Enhance your music or home theater system with deep, powerful bass from the Energy e:XL-S12 subwoofer—tested, working perfectly, and sounding great. Crafted by Energy, a renowned Canadian audio company, the e:XL-S12 is highly regarded for combining punchy output, tight control, and room-filling extension in a compact footprint. This sub delivers serious low-frequency impact for music, movies, and gaming, bringing excitement and realism to any setup.

Featuring a heavy-duty 12″ polypropylene cone driver with a high-current amplifier, the e:XL-S12 can produce solid output down to 24Hz. The sealed/MDF cabinet is robustly braced to minimize vibration, allowing for accurate bass that’s both deep and musical. With adjustable crossover and volume controls, as well as both line-level (RCA) and speaker-level inputs, setup is flexible for any system. Its auto power-on circuitry and efficient operation keep functionality simple and reliable.

Quality engineering—like a magnetically shielded driver, solid amp board, and Energy’s proven cabinet design—result in bass that’s impactful, tuneful, and free from boom or distortion.

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.
