I always wanted to like Klipsch speakers but could never quite get there. I've heard. Chorus, Forte, Belles and the K Horn, their flagship. I heard rock music through the K-Horn (your interest) back in '83 at a hi-fi shop. Not impressed. Folks here who mate a sub to their Ks know what they're talking about, because Ks standing alone won't produce the sort of bass your son appears to want.
