I used to have some Polk SDA 2, but had to sell them after I got married. Now that I'm older, I yearn for my polks again. A pair of used Polks will stomp anything comparably priced today. If I pick up a set on ebay or somewhere, can I still get new parts for them if needed.
If I can, how much is a 6.5 driver and a tweeter? I bought a new driver once about 15 years ago for about $50.
