Energy Connoisseur CF-30 2.5-Way Tower Speakers

A pair of Energy Connoisseur CF-30 compact floorstanding speakers — a well-engineered 2.5-way tower that delivers genuine full-range sound from a remarkably slim footprint, in very good condition.

The CF-30 is part of Energy’s well-regarded Connoisseur series and represents the kind of thoughtful Canadian speaker engineering that the brand built its reputation on. The 2.5-way configuration deploys two 140mm (5.5″) woofers with Energy’s Ribbed Elliptical Surrounds — a design that increases surround linearity and reduces distortion at higher excursion levels — crossed over at 1.6 kHz and 2.0 kHz respectively to a 25mm (1″) hyperbolic aluminum dome tweeter. The 2.5-way topology means both woofers handle bass together while only one operates into the midrange, a configuration that delivers better bass output and lower distortion than a conventional 2-way could achieve at this cabinet size. The front-firing bass reflex port extends the low-frequency response to a genuine 43 Hz — more than capable of producing convincing bass in small to medium-sized rooms with or without a subwoofer.

At 90 dB sensitivity and an 8-ohm nominal impedance, the CF-30 is a confident and easy load for any amplifier in the 20–200 watt range. Standing just 36 inches tall with a slim 7.1-inch wide footprint, these towers disappear gracefully in rooms where a conventional full-size floorstander would feel imposing, yet they consistently deliver sound that surprises listeners expecting compact-speaker limitations. The high-gloss black baffle with black ash cabinet sides gives the CF-30 a clean, purposeful appearance that presents well in any home theatre or two-channel setting. Gold-plated 5-way binding posts on each speaker accept single-wire or bi-wire connections.

These speakers have been thoroughly inspected and tested to confirm full functionality.

Weight: 30.8 lbs (14.0 kg) each

For a clean hookup, this pair pairs naturally with our Custom Speaker Cable Builder. Because the CF-30 uses dual 5-way binding posts and supports bi-wiring, buyers who prefer a tidy single-wire connection may also want our Bi-Wire Speaker Bridges, Gold Plated Banana Plugs, and Gold Plated Spade Connectors.

Because the CF-30 is a modern tower design with threaded inserts, it is also a straightforward candidate for IsoAcoustics GAIA III or GAIA III Neo isolators for buyers who want to explore a cleaner, more controlled presentation.

Although these towers stay well clear of oversize freight territory, we still pack them seriously for the trip in 275 lb-test double-wall packaging. If you’d like to see how carefully we handle gear before it heads out the door, have a look at our packing and unboxing video.

A Energy Connoisseur classic — slim, room-friendly floorstanders with genuine full-range performance, surprising bass reach, and a clean, purposeful presentation that works equally well for music and home theatre. Very good condition and fully tested.

Backed by Radique Audio’s Bumper-to-Bumper Warranty and our Perpetual Trade-Back Program, you can purchase with confidence.

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.
