Energy RC70 (Black)

single 3-way black RC-70-series floorstanding speaker

Other Sizes:

It's tough to say what makes the Energy RC-70 floorstanding speakers so great. It could be the clear highs and powerful lows from the 1" tweeter or 6.5" kevlar woofers. Maybe it's the way the 5.5" midrange brings everything together, creating a range that can handle precise, musical sound or layered movie audio. Of course, possibly the beautiful finish is what makes these so unique. Or it could be how all that combines into a floorstanding speaker that's ready to rock as part of your complete home theater system.

Priced and sold as a single speaker.

The lowdown

You don't have to be a connoisseur to know these speakers rock — that happens the moment you hear them. These speakers are pure power, pure style — and Pure Energy. And, they're as cool to look at as they are to hear — all on a gloss black base and in a cabinet that looks cool anywhere. Ideal for medium-large-size rooms where you want plenty of power and volume.

Pop the hood

Pop the grille and what you see is Pure Energy: from the crystal-clear 1" dome tweeter to the 6.5" Kevlar™ woofers and a 5.5" midrange, there's enough power to slam you back in your chair. Using Kevlar for cone construction gives the woofer both light weight for quick reaction and superior rigidity to handle increased output levels. Ribbed Elliptical Surround technology cuts distortion, so all you hear is audio the way it was meant to sound.

Ribbed elliptical sound

The patented Ribbed Elliptical Surrounds that encircle your RC-70's woofers are unlike any other. By changing the shape of the speaker surround to an ellipse, rather than the traditional "half roll," distortion is reduced dramatically. Side benefits include increased excursion and larger piston area, allowing for greater efficiency. The cast basket woofers also feature this technology, allowing the surround to stretch and contract as it moves, eliminating dimpling.

Aluminum dome tweeters

Aluminum dome tweeters combine the wide dispersion characteristics and superior off-axis response of a dome design with firm, but lightweight aluminum. A staple of audiophile-grade speakers, the aluminum dome tweeter features low distortion, flat frequency response and smooth acoustic dispersion.

Frequency response and why you care

Frequency response is how well a speaker reproduces every frequency in a human's audible spectrum. Since most humans can hear from approximately 20Hz to 20kHz (20 cycles per second which is deep bass, to 20,000 cycles per second which is very high frequencies), this measurement depicts how wide of a spectrum the speaker can reproduce. It is important to note that although some speakers can play a wide range of frequencies, the most important fact is ensuring it plays all frequencies at the same level. A speaker that, for example, reproduces more high frequencies than low frequencies will sound "bright" in comparison to speakers with a smooth response.
