Strange object found inside a Harmon Citation 7.4 sub
I was working a bit on the internal dampening material in two passive subs. I was surprised to find what looks like crossover inside. It had a bit of a strange configuration. Not sure what all of those resistors are for…maybe trying to head something off when the resistance rises in the upper frequencies.
I’ve have very high quality sub amps so I removed this from the cabinets. Possibly the Harmon Cardon amps used to power these were not dedicated sub amps.
it’s a head scratcher.
