My favorite speakers of the last few months are Polk Audio stuff. I have two different pair, and I like them. With hifi stuff, liking stuff is about as general and useful info of anything out there. These days used speakers are a good deal, as so many have foam rot that I think the average person is sick of them and buy junky new stuff. I stay away from Infinity stuff as they all rot, and I won't deal with that.
I prefer used, of course, but older 50-early 70s stuff. But nothing I would say try at all costs. Find an idea of your size, watt range and a decent brand - Altec, JBL, Wharfedale, ADC, Kenwood, Ohm, etc. Look on your CL, and check them out.
