In Reply to: RE: Thiel's need crossover surgery - info needed posted by theaudiohiffle on December 26, 2016 at 18:12:55
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.
I married the perfect woman. The downside is everything that goes wrong is my fault.

As long as you are not cranking it the natural roll off of the driver will kick in. So there should be no distortion even if you shorted the cap out. If it's first order and the cap was shorted it would either sound louder or no sound at all.
And again, I've never seen a speaker cap just go???
Good enough replacement caps are much cheaper than that meter.
Many thanks. Yes, I can handle a soldering iron, and I do have some test gear. So it sounds doable.
