Energy 2.5-way black floorstanding loudspeaker

CF30 (Black)

Other Sizes:

Audio for the Connoisseur: Energy's CF-30 floorstanding loudspeaker. A single 1" tweeter and two 5.5" woofers combine to deliver 2.5-way audio with the flat, on-axis frequency response and low resonance for which Energy audio is known. While Convergent Source Module technology allows the tweeter and mid-range driver to operate as a single source for enhanced dispersion, Ribbed Elliptical Surround technology dramatically reduces distortion and improves fidelity.

Compact Connoisseur audio

Discover the performance of an Energy Connoisseur floorstanding loudspeaker in a more compact design. While a single 1.0" aluminum-dome tweeter combines with one of the 5.5" mid-range drivers and Convergent Source Model technology to deliver single-source, wide-dispersion high- and mid-range audio, an additional 5.5" woofer teams up with a ported, bass-reflex enclosure design to serve up deep and controlled bass audio. And that's all in addition to the CF-30's high-performance repertoire of design features characteristic of any Energy loudspeaker, including flat on-axis frequency response, wide bandwidth, wide and constant dispersion, and low distortion and resonance. This is audio for the connoisseur.

Convergence upon audiophile sound

With Energy speakers, there's but one source for wide-dispersion, low-distortion, high-performance mid-range audio: the Convergent Source Module. By positioning the CF-30's midrange and tweeter drivers in close proximity to one another, Energy's Convergent Source Module technology makes it possible for the two drivers to act as a single source. The resulting increased overall dispersion creates a wider soundstage with enhanced clarity. Additionally, the independent chambering of the mid-range and tweeter drivers reduces resonance, helping to further curb distortion for higher fidelity audio reproduction.

Ribbed Elliptical Surround

The patented Ribbed Elliptical Surrounds encircling the Energy CF-30's woofer and mid-range driver cones are unlike any other. Because the shape of the speaker surround has been changed to an ellipse, distortion is dramatically reduced. Further, the resulting increased excursion and larger piston area allow for greater efficiency. Finally, because Ribbed Elliptical Surround technology allows for larger cone surfaces and greater peak-to-peak cone movement, an incredible amount of air can be moved by the driver, ultimately making it possible to play lower frequencies with greater fidelity

Bass reflex, it's like an instinct

The design of a variety of a loudspeaker's components is essential to its performance. As important as the design of the driver, amplifier, and circuitry is a floorstander's enclosure, or cabinet. As a vented-enclosure loudspeaker (also known as a bass-reflex cabinet), the Energy CF-30 allows you to experience enhanced low-frequency reproduction out of a smaller enclosure. Vented systems use the sound produced at the rear side of the driver's diaphragm to increase the efficiency of the system at low frequencies by taking advantage of the resonance of ports or vents designed into the enclosure. The air mass in the cylindrical ports resonates in response to the movement of the air behind the diaphragm within the enclosure, similar to the way that the air in a glass bottle resonates when you blow air across its mouth. Your new CF-30's vented design extends low-frequency bass performance and, simultaneously, allows for a more modest enclosure size that won't dominate space in your living room.

Psychoacoustics — Energy is crazy about sound

Energy's passion for and dedication to the reproduction of sound has a long history. Beginning back in the 1970s, Energy participated in nearly a decade of pioneering research into psychoacoustics, attempting to identify those measurable factors listeners associate with a "good-sounding" loudspeaker. Flat frequency response, wide dispersion, and low distortion, they concluded, were the primary factors influencing a listener's perception of the realism of sound produced by a speaker. Consequently, Energy has spent the past thirty years furthering research and applying research-based principles to their engineering and manufacturing of high-performance loudspeakers for the home audio enthusiast.
