Axiom Audio EP500 Subwoofer Review


On my reference subs the bass was authorative and well-tempered, but with the EP500 thrown in the mix, slam and "felt" response was elevated to a new level. There were times I felt as if someone had installed tactile transducers under my couch and I...

Incredible depth and slam ; Oodles of output ; Very musical ; Balanced Inputs

Boxy looking appearance ; Single Line Level Input ; Not magnetically shielded

Product Specifications

The biggest advance in subwoofer technology in the last 15 years is here! The Epicenter EP500 is the first subwoofer of its size to truly go down to a couch-shaking 19 Hz in an anechoic environment. How is this possible? The XLF (a DSP chip) enables the EP500 to deliver spectacular deep bass - as low as 18 Hz in a room! Though claims of 19 Hz are made every day by manufacturers, specifications are normally calculated in unrealistic environments (like a closet!). Planning on using your sub in a real room? The EP500 achieves ultra-low bass with none of the uneven performance of conventional subs - Intelligent DSP doesn't allow peaks and dips. It controls every frequency from 16 - 100 Hz, maintaining a smooth, flat response within 1.5 dB across the range. That means you'll hear undistorted, profoundly deep rumbles all the way to 18 Hz. What's more, this subwoofer is unbreakable. The EP500's massive 12-inch aluminum driver with a 3-inch diameter dual voice coil, and its companion 500-watt power amplifier are tightly controlled by the DSP. Its special algorithm commands the subwoofer to deliver peak performance without ever being overdriven. And 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!
