Energy CF-70 Floor-standing Speakers

Design

The speakers are a full 3-way design with two 6.5 inch woofers and a 5.5 inch midrange and like other Energy speakers are highlighted by the brushed aluminium phase plug "spikes" instead of a dust caps for the mid and woofers. The woofer and midrange also feature Energy's "Ribbed Elliptical Surround" which changes the shape of the speaker surround to reduce distortion and increase excursion.

The midrange is combined with a 1 inch aluminium tweeter in Energy's "Convergent Source Module". The CSM concept locates the tweeter and mid close together to assist with sound dispersion while isolating them in separate chambers within the speaker. Both are also technologies borrowed from Energy's Top of the line Veritas speakers. Finally there's a 2" bass reflex port "rounding" out at the bottom of the stack. The cardboard tube behind the plastic flared port is dark grey which can be visible in certain lighting conditions and stands out a bit against the black gloss baffle.

The cabinets come with one finish: a black ash textured woodgrain vinyl that wraps the speaker's left, top and right sides. The back panel is also woodgrain and the seam is slight and would not be noticeable unless you were looking for it. The front baffle is a high gloss finish which was much more resistant to fingerprints than I had expected. While piano gloss looks nice to me I'm not sure it will be a trend that keeps looking good five years down the road. There are no floor spikes available but the speakers were stable enough with their relatively thin feet, hunkering down well into the thick carpet in my HT. Being fairly tall vs their width I would not recommend having them out in the open with kids / large pets without additional bracing of some sort. Cabinet construction is more solid than expected at this price point. The speakers are equipped with dual, gold plated, 5-way binding posts capable of bi-amping or wiring. The front speaker grills attach via 8 posts and hide the gloss baffle almost completely if it is not to your liking. The grill posts themselves are on the speaker as opposed to the grill which can look a little strange with the grills off. Not liking grills and liking the look of the glossy baffle I left them off for the duration of the testing.
