What a great driver! I run two of these in my theater and could not be more pleased. great product at a great price-point.

Very good subs for the money, probably the best bang for your buck out there if your looking for a driver that will get very low with ease. I have two on a Crown xls 2402. They sound great. I'm also about to put two 1034; ultimax in my work truck. They sound fine sealed and that what they suggest, but they really shine when you have then in a large ported enclosure. Great product. And something odd to add, I was sent 10s when I ordered 12s, I kept them and ordered more 12s... They mount in the same box as the 10s, perfectly. So I'm not sure if there is just a difference in power handling and the size of the motor, but yeah, the 10s and 12s are the same overall diameter, so I'm guessing they have the same cone area?
