Anyone know anything about these subs? Someone I know suggested these over the IDQV312's. Looking for a good sound quality sub. Going to put 2 in a sealed box in the trunk of a small 4 dr sedan. Was pretty set on the IDQ's but then these were brought to my attention.

Parts-Express.com:

I dont know but great link, thinking about a pair of these to hold me over, going for a good price.

Good, well designed drivers. Generally good distortion performance. Based on the TC2+ motor, which was a fairly popular affordable motor design used by many manufacturers in OEM designs back was TC Sounds was thriving. Slight displacement advantage in favor of the Epic. Qts & Fs are pretty similar between the two, so response probably won't vary greatly between the two in similar alignments.

I've not seen any measurement data on the IDQv3, but I would be surprised if they performed $100 better than the Epic (price based on woofersetc.com).

Personally I'd probably go with the TC driver.

X2 on going with the TC Sounds/Audiopulse driver.

I had a TC-1000 at one point. Tha twas built on the TC2 motor also. For the price it was a very good speaker, no doubt. Top notch quality.

I had a problem with mine but that was my own user error :/ so if you want bang for your buck, that's a good bet.
