Its real efficent and plays low so it doesnt need alot of power. Overall a great woofer. Sounds great. For the money a great woofer.

For a 12 it liked a big box.

This is a great woofer, I have it running in a 4 cubic foot enclosure, with 2 15" Passive Radiators its tuned to like 18hz. Great woofer, sounds good plays real low. I have also ran it in a small sealed enclosure in car audio. Worked real well.
