I have 5 of these used Orion H2 12.2 subs left that are good and 2 that are blown. They are dual 2 ohm. Selling the good ones for $175 shipped each, $325 shipped for a pair, $625 shipped for 4. Sell the blown ones for $100 each shipped.
Those are some power hungry monsters. I had two of them a while ago. I never did push more than 1K W to any one of them, but they got extremely loud in my vented box.
