EP600 Subwoofer

EP600 Subwoofer

Deep, smooth, clean, loud bass that will bring performances to life. For detached homes only!

Featuring XLF (Extended Low Frequency) Intelligent DSP Technology

The Epicenter EP600 is going to transform your listening experience. With the help of XLF (an Intelligent DSP chip), you will finally hear spectacular deep bass -- as low as 15 Hz in a room! The EP600 XLF produces the deepest, smoothest, cleanest loud bass you will ever hear:

The Deepest. This subwoofer goes down to 16 Hz (anechoic response), creating sound so real you not only hear it - you actually feel it. Sure, claims of 16 Hz are made every day by manufacturers, but you'll only hear it if the sub is in a tiny closet-like room like the one they're measuring in. The EP600 is the first subwoofer to ever achieve it anechoically, in a room with no boundaries. You'll actually hear it all - guaranteed - and in most rooms, you'll even experience 15 Hz!

Powered Amplifier

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 16 Hz to 100 Hz, never deviating more than 1.5 dB through this entire range. With the EP600 you won't get 'bass boom' - you'll get clean, powerful bass that mines the depths of human hearing.

The Cleanest Loudest Bass. The EP600 plays louder than a live performance at Carnegie Hall - an amazing 122 dB! Don't worry about distortion - the Intelligent DSP won't allow it. Instead, it tightly controls the signals to the 600-watt power amplifier and massive 12-inch aluminum driver and its dual 3-inch voice coil to provide you with peak performance, never going over the edge into distortion. Crank it up - XLF makes the EP600 unbreakable!

"The Axiom Epic 80-600 system was absolutely unbelievable - like having the power of Mother Nature right at my fingertips." -- Ray Adkins, Audioholics

To get a truly audiophile ultra-deep bass experience you need a powerful amplifier, a tight woofer and a big enclosure - and the EP600 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 EP600 Intelligent DSP Subwoofer delivers.

"The EP600 v2 had no trouble filling my room with tons of extremely loud, extremely deep, and, most important, extremely tight bass. In fact, it provided incredible performance in every way imaginable, and deserves to be included on the short list of affordable, reference-quality subwoofers. . . Reference-quality bass."-- Roger Kanno, HomeTheaterSound.com

You don't have to take our word for it - audition this sub in your own home. The EP600 comes with a 30-day in-home trial, an industry-leading five-year warranty and free shipping.

"'The sound was ultra deep, extremely loud, and exceptionally clean.'"
Doug Schneider, SoundStage.com
Professional Ratings & Reviews
"'The EP600 is very musical, can play lower than we can hear, and when called upon can wreck the house with gut-wrenching high SPL. . . it is a true audiophile subwoofer with impressive slam.'

'The EP-600s belted out huge amounts of tight lightning- fast undistorted LFE.'"
- Ray Adkins, Audioholics
"Loud yet distortion free, powerful but never brutish, it never bottomed out... the EP600 is by far the best subwoofer we have yet tested."
- Octavio Umana, Canada HiFi
"The Axiom speakers I reviewed were absolutely unbelievable.These speakers are without a doubt among the finest speakers built in Canada. They set a new benchmark for performance at this price and about the only thing left to say is 'WOW!"
- Ray Adkins, Audioholics.com (on the Epic 80-600)
"The Axiom EP600 subwoofer is a rare example of the subwoofer breed. It's big but it's quick. It goes really deep but maintains its musical integrity at higher frequency than most people will need it to go, meaning that it's equally at home in both music and home theater systems. When taken in its entirety -- features, performance and price --, I don't know if it even has any competition."
- John Potis, 6 Moons
"The impact and foundation of the EP600's low frequency grip you with their realism. Doublebass was a delight - neither smearing nor timbre splitting. It was as though my speakers were on steroids!"
- Robert Lussier, Quebec Audio Video
"The EP600 v2 had no trouble filling my room with tons of extremely loud, extremely deep, and, most important, extremely tight bass. In fact, it provided incredible performance in every way imaginable, and deserves to be included on the short list of affordable, reference-quality subwoofers. . . Reference-quality bass."

'Years ago when i searched for Subs I found the EP 500. When I changed systems to bookshelf Sonus Fabers I knew i need more 'breath' to make up for the smaller main speakers. I love Axiom Subwoofers so the brand wasn't even up for debate. Only the model. With Brent's help I chose the EP 600 over the EP 800. I can't explain it logically but best to compare the choice to saying I like the way a good record plays on a god turntable over any '64 bit' CD. The 'breath' is amazing.'
- Dave C., FL
The EP-600 is everything I wanted in a subwoofer. It fills my 7000 cu ft space with clean quality bass. I love this sub for both HT and music. I have had several subs in the last couple of years including the Velodyne DD-18 (my previous favorite). The EP-600 is now the sub all others will be measured against. Thanks to all at Axiom!
- Robert K., CA
The EP-600 absolutely blows me away! i'm still in awe as it lays in my living room. I'm very pleased with you guys. im getting M-80s for xmas :-)
- Daniel V., NC
Hi guys, yes I received the EP600, what a piece of machinery!! I can't believe how well the M80's, QS8's and the VP150 blend together with this sub. It is a sound that I have been searching for, for some time now.
- Marty P., ON
Thank You for your fast shipping. The hardest thing about our transaction was the wait and you made it easier than expected. I've been using high end equipment for 30 years and your 600 Sub is the best I've heard! The biggest disappointment I have is that some movie soundtracks and CD's don't have the bottom end needed to allow this Sub to show it's stuff! Your Sub has put me on Top, in my circle of Home Theater Buffs.
- Gary G., CA
Thank you very much Brent! The EP600 is simply amazing and as usual you folks are clearly head and shoulders above any I've ever ran across.
- Richard F., FL
