EP500 Subwoofer

EP500 Subwoofer

Expect thundering rock, explosive movie special effects, or the deepest musical foundations of classical and pop music to be revealed with the Epicenter EP500.

Featuring XLF (Extended Low Frequency) Intelligent DSP Technology

The EP500 uses intelligent DSP to make everything perfect. The EP500 has a perfectly linear response down to 18Hz. This gives you bass realism like you have never experienced before. The intelligent DSP also means your EP500 plays really loud without ever having to worry about unwanted pops and noises coming from your subwoofer. 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. 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

Sub Driver
Ultra-Low Bass

The amplifier in the EP500 is in a completely different class than other subwoofers selling for under $4,000. It has a large toroidal transformer and 66,000 uf of capacitance storage. This amplifier will deliver big bass peaks effortlessly. The EP500's massive 12-inch aluminum driver with a 3-inch diameter voice coil is capable of handling the high-power peaks from the amplifier easily. And the special algorithm commands from the DSP will deliver peak performance without ever being overdriven. 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

You don't have to take our word for it – audition this sub in your own home. The EP500 comes with a 30-day in-home trial, an industry-leading five-year warranty on all components and free shipping.

I use dual 500v4 finished in walnut natural satin along with an 800v4 for my 4200 cu.ft. A/V room. The dual 500s add three-dimensionality to the already great bass from the 800. The 500s have convincing infrasonics during movies and drum bass and resolve every bass guitar note in a growling and very articulate manner. I now need two more to complement the great-sounding M2OW in my living room. The 500 sounds very similar to the 800 that I reviewed at the following link.

I purchased this speaker in real wood, rosewood and it''s as beautiful as is it gracious in sound quality. My wife calls it my second wife as I have been glued to it since it was delivered. The depth sound that it produces is simply breath taking, Rich, deep, enveloping but not overwhelming. It''s an amazing piece of art.

I've ordered the M22s and the EP500 as I build my home theatre system. Customer service has been incredible, extremely helpful and responsive. The packaging is first rate. The quality of the speakers is remarkable - the M22s have a great soundstage, open, crisp and airy. The EP500 adds a rounded depth and dimension without boominess. Keep focusing on quality products, great customer service, and competitive pricing. I'm very happy with my purchases. I look forward to rounding out my system with Axiom speakers.

Unfortunately I am not talented enough to enunciate all of the superlatives which these subwoofers so richly deserve. I can say that they have given me a new definition for what it means to bring an entire system thunderously together. I knew that audio material was available which I previously was not hearing and feeling but, it can surely be heard and felt now . . . and very convincingly so. Thank you Axiom Audio for helping my family
- Mike, FL
I found you through the different review sites such as Audioholics, Home theater Magazine, Stereophile, sound and vision and Canada Hi-Fi. I build up a list of potential manufacturer from there and then took a decision to go with Axiom for my home theater renewal, piece by piece! Starting up with EP500.Price/performance ratio.
I really like the fact you distribute your products yourself only, my $ gets further that way I would think.
It's Canadian! With brands like Axiom, Paradigm, Totem, Class

Just returned from a business trip to find the EP500 waiting for me. I was rather amazed that the *GIANT* 80-pound box made it half way across the country without a scratch on it... but the unit was securely packaged and is working just fine. In fact, it works so well that my wife and I both stood mouths open (not kidding!) as it shook the rafters and window glass in our house. Amazing! Love that palpable, tight bass. More testimony to follow after I've had a chance to get the sub completely dialed in....
