Re: Determining Load Ratings When Not Specified (16 ohm)

Too late now, but Dave Rat discovered the series "protection" capacitors he used in the Rat Traps eliminated the amplifier damping from the diaphragms, TAD berillium diaphragms have a low resonance that can be excited by the mid and low frequency driver's SPL, causing the diaphragm to shatter.

After removing the caps he stopped having the alarming (expensive) failures.
