Axiom Audio EP-500 v2 Subwoofer, like new

Featuring XLF (Extended Low Frequency) Intelligent DSP Technology

The biggest advance in subwoofer technology in the last 15 years is here! The Epicenter EP500 is the first subwoofer of its size to truly go down to a couch-shaking 19 Hz in an anechoic environment. If you've been longing for the kind of seat-rumbling experience you get in a good movie theater, you'll get it with the EP500. How is this possible? The XLF (a DSP chip) enables the EP500 to deliver spectacular deep bass -- as low as 18 Hz in a room! Bring on War of the Worlds!

"In every configuration that I tried this sub in, it performed at world-class levels. It is both able to convey subtle musical notes, and earth-shaking low-frequency movie effects effortlessly. It's not a hard stretch to say that this sub's performance matches or exceeds the best 12" subs that are available at ANY price."-- Geoff Cintron, AudioReview.com

Though claims of 19 Hz are made every day by manufacturers, specifications are normally calculated in unrealistic environments (like a closet!). Planning on using your sub in a real room? The EP500 achieves ultra-low bass with none of the uneven performance of conventional subs - Intelligent DSP doesn't allow peaks and dips. It controls every frequency from 16 - 100 Hz, maintaining a smooth, flat response within 1.5 dB across the range. That means you'll hear undistorted, profoundly deep rumbles all the way to 18 Hz.

The EP500's massive 12-inch aluminum driver with a 3-inch diameter dual voice coil, and its companion 500-watt power amplifier are tightly controlled by the DSP. Its special algorithm commands the subwoofer to deliver peak performance without ever being overdriven. And its maximum undistorted output of 120 dB is louder than a full orchestra in a concert hall. At last, professional cinema realism is available in your home theater!

"When I cranked the volume up to obscene levels... I couldn’t hear any distortion from the 12" cone no matter how much I increased the volume -- just solid, deep, room-shaking bass. The Axiom EP500 is a bargain among high-end subwoofers." -- Vince Hanada, HomeTheaterSound
