Product Description

The Dayton Audio IB series subwoofers are designed to produce extremely low, clean, uncolored bass in infinite baffle situations. Ideally, the subwoofers are situated between the listening room and an attic, basement, or garage using the floor, ceiling, or walls to separate the front and rear sound waves. Benefits of the infinite baffle approach include extreme low-frequency output, very clean and distortion-free sound, lack of large enclosures within the room, and amazingly loud bass with modest power amplifiers. Combining high sensitivity, good mechanical damping, and excellent excursion capabilities, the IB series subwoofers are the only drivers on the market designed specifically for infinite baffle situations. Made in the U.S.A. 5 year Limited Warranty.
