Axiom Audio says its new EP400 powered subwoofer is designed for maximum bass output in smaller rooms. The sub itself is relatively small, measuring 13.75" high and 10.5" wide, but it's supposed to be capable of generating an in-room SPL of 116 dB and a low-end response of 23 Hz. The sub was designed primarily for use in small rooms, such as bedrooms, dens, or home offices. (It's probably not appropriate for bathrooms, where you really don't want to see another bottom end.)

The EP400 uses Axiom's intelligent Digital Signal Processing which is custom-designed with a programming algorithm that "dynamically marries a driver with its digital signal over the driver's entire performance spectrum." The end result, says Axiom, is "unprecedented smoothness or 'linearity', even at maximum output levels in the driver's lowest frequencies." The circuitry makes it "virtually impossible to overdrive an EP-series subwoofer into distortion, even at its highest volume." (That sounds like a challenge to me, but I don't think that's what Axiom intended.)

The EP400 includes a 500-watt internal amplifier and a long-throw 8" aluminum driver. The in-room frequency response is 23-150 Hz (+/- 1.5 dB). It's available in Black Oak, Boston Cherry, Light Maple or Mansfield Beech as standard in-stock finishes, or it can be special ordered in custom vinyl or wood finishes. The standard price is $1,100, which includes sales tax and shipping in the U.S.
