People have touched on the subject but have not asked the direct questions.
If you provide an answer to these questions, maybe you will get a response that will narrow things down a bit.
Mind you, all of the recommendations are good.
How large is your listening room?
What type of music do you like?
Do you like it loud or at lower listening levels?
What type of amp/receiver, turntable or cd player or other source do you have?
THE best thing about vintage speakers is that you can experiment like crazy and for the most part, you can sell them at, near or above what you paid for them so it's basically a rental program until you settle down with keepers.
This to me is the best site to ask these questions as people here are great. But help us help you by answering these questions.
Prices do vary greatly by location. I see posts here that I just drool over the prices some people are able to get things at as my market is more expensive.
So don't think that all the prices mentioned here are gospel as it varies wildly depending on your local market.
Good luck.
