I've seen pics where it was a triple stack and the aluminum coned upward, and then I've seen pictures where they come upwards with a curve like a Hershey kiss. I have the one that just cones up without the curve, not sure if it's the concept or original.Iirc it's a 4 layer 4" coilIs this a destroyer or concept csp (same motor)
You can get the csp motors for around $100 to $150 shipped on eBay
I contacted psi yesterday figured I'd have to wait til Monday for a response. I'll pm Joseph though thanks for the linkThere are a few options. But I would get ahold of either PSI or Joseph Smith @GCA (https://m.facebook.com/GenesisCustomAudio/) I have a 12" he built from one and it's a beast! He's on here but I can't remember his screen name.
