Energy ESW-8 200 Watt Powered Subwoofer – Tested & Working Perfectly

Experience deep, tuneful bass with the Energy ESW-8 powered subwoofer—an ideal combination of technology, performance, and design that affordably brings powerful low-frequency response to both home theater and two-channel music systems. This unit has been thoroughly tested and is working perfectly in every respect.

The ESW-8 features a bass-reflex design with front-firing port, employing an 8″ MMP (Mineral-filled Polypropylene) cone with Energy’s patented Ribbed Elliptical Surround technology. This proprietary design eliminates surround distortion while enabling the subwoofer to play lower with greater output and exceptional fidelity. The efficient internal power amplifier delivers 200 watts of clean, controlled output for accurate, deep, and powerful bass response that complements any speaker system.

Built with attention to detail and performance, the ESW-8 offers comprehensive connectivity including both line and speaker-level inputs, plus a variable low-pass filter for seamless blending with a wide variety of speakers—including Energy’s own C-Series and Take Series models. The automatic power mode switch turns the subwoofer on and off based on signal presence, while the classic Gloss Black finish fits comfortably into any living environment.

Energy is a Canadian speaker brand from Audio Products International (API) of Scarborough, Ontario, the same company and factory behind Mirage. API was founded in 1973, and the Energy brand dates from the late 1970s or early 1980s. We carry Energy bookshelf speakers, towers, centre channels and subwoofers. We've had more than 170 Energy listings so far, covering more than 75 different models. Every used Energy here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.

Our five best-selling Energy models so far: the RC-mini bookshelf speakers, the e:XL-S8 and ESW-8 subwoofers, the e:XL-C centre and the C-300 towers.

The Energy story

Howard Heiber founded Audio Products International in 1973 in Scarborough, Ontario, as a builder of private-label speakers. Energy says its brand dates from 1973; other sources point to the late 1970s or early 1980s, when API took on the Energy and Sound Dynamics names.

Research in Canada. Energy took part in the National Research Council of Canada's listening-test research from 1977 to 1986, and its speakers were built at API's Scarborough factory, which it shared with Mirage.

Veritas and Connoisseur. The Veritas v2.8 flagship was shown at the 1993 Winter CES, and the Connoisseur series followed in the mid-1990s. The Take 5 satellite system arrived in 1997.

New owners. Klipsch Group of Indianapolis bought API, with Energy, Mirage and Athena, in August 2006, and production moved to China around 2006 to 2007. VOXX bought Klipsch in 2011, and Gentex bought VOXX in 2025.

Which Energy is which?

Veritas (1993 onward): the flagship line, such as the three-way v2.8.

Connoisseur (mid-1990s to mid-2000s): models such as the C-2, C-3, C-6 and C-8.

Reference Connoisseur (RC): including the RC-70 towers and the RC-mini, one of our best sellers.

Take 5 and Take Classic (1997 onward): small satellite-and-subwoofer systems.

XL and e:XL (2000s): the entry line. Our best-selling e:XL-S8 subwoofer and e:XL-C centre come from here.

C-series (late 2000s): the vinyl-finished budget line, from the C-50 to the C-500, including the C-300 towers.

Subwoofers: the ESW and S-series, such as the ESW-8 we sell often.

Buying used Energy: what to check

Aluminum-dome tweeters. Owners report broken tweeters on some Connoisseur models. Look closely for dented or cracked domes.

Powered subwoofers. Owners report failed plate amplifiers on some S-series subs. Any sub should play cleanly at volume.

Surrounds. Most Energy woofers of the 1990s and 2000s use rubber surrounds, but some models, such as the RVSS dipole, used foam. Press gently on each woofer surround.

Where it was made. Energy speakers were made in Scarborough into the mid-2000s and in China from about 2006 to 2007. Check the rear label if Canadian manufacture matters to you.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
