RE: Suggestions for Closed-back 212 Fender Supersonic cab

I plan to use a Fender Supersonic 212 Cab (closed-back) with different heads/ combos, i.e. Marshall to Fender type tones.  Can you suggest the most versatile combination set of speakers for an insulated closed-back cab? I was thinking of ET-65 & Retro-30, but might want to wait for the new ET-65 heavy magnet speaker? Versatility is the main consideration for this 212 cab. Currently the cab has two Vintage 30's.

Thanks for your help,

Stephen.

Might be worth the wait ... I need to nail down Dean on a date!!  The difference would be that the Heavy ET would be more predominate in the blend.  The ET is a very warm & vintage sounding speaker.  If that's what you want more of ...
