MartinLogan has just announced the compact new Fresco on-wall/off-wall left-center-right-surround loudspeaker featuring a selection of installation options, room friendly aesthetics, crossover design, high-excursion, high-resolution bass drivers and ATF (advanced thin film) transducer technology.

Incorporating MartinLogan’s new ATF (advanced thin film) transducer technology, the Fresco is ideal for most sound reproduction applications from 2-channel to multi-channel music as well as home theater. Designed to match any MartinLogan product in both looks and performance, the Fresco functions as main, center or surround channel(s), either on wall or off wall in both horizontal and vertical orientations. A unique 'on wall/off wall' switch allows listeners to tailor Fresco's acoustic equalization to any of these installation options.

The Fresco comes standard with a low profile, single pivot wall bracket, allowing horizontal and vertical on-wall mountings alongside plasma screens or any other location throughout the listening environment. Optional installation solutions include a floor stand, center channel stand, shelf stand, and a universal multi-pivot on-wall bracket.

Available in a variety of faceplate and grill cover options, Fresco matches most plasma screens and the complete MartinLogan product line. Easily removable, custom faceplates will also be available to integrate with contemporary, architectural interiors. In addition, Fresco’s high-density molded cabinet is paint-ready for custom installation.

Under the hood of the Fresco lies a Vojtko crossover, designed and manufactured with the same attention and care as those found in MartinLogan’s ultimate loudspeaker products. Complete system engineering of Fresco’s high excursion, extremely low-mass bass drivers, in combination with a specifically tuned chamber and electronic filtering, result in high levels of power handling and bass from this compact product.

High-resolution ATF transducers became the first building block for the new Fresco. The MartinLogan ATF transducer consists of a micro-thin, low mass diaphragm with an ultra-light, etched conductive aluminum surface suspended between two high field strength neodymium super magnet arrays. When an electrical current (i.e. a music signal) passes through the etched aluminum on the diaphragm’s surface it is simultaneously pulled towards one of the neodymium arrays and pushed away from the opposing. When the direction of current is reversed the diaphragm is simultaneously pushed and pulled in the opposite direction, thus producing sound. This concept is called push-pull.

ATF diaphragms are constructed of low mass Dupont Kaladex PEN (polyethylene naphthalate)—a material chemically similar to the low-mass PET (polyethelene terathylate) film used in MartinLogan's generation 2 electrostatic transducers, yet capable of handling the high thermal requirements needed for stable magnetic thin film operation. Full surface drive capabilities allow this durable, low mass diaphragm to remain discretely sized, yet achieve low-distortion. To maximize installation options, ATF transducers are completely shielded to eliminate any deleterious effects on nearby equipment.

The Fresco is now shipping and is available for $995 each.
