Brian Q. ★★★★★ Oct 13, 2026

I was worried in-wall speakers would sound thin, but these are THX SELECT2 certified and it shows—dialogue stays locked to the screen even when I'm sitting off to the side. The Uni-Q array really does keep the sweet spot wide across the whole couch.

Scarlett ★★★★★ Oct 12, 2026

The Uni-Q driver really does something special with dialogue — voices sit dead center even when I'm off to the side of the couch. Running these as my surrounds with a THX-rated setup, and movie nights finally sound like the theater.

Installing these was straightforward, and the THX SELECT2 certification gives me confidence for home cinema. The imaging from the Uni-Q array is incredibly precise.
