A truly specialty subwoofer, designed to meet the needs of connoisseurs of profoundly deep bass extension who are looking for the perfect solution for ultra-low bass in smaller rooms. The well-proportioned EP400 meets the requirements for a compact, inconspicuous subwoofer with cutting edge performance.

Using proprietary Digital Signal Processing (DSP) technology, the EP400 packs a huge 500-watt internal amplifier that provides subsonic bass reproduction - as low as 17Hz - into a small enclosure. The subwoofer features an 8-inch cast aluminum basket long-throw woofer - and it uses the custom DSP algorithm to extract maximum sound pressure levels as high as 116 dB from an enclosure only 13.75 inches high!

"The Axiom EP400 Epicenter Subwoofer is a powerful subwoofer despite its small size. This 8-inch subwoofer delivers power, clarity, tightness, and undistorted deep bass response for both movies and music. . . My impression of the EP400 is extremely positive, making this subwoofer a real winner, especially for those looking for a high-performance subwoofer in a smaller room." -- Robert Silva, About.com Home Theater Guide

The EP400 completes a state-of-the-art system for movies, classical music, rock performances or other forms of entertainment that demand heart-pounding realism and fidelity. Use it to provide the rock-bottom bass reinforcement for a compact sub-sat music system in an office, den or bedroom. For ultra-smooth bass for every seat in the room, 'daisy-chain' a second EP400 into your system using the supplied line-level output.

Subwoofer Ampl Plate - click to enlargeTrying to decide between an EP400 and an EP500? The EP400 was not created to be a less expensive version of the EP500; in fact, if you do not have any concern with the enclosure size, then choose the EP500. What the EP400 enables is that the master bedroom or den can have subwoofer response as powerful as the home theater room, in an enclosure small enough to tuck in a bookshelf or under the bed.

You don't have to take our word for it - audition this sub in your own home. The EP400 comes with a 30-day in-home trial, an industry-leading five-year warranty and free shipping.

 

 

 

 

Professional Reviews

Industry Reviews

"This heavy, little guy may be designed for small spaces like bedrooms and dens, but with 500 watts of amplification tempered by digital signal processing pouring out of an 8-inch long-throw aluminum driver, the EP, standing for "Epicenter", doesn't seem a joke."
-- Marshal M. Rosenthal , E-Gear

-- Robert Silva, About.com Home Theater Guide

"Small is too big a word to describe the EP400. Try tiny. . .With acoustic bass, it had texture and finesse, without the constant drone of one-note bass I often hear from lesser subs."
-- Vince Hanada, HomeTheaterSound.com

Divider

"The EP400 has a driver that is so beefy that I literally could not get it out of the enclosure. The amplifier on the EP400 weighs in at a stunning 16 pounds! That's some serious amplification for such a small sub."
-- Tom Andry, Audioholics
