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!
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!
