MartinLogan Crescendo

“The Crescendo is a very appealing product… And those who are serous about audio will love the neutrality and overall sound quality of the Crescendo… Definitely a way swankier take on the usual wireless speaker. And it looks really cool, too. ” — Brent Butterworth, Technology

It doesn’t come cheap, but you have to remember you’re also getting a work of art that you’ll be proud to display.” — Bob Ankosko, Sound & Vision

Powerful Performance

At the core of the Crescendo is an advanced 24-bit, 48 kHz DSP-based preamplifier in conjunction with a powerful class-D closed-loop 100 watt (140 watt peak) amplifier. Crescendo’s amplifier creates powerfully detailed sound from a custom designed front-firing 5 x 7″ matte black polypropylene cone woofer with extended throw drive assembly in a non-resonant asymmetrical chamber format. Low frequencies are blended with two of MartinLogan’s high-performance Folded Motion tweeters for a big, room-filling experience. The signature Folded Motion tweeters utilize extremely low mass diaphragms that “squeeze” air, and require significantly less excursion than the typical 1-inch dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
