What vintage speaker might you use today

How about a set of Electro-Voice Patricians? Good bandwidth, efficiency and quite revealing.

My 70's Altec A7s were really sweet sounding when used as playback speakers.

I run late 70's Yamaha NS690's in my man-loft system with a museum grade Yamaha CR1020. In my family room I have Ohm Walsh 3's circa mid 80's and frankly couldn't be happier. They are both fullrange speakers that sound good with music or movies, however I've got my eye on Mark and Daniel mini monitors, I like what they do for their size.

Advents, Scotts, and KLH boxes were acoustic suspension, and I miss the sound of that bass. Having bass leak out a port or a passive radiator always seemed kinda sloppy.
