What's better than bass you can feel? How about a subwoofer you barely see? The ESW-M6 provides up to 800 watts of room-thumping bass from a cabinet that measures less than a cubic foot. You'll be impressed by the clean, punchy lows the 6" woofer and dual 6" passive radiators add to your favorite music, games, and movies. Plus, the woofer cones use proprietary Ribbed Elliptical Surrounds™ to increase efficiency and fight sound-muddying distortion.

Controls on the back of the cabinet make it a cinch to add as little or as much bass as you like, and to seamlessly blend the sub in with the rest of your system. The high-gloss finish gives this sub a polished look that complements most flat-panel displays.

  • 200-watt RMS amplifier (800 watts peak)

Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Features

Single Active/Dual Passive Design: The Energy ESW-M6 has three 6" black anodized aluminum cones (one woofer and two passive radiators). The woofer is driven by an efficient 200 watt (800 watt dynamic power) amplifier. Together, the woofer and passive radiators deliver pure, powerful, accurate bass for your music, movies, and games.

Surrounds: The front-firing woofer and side-firing passive radiators each have inverted Ribbed Elliptical Surrounds. This design eliminates surround distortion, causing the subwoofer to play lower with greater output and fidelity.

Finish: The furniture-grade enclosure is hand finished to a high-gloss piano black lacquer finish to ensure durability.

Controls

Volume Control: The rotary volume control lets you set the loudness of the subwoofer relative to the rest of the speaker system. After the volume is set, the subwoofer's volume can be controlled along with the other speakers by the master volume control on the receiver or preamplifier.

Low-pass Filter: The ESW-M6 has a built-in 50-200 Hz, continually-variable low-pass filter that allows perfect blending with your other speakers. If desired, you can bypass the low-pass filter so you can use the crossover built into your A/V receiver or surround processor.

Phase Control: The unit's rotary phase control lets you fine tune the subwoofer's phase from 0° to +360°. A mark is provided at 180°.

Power Modes: The subwoofer features three power modes: Off, On, and Auto. The main power switch turns the subwoofer on or off. When switched to On, the position of the power mode switch determines whether the subwoofer's power is on continually or turns on automatically when a signal is detected on the audio input. When no signal is detected, the sub's amp will automatically turn off after a few minutes.

Connections

Inputs: The ESW-M6 features a pair of gold-plated RCA line in/sub in jacks. If you are connecting the subwoofer to a receiver or processor with a LFE or Subwoofer preamp output, you should connect a single RCA cable to the LFE/left input.

Tiny footprint...BIG sound

Written By Josh S, Knoxville TN on Thursday, March 31, 2011

Crutchfield Customer Review (What's this?)

Pros: super small footprint & shocking power for it's size.
Cons: price a bit steep if not on sale, wish some controls were more accessible

I recently purchased the Energy ESW-M6 as an addition to some Polk TSi-100
bookshelf speakers. I wanted a simple, but effective system for a turntable/CD
player and have the Onkyo TX-8555 receiver pushing everything.

I'll have to admit, I had great trepidation about this subwoofer's ability due
to it's size, but this thing is performing as advertised!! It adds all the bass
and depth that the Polk's don't have and the woofer itself is tiny!! My home is
small, so space is a very important issue. I tried turning off the woofer to
see the difference and the Polk's just sounded tinny without the Energy pumping
the bass, so I felt justified in my "blind" purchase.

Seriously, I was shocked by the sound coming out of this little guy. Now, if
you're looking for earth-shattering lows, you're obviously going to be going
with a larger model. If space is an issue and you just need solid, deep-enough
bass to complement some bookshelf speakers go for it! Controls such as on/off
and adjustments are on the back, so nearly impossible to get to depending on
where you put it, but that's true of most woofers.

Crutchfield had one of their great sales on this when I purchased, so I was
fortunate, but even at regular price, the size to power ratio of this woofer is
worth it!!
