Energy Connoisseur CF-50 2.5-Way Tower Speakers — Made in Canada

A pair of Made-in-Canada Energy Connoisseur CF-50 compact floorstanding speakers — a highly efficient, four-driver 2.5-way tower from one of Canada’s most respected loudspeaker manufacturers, in very good condition.

The CF-50 is the standout performer of Energy’s Connoisseur series, and its 96 dB sensitivity rating immediately sets it apart from virtually everything else in its class. At 96 dB, the CF-50 requires only a fraction of the amplifier power that a typical 87–88 dB speaker needs to achieve the same listening level — one watt produces what most speakers need eight watts to match. This makes the CF-50 an ideal partner for lower-powered vintage amplifiers and receivers, while its 20–250 watt power handling range means it scales equally well with high-powered modern electronics. The front-firing bass reflex port extends low-frequency response to a genuine 39 Hz, producing room-filling bass authority that belies the speaker’s slim, 7.1-inch wide cabinet.

The 2.5-way four-driver topology is the key to the CF-50’s combination of sensitivity and tonal balance. Three 140mm (5.5″) woofers with Ribbed Elliptical Surrounds — a surround geometry that reduces distortion at higher excursion levels — handle the bass and lower midrange together, with two woofers rolling off at 1.2 kHz while the third continues operating up to the 2 kHz tweeter crossover. This arrangement provides generous cone area for low-frequency output while giving the upper midrange the focus and control of a single dedicated driver. The 25mm (1″) hyperbolic aluminum dome tweeter delivers clean, extended highs with a wide dispersion characteristic that keeps the top end consistent across a broad listening area. Energy’s Convergent Source Module positions the tweeter in close proximity to the upper woofer, acting as a near-point source to improve spatial coherence and imaging.

The high-gloss black baffle with black ash cabinet sides and gold-plated 5-way binding posts give the CF-50 a clean, purpose-built appearance that suits home theatre and two-channel installations equally well. Bi-wire and bi-amp capability via the dual binding posts allows those with suitable electronics to extract additional performance from the design.

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

For a clean hookup, this pair pairs naturally with our Custom Speaker Cable Builder. Because the CF-50 uses dual 5-way binding posts and supports bi-wiring or bi-amping, 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-50 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 under our oversize threshold, 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 Made-in-Canada Energy Connoisseur classic — four drivers, exceptional 96 dB sensitivity, and genuine 39 Hz bass extension in a slim, room-friendly cabinet that performs well beyond what its footprint suggests. Fully tested and ready to anchor a high-performance home theatre or two-channel system.
