Ref Center Channels:

Check out recent third post here.

Interestingly, I don't remember Axiom 'promoting' dual center channels. This was discussed 10 years ago & the gist of the conversation was to try it if you want to experiment - like many do in this pastime.

Dual center channels being 'recommended' by Axiom was not their normal policy that I can recall. Perfectly reasonable advice IMO.
