Winner of the SoundStage Reviewer's Choice Award!

The Epicenter EP800 is Axiom’s definitive DSP subwoofer and may set a new world standard for ultra-smooth, deep bass extension at astonishing output levels, probing the depths of infrasonic response to a remarkable 13 Hz (anechoic), even to 12 Hz in a room!

"The EP800 proved to be the deepest-playing, most powerful subwoofer I've ever heard. . . I experienced wall-shaking bass that rattled my light fixtures."
-- Vince Hanada, SoundStage!

 Like its stunningly reviewed brothers, the EP500 and EP600, the new EP800 uses XLF (an Intelligent DSP chip) but applies that digital control to a new sealed enclosure with two huge dual-voice-coil 12-inch aluminum drivers, a larger amplifier (800 watts) and a new custom digital code written by its chief designer, Axiom founder Ian Colquhoun. The result further extends bass response and increases output to heretofore never achieved levels in subwoofer performance.

The Deepest. This subwoofer goes down to 13 Hz (anechoic response), creating sound so deep you may not “hear” it in the conventional sense but you’ll sure as heck feel it! It’s like the ominous rumble and shaking that precedes a real earthquake. But rest assured, your house will remain intact. Only your senses will reverberate (and perhaps the crystal in the china cabinet!). The EP800 is the first subwoofer to ever achieve bass extension to 13 Hz anechoically, in a room with no boundaries.

The Smoothest. The Intelligent DSP wants things to go smoothly all the time - no bumps in the road. Using a digital roadmap, the special algorithm controls every frequency from 13 Hz to 150 Hz, never deviating more than 1 dB through this entire range. With the EP800 you won't get one-note thumpy disco bass - you'll get clean, awesomely powerful bass that mines the furthest reaches of human hearing and brings staggering realism to DVD and Blu-ray movie soundtracks as well as music of every genre. Bass drum and pipe organ will be reproduced as if you’re in the concert hall or cathedral, and contemporary rock will have the driving bass power you experience at the best of live concerts.

Subwoofer Ampl Plate - click to enlargeThe Cleanest Loudest Bass. The EP800 plays louder than a live performance at Carnegie Hall or at a rock concert-- an amazing 125 dB Sound Pressure Level! Don't worry about distortion - the Intelligent DSP won't allow it. Instead, it tightly controls the signals to the 800-watt power amplifier and two massive 12-inch aluminum drivers  with dual 3-inch voice coils to provide you with peak performance, never going over the edge into distortion. Crank it up - XLF makes the EP800 unbreakable!

"If you want the ultimate in pure, subterranean bass, the Epicenter EP800 Intelligent DSP Subwoofer delivers."
--, upon awarding it Subwoofer of the Year  

Winner of the Audioholics Best of 2009 Consumer Excellence Award!

To get a truly audiophile ultra-deep bass experience you need a powerful amplifier (800 watts), two massive woofers and a big sealed enclosure - and the EP800 is three for three. Available in upright configuration or a convenient horizontal configuration that is perfect for under screens or behind couches. If you want the ultimate in pure, subterranean bass, the Epicenter EP800 Intelligent DSP Subwoofer delivers.

You don't have to take our word for it - audition this sub in your own home. The EP800 comes with a 30-day in-home trial, an industry-leading five-year warranty and free shipping.

Industry Reviews

"The EP800 v3 subwoofer took the Epic 80-800 system over the top. This subwoofer was so good, it left me begging for more."
-- Vince Hanada,


"This is no mere subwoofer – it's The Hand of Zeus. From the opening credits I knew the EP800 was going to be different than any sub I'd heard previously. . . This is easily the lowest-playing sub I've ever experienced."
-- Chris Eberle, Secrets of Home Theater and High Fidelity
"The EP800 delivers a staggering 125 dB sound pressure level, meaning that it can generate more sound than a live rock concert. If you are an audiophile looking for the best, cleanest sound, then the Axiom EP800 v3 subwoofer is the new high water mark to strive for."
-- Digital Trends


"the EP800 v3 came closer to that reality than I'd heard in my room. Watching this scene, I could feel the air moving across my legs . . . The EP800 proved to be the deepest-playing, most powerful subwoofer I've ever heard."
-- Vince Hanada, SoundStage!


"I am now convinced that the EP stands for “Earth Pulsator”. The bass that the EP800 puts out is deep, rich, solid, very tight, impactful and unblemished. I was easily able to go from two subs to the single EP800 once I found the sweet spot and haven’t looked back."
-- Dale Rasco,

Customer Comments

Customer Comments

Below are a few of the many reviews that our customers have been kind enough to send us.

I received my order of M80s, VP150, QS8s and EP800 sub a week ago. I would like to put everyone's mind to rest regarding the EP800 as a comparison to other Axiom subs. It is a literal beast!!! It has the deepest, smoothest, clearest and clean sounding bass I have ever heard. And I have heard plenty. The sound is unbelievable. In my opinion, the EP800 is ahead of its time.


If your budget can handle the extra cost or if you can delay your purchase and save the extra cash to get the EP800, you will thank yourself a million times over. This sub will add sound to your audio system that will leave you, your family and friends with their mouths wide open.
