Recommendations for Vintage Speakers

From your listening tastes, it appears you want a combination of "Punch" and delicacy.  RnR bass, with clean extended treble.   Not an easy accomplishment using vintage speakers.

A budget was not mentioned.

I would recommend:

Larger floorstanding ADS
JBL L110, L112. L150, L220, L300
Polk 10B
AR 11, AR12, AR91, AR92, AR58s ("s" has a dome midrange, other versions do not).   I would stay away from AR3/3/5 series as you will likely burn out the tweeter when listening at realistic levels.

Altec VOT or derivative (if you have the space)

   Hi , my .02 . Hi currently have Klipsch Heresy II’s and JBL 4312a’s . Both are between Lousy and Mediocre. I bought them on a Vintage kick , like you’re doing . The Jbl ‘s Sound pretty decent with about a hundred tube watts per Chanel . One member suggest the Klipsch KLF’s , nice speakers if you brace the cabinets and improve the crossovers . A pair of Tannoys would be fabulous, but expensive. My suggestion would be Bob Crites Cornscalla’s . Large ported cabinet , 15” woofer , and a retro design with a makeover. You could have them in a dark walnut stain with dark blue grill covers . Or do them in a light maple with tan retro tweed cloth grills , or no grills . They would match up well with your amp . BTW , I tried a Sansui 7070, 9090, and a Modwright KWI 200 with both the Heresy’s and the JBL ‘s . My little Klipsch KG 1.5’a sounded sweeter than both ! I recently gave my Marantz 2223 and the KG’s along with a Schiit Bifrost to my son . And the Sansui 7070 and the Heresy’s go  to my daughter next month for her new condo . They’re happy , I’m happy . Now I just need to part with the 4312’s and the 26” Sound Anchor stands I had built . Cheers , Mike .

Haven't read the whole thread, so sorry if this has been suggested already, but how about being inspired by the recommendations of Jeff Day:

I should mention that while you can go balls-out-crazy building exotic versions of high-performance Altec's, you can also get great results at affordable prices too. 

Take for example the Altec A7 Voice of the Theatre loudspeakers, which you can get a beautifully restored pair for around $3500 USD from Gary Fischer, and then have Pete Riggle build a pair of his inexpensive Hiraga-style crossovers for them (around $1000 USD if I remember correctly).

The combination will crush any of the current "high-end" speakers I've heard anywhere near the price, or double the price for that matter, in terms of musicality and the sheer fun factor of their live-like presence, not to mention the personal satisfaction of owning a classic pair of loudspeakers.

I second the snell type A recommendation. Effortless sound that just fills the room in a way I haven’t heard from many speakers. Need a large room.
