I moved from the lower model Klipsch 20 series {B20,C20 etc.}
Found I didn't enjoy the treble they produced found it to harsh and sibilant. Then I moved to the M3 and never went back, size pretty much identical to the B20. Now have all Axioms. M80, Vp160,M3,M22 and Qs10a.

As Alan said the VP150 would do much better being swapped to something larger. As most movies including Atmos are mostly center oriented.

Congrats and welcome
