The flagship of Energy’s Connoisseur range, built in Toronto by a company whose voicing grew out of the National Research Council’s listening work in Ottawa. Two 8-inch aluminium-polypropylene woofers and a cloth-suspended aluminium dome, crossed at 1,800 Hz and reaching 28 Hz — genuinely full-range, so most rooms will not want a subwoofer under them. At 93 dB it runs happily on 30 watts. High-gloss black, made in Canada, 57 lb each. Very Good condition. Pair — pickup in Kanata, or we deliver.

Description

Design and Drivers

Made in Canada, the Energy Connoisseur C-8 is a flagship 3-way vented tower from Energy Speaker Systems — a Toronto-founded company whose engineering legacy rivals that of any speaker manufacturer in the country, and whose Connoisseur series represented the pinnacle of their consumer floorstanding range.

The C-8 is a substantial, serious loudspeaker. The cabinet is a tapered, front-ported 3-way vented design housing an aluminium dome tweeter with cloth suspension, flanked by two 20.3cm injection-moulded aluminium/polypropylene woofers with rubber surrounds and polypropylene diaphragms — driver materials that Energy chose for their stiffness-to-mass ratio and long-term stability. The crossover is set at 1,800 Hz, and the combination of driver quality, cabinet bracing, and Energy’s decades of NRC-informed acoustic research produces the smooth, extended, and dynamically capable performance that earned the C-8 a 4.8 out of 5 average rating across 75 user reviews on AudioReview — an exceptional result for a floorstanding speaker at any price.

At 93 dB room efficiency and a nominal 8-ohm impedance (4.5-ohm minimum), the C-8 is an easy and rewarding load for any quality amplifier or receiver from 30 watts upward — yet its 300-watt RMS power handling means it will scale gracefully with high-powered amplification in larger rooms. Frequency response extends to 28 Hz (-3 dB), giving these towers genuine full-range capability that eliminates the need for a subwoofer in most listening rooms. The high-gloss black finish is striking and well-executed, and at 57 lbs each these are solidly, impressively built.

Condition

This pair is in very good condition and has been thoroughly inspected and tested to confirm full functionality.

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.
