There's a number of easy answers to your question (in no particular order):
Altec Model 19
Altec 604-8K
Tannoy System 15 DMT II
All are high sensitivity (95+ dB) with easy impedance curves.
I use the latter two. I prefer low- or zero-feedback MOSFET amps, but they'll work with most anything from 300B and up (powerwise).
Hope this helps.

Joel.
