I am attracted to a system comprised of L, R and a Center channel only. A subwoofer is a definite "maybe" at some time in the future, but more likely not.

Intelligibility of center channel dialogue seems lacking with my present set up which is M22 On-Wall for L&R plus a VP100 for the center.
The receiver is old but is in perfect working order and has adequate power with 100 watts/ch. But, the owner's manual clearly states
CAUTION
Use speakers with the SPEAKER IMPEDANCE indicated by the speaker terminals"


Those terminals are, needless to say, labeled 8-16 ohms.

So, it seems clear. Not recommended. Even forbidden!

I'd like to use M80 On-Wall and a VP180 without buying a new receiver, but . . .
What would the most economical receiver be that can safely handle these 4 ohm Axioms? I am not concerned with extreme SPLs in my living room.
