EP125 Subwoofer

The EP125 is Axiom's answer to a small sub with big sound! The EP125 sub features a self-contained 200-watt amplifier with a robust linear power supply. This power supply gives your EP125 lots of dynamic headroom for burst of heavy bass like an explosion in a movie. Utilizing exclusive Vortex porting and a pure cast-aluminum basket 8-inch woofer, this system produces smooth deep bass output in small living rooms, dens and bedrooms.

* Required Fields

This is an ideal subwoofer to extend bass response with any of our bookshelf speakers - great for music or home theater. Adding a subwoofer allows you to feel the driving impact of deep bass - the bottommost notes of a grand piano, bass drums, timpani . . . you'll love how full your music sounds with the addition of the EP125.

"The EP125 didn't honk or squawk or hang too long on a single note like a lot of other inexpensive subwoofers. What it contributed to the sound -- a firm footing for most music -- was quite welcome." -- Kevin Hunt, Goodsound.com
Sub Driver
Vortex Port

Axiom's seamless cabinetry makes this a handsome subwoofer whose small stature disappears into most rooms. The unusual ribbed Vortex port allows air to escape the subwoofer silently, increasing the bass output you can get from this remarkably small cabinet. The dual-port configuration is a very efficient design.

The EP125 comes with anti-resonance rubber feet or you can choose optional custom metal spikes at no extra charge by clicking on Customize Yours. These feet ensure that the speaker stays put while the rest of the room vibrates around it! Perfect for small to medium rooms.

"'Imagine my surprise when the EP125 kept making some noise all the way down to 25Hz!'"

Professional Ratings & Reviews
"The EP125 is a relatively small subwoofer but it produced respectably low bass notes. Numerous helicopter scenes in this movie effectively placed me close to the action . . . I not only heard but felt the low registers in these sequences."
- Suave Kajko, CanadaHiFi
"I was impressed with both subs and particularly impressed with the EP125. I honestly expected it to struggle, rattle, chuff, and bottom out at the listening levels I was using. It is a testament to Axiom Audio's commitment to quality that their least expensive offering is clearly well designed."
- Tom Andry, Audioholics
"The M2 and EP125 make a superb combination in a small room system... the M2 is a legend in the making."
- Kevin Hunt, GoodSound.com
"The EP125 sub impressed us with its seemingly effortless ability to produce clean, clear, accurate bass that doesn't muddy or blanket the rest of the spectrum while performing at relatively high volumes. . . we easily give this product our recommended award."

Thrilled with the service and ecstatic with the product.

I bought this mighty little sub to augment the two channel sound in my living/dining room. It is now partnered with my NAD 30 watt amp and small omnisat speakers. What a perfect match! The sound is smooth, tight and breathtaking, even at lower dining levels. Well done, Axiom, and many thanks!

Axiom will happily sell you an ultra high power sub (or a pair even...) that will pop the fillings from your teeth (see EP600). If your budget is tight or if you,re like me and you're looking for a sub that will round out your sound (in a small space) you'll find that the 'baby' of the lot is up to the task. Yes you'll pay less for a 'kit' enclosure in a big box store, but don't bother. Several years ago I purchased a 'small' sub from a well-known (formerly Canadian-owned company whose name begins with 'P') speaker manufacturer. It had to be 'special ordered' and it turned out to be a disappointment. Why bother? The mark of a company that has a clear focus on the value of its technology and (more importantly) on the value of its customers, is it attention to detail and value at all levels of its product line.

The EP125 subwoofer adds that necessary bass punch to all my audio enjoyment, whether listening to some classic albums in my CD collection, or simply enjoying the excellent digital sound tracks in the latest movies on my HD tv system with my Axiom surround sound system wired into the home theatre circuitry. For the money invested, the pleasure is priceless!!!
- Brian D.
Thanks. It's great. The sound of my bookshelf speakers is really enhanced. Thanks for the good service, too.

I'm a custom installer. I was really impressed by the sound quality of the EP125. When we were listening to music, it really warmed up the sound without making it muddy. I let the customer hear his in-wall speakers with and without the sub, and he was happy that he invested in the EP125. During the installation of his screen and projector, he commented at least 5 times about how clear, incredible, amazing, etc. that the music was. I will definitely recommend Axiom to anybody looking for a sub.
