Just found a pair of L810's, found one of the speakers has no output from woofers. Midrange and tweeter seem to work. Since it has two, and they both don't work, I figure it isn't the woofer. I had seen a review here that recommended replacing the caps in the crossover, so I may attempt this rather than returning them to the person who sold them to me (for a great price, locally). I have removed one of the woofers and tested it with a MM, a nice 5 ohms, so hopefully it is the crossover. The crossover was fairly easy to remove from the cabinet, behind the lower woofer. There are 4 caps, and they are available for around $50 from Parts Express (4.7, 6.8, 10, 100 mf Solen caps; the 100 is $38!). Questions:

1)would "bad" capacitors be enough to cause this problem (no output from woofers)?

2)there are also two 1.5 ohm 10% 7w resistors (sandstone/cement?). Should I replace these with the Dayton 1.5 ohm 10w 2% resistors?

3) Any other ideas? Get my money back? I have the equipment/ability to do the replacing, and I have a pair of 710's that I love, so I was overjoyed to find the 810's locally.

thanks in advance for the advice
