EV Reference ONE
Michael Kraske developed this model around the idea of a wide-band, closed cabinet speaker. Knowing about the tonal balance and richness that a full-range speaker can reproduce, not willing to accept the lack of bass and presence of high percentage of distortion.
So the paper-cone, symmetrical drive mid-woofer is accompanied by a 1“ tweeter and 12“ long-throw subwoofer. The mid-woofers slices-cone prevents effectively cone breakups, so it is playing from 50Hz and blending over gently to the tweeter creating a speaker with full-range characteristic - but with punchy bass down to 25 Hz and extended treble smooth as silk. As always with Credo Audio speakers, we achieved linear impedance and a high efficiency (of 87.6 dB), making it an easy load for amplifiers.
