WOW! Deep, deep bass response, incredible power, precise reproduction. The EP350 shakes your senses. This powered sub has a 12-inch cast basket aluminum driver, bass reflex porting, and home theater realism unlike any you've encountered before. Dinosaur footfalls? Explosions? You'll be amazed at the rumbles.

This is an entirely redesigned version of the EP350 subwoofer, using the same driver and enclosure of its award-winning big brother, the EP500. It now features a huge rectangular port for extraordinary bass reinforcement, and a massive 300-watt amplifier for home theater bass you can feel.

"the room shook and it seemed like the EP350 would never bottom out – it sounded great." --Ian Bell,

The EP350 provides serious bass extension for musical use, too - even the lowest kettle-drum notes are reproduced as tightly as in a live concert.

This sub perfectly suits larger rooms, from 2,500 to 6,000 cubic feet. We've included anti-resonance rubber feet or you can purchase optional custom metal spikes with this monster sub -- something has to help you keep it down! It features an output jack so that you can 'daisy-chain' a second subwoofer into your system for even smoother bass response throughout the room.

You don't have to take our word for it - audition this sub in your own home. The EP350 comes with a 30-day in-home trial, an industry-leading five-year warranty and free shipping.

Professional Reviews

Industry Reviews

"The EP350 subwoofer really punched out the bass. If you're shopping for home-theater speakers, the Epic 60 should definitely be on your must-audition list."
-- Vince Hanada, HomeTheaterSound; Reviewer's Choice Award, 2003


"The low frequency producing EP350 powered subwoofer produces a clean tight bass. This effect added a clean bass punch while never revealing its placement . . . I haven't heard anything else in its price range that comes close to this level of performance."
-- Brian Mitchell ,

"...we would not change a thing; they are that great . Because Axiom offers the Epic 80 home theater system at such a value, anyone can have audiophile quality speakers that rival more expensive brands."
-- Ian Bell,


"I never felt as though I would have to run for the volume control due to unwanted distortions. The EP350 subwoofer created a clean, controlled bass response that filled the room during bass demanding scenes."
-- Shamus Coghlan, Toronto HiFi

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

Well, the EP350 arrived today and it is absolutely incredible. I have no idea what the EP500 would have done - this thing fills the room with wonderful, commanding bass. Starting out with Alan Parson's "Games People Play" when the drums kick in is fantastic. Then, my wife is a Lord of the Rings fan so we watched the 2nd one and could actually FEEL the flapping wings on the whatever-was-flying-around thingies. Amazing.
-- Brian S., SC


If you want lots of deep BASS, the EP-350 is the product. I have the amplifier turned down and I still have to look at using two hangers for all my pictures in order to keep them straight. The EP-350 will rock your world. Literally!
-- D. H., NS


Now we’re talking BASS!
-- M. K., ON


This is a great sub.Sounds great and seems to be built just as well. Works great with my M60TI. Very powerful with no distortion.
-- Scott C., ON

Well I've managed to get everything connected last weekend. All I can say is that the quality of what I now hear, is only surpassed by the *ear to ear* smile on my face at each listening experience. Not to mention the visually appealing fit the loudspeakers now display in my newly renovated salon. BTW I've succesfully managed to locate my sub, where the bass response of the EP350 in my near 4000 cu. feet vaulted salon, is outstanding. No need for two of these puppies. And I've just listened to stereophonic CD and radio aired material so far. Needless to say I am a happy camper.

Again thank you. It's been a pleasant experience dealing with Axiom and am confident I will enjoy my recent aquisition for many years to come.

From a proud Canadian Axiom customer and satisfied music enthusiast.
-- Francois A., QC
