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!
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...
I'd look for vintage Polk in the SRS-SDA series. They were remarkable in my vintage system. Sorry I let them go.
I have a friend of mine who I call "Vintage Joe".  He has had all of the above mentioned speakers.  Depending on your price range and room size the best speakers I heard from his system was the IMF 50s and up.  Large box style floor standers.  I also agree with KEF 104/2s and 105s and Dahlquist DQ-20i's.
