12" cerwin vego pro subwoofer 800wrsm 1500 peak dual 2 ohm. Only used it 2 weeks as in wasnt loud enough for me and i switched to 2 12s. Been sitting in the box for years thinking ill make use of it and now finally decided to let it go, bought it when it first came out for £850. Grab yourself a bargin on a discontinued subwoofer from a very known brand.
