It's too bad the OP hasn't been back to clarify his needs and share his location. There have been some really great recommendations in this thread, but ultimate, I think it comes down to what's available locally, what exactly the OP means by floor speakers and vintage, what he's going to be driving them with, how much he cares about cosmetic condition, and if he's willing and able to perform basic repairs (refoam and recap), or if he expects someone else to have already done this work.
I have/had several of the speakers mentioned and paid less than $300 for each (KEF 104/2, Infinity Qb, Klipsch KG4, Rectilinear Highboys, KLF Model 23, etc.), but most needed some kind of work (cosmetic refinish/repair, refoam, recap, etc.), but I was willing and capable to do that work myself. I will also add JBL L36 Decades to the list of potential targets. Unless they have been recently rebuilt and refinished, these almost always sell for less than $300, but they almost always need a little work, too (usually at least a refoam of the woofers).
Hey
@Boognish88, please come back and help us help you. Please let us know where you are located and what amp/receiver you will be using to drive these speakers. Let us know if you have basic repair skills and are willing to accept something that is less than perfect cosmetically. If we know your location, we can help you check to see what's available on your local craigslist and maybe a fellow AKer will have something perfect for your needs at a favorable price.
