RE: Thiel's need crossover surgery - info needed
Posted by neolith on December 27, 2016 at 08:54:36:
I found pictures of the XO on www.diyaudio.com. It uses non-polar electrolytics. Replacement looks straight forward if you can handle a sorldering iron. I would expect a bad electrolytic to show leakage so visual inspection may confirm your diagnoysis. A bad cap presents as a short and in a first order high pass filter it would allow the mid-driver to range into low frequencies where it was not designed to go. The best way to evaluate the crossover would be with a cheap LCR meter (under $50 on eBay) which would be much cheaper than a repair shop.
