Audioque HDC18 Carnage

[Justinh722 10+ year member]

My buddy picked up an older model Audioque HDC18d2. I built him a box around 6.2 cubes tuned to 35 hz because he planned to run it in a mini van. Gave this monster some juice and it played decent at low volume. Sounded ok with sub up port back. Decided to turn the volume up a bit more and the sub just stopped. It literally just froze up.

We could hear the rattling from the voice coil and I instantly thought we blew it. Tried to move the cone and it was rock solid. Got it home and ripped it apart to find this. The pole piece had shifted to the side and the triple stacked magnets had also shifted. The coil is still in great shape. Ohmed out to 2 ohms. The motor is a big paper weight now. I noticed a chip in one of the magnets. Clearly it had seen some trauma at one time. Guy sold him a bunk sub.

Currently rebuilding the sub with an FI BL motor.

I would be getting in touch with the seller.

He said he lost the guys number. Granted he only picked the sub up for 140 bucks, but still. It was a Craigslist transaction. At least I get to try my hand at building a Frankenstein sub.
