"Combining awesome power and wonderful responsiveness, the DB1 is unlike any subwoofer you may have seen or heard before.In fact, we think it’s the best you’ll hear anywhere.
For a start, the DB1 has not one but two opposing 12-inch long-throw drivers. With more output power than a single 15-inch driver, their balanced drive configuration cancels out structural vibration. Then there’s the fact that the DB1 has its own 1000W digital amplifier, ensuring staggeringly low frequencies from such a compact speaker.
But the DB1 is also designed for the subtle things in life. The control of Digital SignalProcessing keeps the output dynamic and accurate whatever the program. The setup menu lets you optimize the speaker for different applications, such as movies
and music, or different listener preferences.And did we say the best anywhere? It even comes with equalization software that automatically fine-tunes the speaker to match the unique character of your listening room.
Power. Responsiveness. Control. Put them together, and you’ve got a sub that sounds like no other."
