Acoustic Zen Crescendo MkII loudspeakers

The Crescendo loudspeaker is a three-way full range loudspeaker built on the same component, cabling and cabinet quality of the Adagios. It incorporates two 5 inch midrange drivers, two 8" woofers and one horn-loaded ribbon tweeter all in a transmission line design. Like the Adagios, the upper half of the Crescendo is a D'Apolito MTM configuration, featuring two 5 inch midrange "underhung" voice coil ceramic-coated drivers around a 2 inch horn-loaded ribbon tweeter. In addition, the bottom of the Crescendo tower features two 8 inch "underhung" voice coil ceramic-coated woofers. Now in its second generation, the Crescendo Mark II features drivers with larger magnet assemblies for even higher linearity and heavier and reinforced cabinets for even lower resonance and overall lower distortion. The resulting sound is remarkably clear, full, accurate and lifelike.

The crossover has also been upgraded. The Absolute Sound review of the original was a rave. They sum with: Acoustic Zen’s Robert Lee has crafted a magnificent transmission-line speaker, truly a perfectionist labor of love. The Crescendo is eminently musical and supremely well-integrated from top to bottom. It certainly pushed of all my emotional buttons and is currently my favorite box speaker under $30k. Make no mistake about it: The Crescendo is a fantastic value at its asking price. An enthusiastic five-star recommendation! In the Positive feedback review they said: "The Crescendos are full-range, top to bottom, blockbusters that are astoundingly flat right at 20Hz and tip-toeing up to (and quite literally past) 20kHz;" "The integration of each driver in this three-way transmission line "under hung" system is spooky: very few speakers, at any price, achieve the sonic coherence so effortlessly delivered here;" I am the original owner of these phenomenal loudspeakers and they have always resided in my dedicated listening room free from smoke, pets, kids, direct sunlight and dust, etc. Speakers are finished in the highly desirable high gloss Rosewood finish and are always covered when not in use. I've visited many audio shows over the past several years and have always been amazed at the incredible performance of the Crescendo Mk2 loudspeakers and rated them in the top 3 at each show regardless of price. The Crescendo's are easy to drive and mates well with solid state or tubes. Probably the last speaker you will own unless you can afford the Maestro's. Speakers mate well in either small or larger rooms. The speakers are in excellent condition with no known scratches, dings or blemishes. These speakers have been babied and a steal at my asking price. I rarely get a chance to listen to music nowadays as I own my own company and rarely have any free time. I will be listing other equipment over the next few weeks here on AudioGon and other audio sites. I also have a 12' run of Acoustic Zen Double Barrel speaker cables that offer a perfect synergy with the Crescendo's. I would be willing to work out a package deal. Low ball offers will be kindly ignored. Thank you for your consideration. Cheers!
