I was hoping you guys could help me locate a decemt 15" woofer for a subwoofer project. The kicker is that I don't want to have to buy a 1,000 watt amp to power it. Can you get good performance from a Tempest or a PE DVC 15" with a 250 watt plate amp? I currently have a PE DVC 12" in a 3.1 ft^3 box with an Adire PR 15X weighted to 600 grams. It sounds good, but I just have to have more. BTW, the DVC 12" is just powered by a 150 watt plate amp and it pounds.
