Hi Noel,

I agree with Bridgman on both counts. I'm surprised that Yamaha doesn't give you more options in choosing the crossover frequency. Generally, 80 Hz is considered almost a default setting; and it's what THX specifies.

The 80-Hz crossover betters suits the response curves of the Axiom center channel and surround speakers.
