Not sure what the motor is, its similar to what comes on a lightning audio storm subwoofer. Im assuming a tc9? but i am unsure what exactly it is. ID converted is 2.931 inches and OD converted is 3.448 inches.
Looking to purchase 2 Epic 8s or 2 TC 1000 8 inch subwoofer. Also looking for 2 15 inch cones with 3 inch coil opening, 2 10 inch spiders, and 2 3 inch voice coils.
