An engineering masterpiece, Fresco i blends innovative design, advanced materials, and the latest technology to produce signature MartinLogan sound from a compact and versatile package. ATF (Advanced Thin Film) midrange and high-frequency drivers, a precision Vojtko crossover, and proprietary dual long-excursion, low-mass woofers combine to supply astonishing performance in any stereo or multi-channel audio system, whether used as a center, left, right or surround speaker. From top to bottom, Fresco i delivers precision and detail, with firm, agile bass and impressive dynamics.
Fresco i's paintable, super-dense, low-mass cabinet is just 6 inches deep, blending perfectly with wall-mounted flat-panel displays. Each Fresco i comes standard with a low-profile, single-pivot wall bracket that allows vertical or horizontal mounting next to a plasma or LCD display or in any other location. Also standard are Fresco i’s high-gloss Elite Black faceplate and black grill cloth. Optionally available are table and floor stands.
High-resolution ATF drivers (based on RADIA planar technology) approach the clarity and detail of MartinLogan's electrostatic panels while permitting the use of a compact cabinet. Each MartinLogan ATF transducer has a micro-thin, low-mass diaphragm with an ultra-light, etched aluminum conductive surface, suspended between two opposite-polarity, high-field-strength neodymium magnet arrays. When the electrical audio signal from an amplifier passes through the diaphragm's surface, it creates an alternating electromagnetic field that interacts with the fields of the fixed magnet arrays, forcing it back and forth to produce sound waves in the air. The strength and polarity of the diaphragm's field varies according to the audio signal.
ATF transducers and MartinLogan's award-winning electrostatic transducer share several key performance enhancing features that ensure precise, accurate reproduction with vanishingly low distortion. Each ATF transducer diaphragm is sandwiched between and simultaneously driven by magnet arrays of opposing polarity to create an inherently linear push-pull effect similar to that of an electrostat. Another similarity is that the diaphragm is driven uniformly over its entire surface, rather than at just a small contact area as in a conventional cone or dome driver.
