Have seen a pair on Craigslist.. Went to listen and the guy had the hooked up with cheap speaker wire and to an AV surround receiver watching a live concert... they sounded good. Anybody have any advice what to look/ listen for in evaluating how much to offer. Or are they to old and require too much attention?

Some thoughts:

Some thoughts:

1. Original woofer polyether foam surrounds will have disintegrated into dust a long time ago. If you heard a working pair, you heard woofers with non-original surrounds. It's a roll of the dice as to whether the replacement surrounds perform the same mechano-acoustically as the originals.

2. The Philips midrange surrounds are suspect too. A few decades of passage of time usually does bad, and often unpredictable, things to organic components.

3. Check the condition of the crossover capacitors. Electrolytics "leak" capacitance with time, generally about 1% per year.

The DQ-10 was an inefficient, but great-sounding speaker for its time. Restoring a pair involves many unknowns and may or may not come close to the original. Ironically that may or may not be a bad thing.

For me, I'd buy new.

HTH,
Mark
