10" Downward firing slot loaded woofer

Uses Audio Pro Proprietary ACE BASS amp technology. Its not a servo, or bass equalization design. It stabalizes the impedance the amp sees from the woofer, allowing it to have iron fisted control over the woofer excursion

Unique semi cylinderical tapered cabinet. Sides are soemwhat rounded in order to break up internal standing waves that are founded in conventional cubed subwoofer enclosures.

500 watt amplifier with line level and speaker inputs. 180 degree phase switch. Auto on/off. Variable high/low pass electronic x over.50 to 150 hz.

This subwoofer is approxinately 1 year old, and in excellent condition. Finsih is black ash one tiny nick on the veneer on the back of the woofer. You cant see it, but it can be felt with your hand. Otherwise a perfect speaker. This subwoofer will blend with alot of speakers. Its fast , extends down to 30hz, and is very easy to place in a room due to its slot loading design. If you want a high end subwoofer for a reasonable price then don't let this one pass you by. Prefer local pick up due to the fact that I do not have original box. If necessary I can have it crated, and buyer arranges shipping. I am not on the net alot so if you have questions you can call me at 509-528-0910. Paypal users add 3%
