Want realistic home theater bass impact? The EP175 uses a powerful 175-watt internal amplifier to produce convincing low frequency effects - explosions and deep musical bass from home theater sountracks. This isn't a low-budget one-note squawking box - you'll be impressed with the tuneful response of this sub.

"The EP175 could be adjusted to rattle the walls at the appropriate times and simply blend in with the towers when not being called upon to perform their low frequency antics." -- Mike Bell, Designtechnia

The EP175 features a robust 10-inch aluminum-cone driver and cast-aluminum basket, which provides more linear performance than paper cone woofers; it is less susceptible to the distortion and breakup that plague other subwoofer cone materials. Our proprietary Vortex port is a highly efficient dual-port array that eliminates port noise yet increases low bass output.

Even more features set this sub apart from competitors in this price class. The EP175 boasts both semi-pro balanced as well as unbalanced inputs and outputs, so its compatible with any home theater receiver - conventional or professional.

This is an ideal sub for typically sized living rooms (approximately 20 x 12 x 8 feet). The EP175 comes with anti-resonance rubber feet or you can purchase optional custom metal spikes to keep the sub secure. 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.

Audition the EP175 in your home for 30 days. Features an industry- leading five-year warranty and free shipping!

Industry Reviews

"The sub cranks out nice, deep and rich bass that'll rattle your walls if you want it to. Surprisingly for this price point, the sub comes with balanced and unbalanced inputs, which makes it compatible with broad range of receivers or amplifiers.
-- Jim Bray, Technofile


"IThe EP175 is fast and tuneful and very, very clean. If you take the time to set it up optimally with the M22s, the results are astonishingly transparent and musical. That $900 speaker system will give you bass down 30Hz and a seamless, thrillingly musical soundstage. If your HT system has to perform double duty and play your music as well as your films, you could do a lot worse than the EP175. In fact, you'd have to spend a lot more money to do better."
-- Wes Phillips,



". . . bombastic orchestral scores, pounding LFE tracks, densely layered sound effects and ambiance. The Axioms handled it all with panache, serving up a vibrant sonic performance, with all the dynamics, impact, detail, and spatial definition that you could ask for."
-- Kevin Elliot,

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

It shook my drink off the table. Excellent!
-- Bob B., AZ USA


Excellent integration with main speakers, tight controlled bass and excellent build quality.
-- Kenneth V., PA USA


I bought this for music only, due to clean no distortion sound. Fantastic quality and value. The customer service I received from Axiom was second to none. Two BIG thumbs up for this Canadian company.
-- Tony B., ON CA


I spent a few months without a sub and am now wondering why I ever waited so long before buying the EP175. Initially, I was considering going with another company for the sub. I narrowed it down to three competitors. At first I wanted a downward or floor-firing sub; though it was the EP175’s musical proficiency that sealed the deal. All the floor-firing subs had a lag, or delay if you prefer, on all music. Nothing will hurt a musician’s or music enthusiast’s ear more that hearing a bass riff or for that matter a drummer’s double-base run sound sloppy and uneven. It should also be mentioned that the EP175 does a fantastic job in any movie as well. Deep tight bass = EP175. 
-- Carl-John, QC CA

I set up the M22ti's and the EP175 in my billiard room last night. These speakers replaced some ancient EPI speakers I bought about 25 years ago.
The sound is incredibly improved. I had to hook up the subwoofer on the high level inputs since my amp is an early model A/V amp with with no sub-woofer output. First played some of Dave Grusin's "Cinemagic" CD (some deeply orchestrated movie themes), and played with the placement, crossover, levels, etc.

My son and I then settled in to watch several DVD concerts, simply in awe of the sound. My wife was stopped in her tracks at the impact (Peter Gabriel at the time), and sat down with us for the rest of the concert.

Clearly, I am very pleased with the purchase. Even the analog cable TV (also on this system) sounds great.Thanks,
-- Rich T., AZ USA
