Recommendations for Vintage Speakers

I’m currently looking to put together a vintage system and am wondering what a good pair of full range, floor standing speakers would be. They would be powered by a Pioneer SX-1250. I listen to a very wide range of music, a lot of live Grateful Dead, Classic Rock, Metal, But also enjoy Jazz and even a little Big Band music once in a while. Thanks for your help!
If you keep an eye on the outlet store link on vintage OHM models refurbed with new components regularly come up for sake there for about the same as original cost. Or if you contact OHM there may be others available not posted. Or if you pick up a vintage pair of OHMs elsewhere on the cheap, they provide upgrades and service still for most every model ever made.
ADS or Celestion Ditton 33/66 speakers for lower cost options -great for rock and metal.  
Allison Model One
Celestion SL700 - although they are stand mounts and not quite full-range
FWIW, I owned an SX-1250 back in the day (Bought, brand new @Best Products in Houston, TX in 1977.).  I acquired the receiver as the first piece of a system I was building, so auditioning a lot of speakers-from-that-era was next on the agenda.  Aside from a brief flirtation with Bose 901 series IIIs, the three finalists from a summer’s worth of haunting Houston stereo shops (of which there were many at that time) were the JBL L-100, the JBL L-65, and the Pioneer HPM 100.  At that time, there was usually an SX-1250 or 1050 in stock and set up at these venues so that was a plus.....I wound up with the L-65s and are still listening to them daily.  Such great sound and so “of those times”, stylistically!  (I”m running them with a PrimaLuna Prologue Classic now.). One bit of info might be useful...I really had my heart set on the big Infinity.Quantum Series speaker’s.  I had salesperson after salesperson steer me away from them because, as they would tell me time and again, my “monster receiver”didn’t have the steam for anything bigger than the Quantum 4 and even that pairing was marginal.  I thought that it was as simple as “The world's Most powerful receiver is gonna be the perfect match for those badass QLS-1s.”  What can I say...I was 18 with too much pocket change!  Glad I got talked out of that one...
