Product Description

From the Manufacturer

From the Manufacturer One of the most important speakers in any system, the subwoofer never gets the respect it deserves. We invest a lot of design time and effort into building the industry’s best subwoofers, offering unparalleled performance and sonic accuracy. Energy's subwoofer line is certain to have a model designed precisely to fit your needs.

ESW-V8: A Low-Frequency Wonder

The rear-firing port gives the ESW-V8 room-shaking power

Capturing all the sonic excitement of low-frequency performances, the high-style Energy ESW-V8 subwoofer perfectly rounds out a home theater or two-channel stereo music system. In fact, this masterpiece of sound and design works well with our flagship Veritas Series, RC Series and Take Series.

A bass-reflex design with a single rear-firing port, the ESW-V8 shakes things up by employing an 8-inch woven composite fiberglass cone with patented Ribbed Elliptical Surround™. This proprietary design eliminates surround distortion, enabling the subwoofer to play lower with greater output and fidelity. An efficient BASH® amplifier allows this hard-hitter to deliver 200 watts of RMS power and 800 watts of dynamic power for the accurate reproduction of music and movie soundtracks.

The ESW-V8 features line and speaker level inputs and has an 18dB/octave variable low-pass filter that is continuously adjustable from 40Hz to 120Hz. A -180/+180 variable phase control facilitates the ideal acoustical integration of the subwoofer with other speakers in the system. An "auto power" feature enables the subwoofer to turn on and off automatically, based on the presence or absence of an audio signal.

In addition to delivering tight and powerful bass response, the ESW-V8 elegantly blends into any living environment. It features seven layers of polyurethane that have been hand sanded to enhance its lustrous high-gloss black finish.

The Energy Advantage

Energy brand speakers are the culmination of over 30 years of scientific research and development in acoustics, speaker engineering and manufacturing. The philosophy of design behind every Energy brand product has its foundation in our pioneering study with the Canadian National Research Council (NRC) almost 20 years ago, which lead to incredible breakthroughs in speaker technology. Understanding how people listen has led us to three simple, yet vital factors that are the basis for the Energy brand’s speaker design and construction. These factors are flat on-axis frequency response, wide and constant dispersion, and low distortion.

Flat On-Axis Frequency Response with Wide Bandwidth

Flat frequency response is the ability of a speaker to reproduce the entire audio range in a uniform manner. By ensuring that no one frequency dominates over any other, Energy ensures that every sound is reproduced the way it was intended, as naturally as possible.

Wide and Constant Dispersion

This refers to sound—at all frequencies—which radiates from the loudspeaker, ideally in an even pattern, in all directions throughout the listening environment. In nature, sound radiates all around us. A speaker must be able to reproduce this as accurately as possible, thus spreading the sounds we hear constantly, consistently.

Low Distortion & Resonance

While no speaker system is totally devoid of distortion or resonance characteristics—speaker systems with as much as 25-30% Total Harmonic Distortion (THD) at bass frequencies can still be considered "high end"—Energy consistently achieves significantly lower distortion levels in its entire line of speaker products. It's an improvement that is clearly audible.

A Constant Pursuit of Excellence

This basic Energy philosophy hasn't changed in over 30 years, yet our extensive research methodology and the available technology and materials have steadily improved, enabling Energy to continue to manufacture speaker systems that achieve outstanding performance through consistent improvements to all of these three critical parameters.

We’re constantly working on designing new and improved speakers. Our engineers and designers are diligently working to better reproduce sound in the most realistic manner possible. Years of expertise and the best measuring and testing equipment available allow us to continue to push the boundaries of sound reproduction.

5.0 out of 5 stars The little sub that could - all the way down to 31Hz!, April 29, 2009

By	B. Campbell (Richmond, VA USA) - See all my reviews (REAL NAME)

I'm using this sub as part of a 7.1 system that includes two Energy Take TWR speakers for the front channels, a Take FPS for the center channel, and four Take SAT speakers for the surrounds. It produces deep bass down to about 31Hz, which should be plenty for all but the deepest of bass aficionados. This results in a sub that handles all but the most challenging home theater tasks with ease. For example, at the beginning of the movie "Transformers", you hear and feel lots of deep bass for the helicopter in flight, but you just hear (rather than feel) the shock wave that the evil transformer sends out in it's first attack. (In all fairness, you'd need at least a 12-15" sub with considerably more power to feel that in your living room.)

The flip side of this lack of hyper-deep bass response is that the ESW-V8 is an extremely musical sub. I've thrown a large quantity of material at it, anything from classical to pop to dance to live jazz, and it handled them all with equal aplomb.

Overall, I'm very happy with my purchase and would recommend this sub to anyone looking for a solid upgrade to their home theater system.
