Adding damping material tweak to my 15" woofers... when removing one of the woofers from the enclosure I dropped it resulting in the magnet moving and locking the voice coil... Slick move trying to get that final 0.001% improvement that killed a woofer that is no longer manufactured. So after 6 months trying 3 pairs of woofers w/ similar thiel parameters I finally landed on a solution with a minor crossover change. Note there is no damping material on the new woofers and I'm perfectly fine with that. Ugg.
What has been your costliest mistake in this hobby?
For example :I recently learned a hard lesson- I accidentally ran voltage thru my $3000 MC cartridge (kiseki purple heart). I have a TT with 5 prong connector and a phono cable with a 5 prong connector. I accidentally swapped where they plugged into and ran electric thru the tonearm into the cartridge. It was a stupid - not thinking- hasty mistake. When I corrected the problem the cartridge was fried. An avalanche of four letter words followed!
So what has been your biggest and/or costliest mistake?
