoustically treated audio edit suite), they sound amazing. At home, with a hard wood floor and no rug, plus windows, they're a tad sibilant.
As far a cohesion, they have a unified sound. Bonus points for build quality and customer service. These are not much bigger than some of the larger satellite speakers out there, but look REALLY good and not plasticky.
