Did your E12a have some sort of weavy material for the cone? If so, those were known to have problems back then. Cones were cracking here and there, and voice coils became detached from the cone itself. It's a shame because it was one of my favorite A-series of all time.

The 15's had more problems than the 12's. There was just too much cone area for the stress the voice coil/motor put on it. The 12 that I used had an aluminum backer on the flat cone. That helped strengthen it as well as made a better connection between the "cone" and the voice coil.

The TC-9 motor is extremely powerful. I bought a pair of TC-2000 top assemblies that had be pushed to over excursion and the voice coils had left a circular imprint in the aluminum cone. Luckily my TC-3000's use titanium cones.

welll yea i use to have the one with the wavey material but that thing crapped out on me. But i got the e12a with the aluminum cone now. Those were a limited production sub. i cant imagine going with another sub. its such a superb sub IMHO!

Most TC9 based subs are. Entasi Audio, Stereo Integrity (older Magnum series), Soundsplinter (RL-p series), Elemental Designs (SPV series), Orion (older HCCA series), TC Sounds (TC9, TC-2000 and 10" OEM), Eclipse (not sure what model), Audiopulse (Revo series), etc. Yes, it was and still is a popular design. Hopefully, someone will still use that motor structure now that TC Sounds has gone under.
