Hello fellow polkaholics. I have come across a set of Polk speakers that the owner has identified as Polk SDA 1. Any advice on what to look out for, opinions on this Model # and what would be the going price for a nice set? Thanks for your input.

    Make sure none of the woofers are frozen, the tweeters work, and none of the rubber surrounds are torn.

    Model 1C. Drivers look correct from what I can see. $300-$400 for a stock pair would be a fair price if the SDA cable is included. Maybe a little more if mint.

    The side panels are coming off, but the drivers and PR's are very clean.

    Thanks for the input F1nut, but can you lell me what PR's are? Sorry for not knowing the lingo. LOL I am a bit concerned about the white over smear around the tweeters. Is that common?

    Passive radiator.

    The tweeters are the nasty SL2000. You'll want to replace them with the RD0194 immediately.

    In layman's terms, the PR is the big round flat one at the bottom. It is "passive" in that it is not driven my electrical energy in a voice coil. Instead the pressure changes in the cabinet from the driven speakers (4 mid-woofers) causes the PR to move (resonate) and produce sound at lower frequencies. For it to work properly, the cabinet needs to be sealed. Otherwise, the pressure escapes and doesn't drive the PR.

    So that is another thing to check. Make sure that the edges and corners are not cracked. You can gently press and hold the PR in and the mid-woofers should move outward and slowly return to their resting position. If they return quickly or don't move at all, then there is a problem; either the cabinet has a leak or the mid-woofers are locked.
