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!
The Bozak LS-400 and CS-501A are true floor standers that sound very good with all types of music, even though Rudy Bozak was a classical fan.  Tannoy is another excellent vintage speaker to search for.  Actually their present day Prestige series of speakers have a vintage look, so you could have a new speaker having the proper appearance for your system.  It's not a floor stander, but the AR-LST is also an excellent vintage speaker, however they are not found used very often.  Have fun in your search!

Budget?  How vintage is vintage?

Some original B&W 801's?

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
