I'm selling 2 MTX Thunder 4500 series subwoofers in a ported box made by MTX specifically FOR these subwoofers. This setup costs ~$230 new @ Circuit City and such, and I've only used these subs for about 2 weeks since I've bought them. Now that I'm getting my car track prepped these have no place in my car, so I'm trying to get rid of them for $130 OBO picked up (will not ship, will meet within a reasonable distance)
Here are the specs for the MTX Thunder Series 4500 Subwoofer:
* 12" Thunder 4500 High-Performance Subwoofer
* ALDS (Asymmetrical Linear Drive System)
* Flat Progressive Spider
* Extended Pole Piece
* High Power Handling
* Rubber Surround
* Strontium Ferrite Magnet
