An engineering masterpiece, Fresco bends innovative design, advanced materials, and the latest technology to the task of producing wide-range, MartinLogan sound from an astonishingly compact and versatile package. ATF™ (Advanced Thin Film) midrange and high-frequency drivers, a precision Vojtko™ crossover, and dual long-excursion, low-mass woofers combine to supply the performance. Let appearances not deceive – this is not some wimpy wall-mount speaker. From top to bottom, Fresco delivers electrostatic-like smoothness, precision, and detail, with firm, agile bass and impressive dynamics.
Fresco's gas-assist molded, super-dense, low-mass cabinet is just 6 inches deep, blending perfectly with wall-mounted flat-panel displays. Its sweeping lines and vivid textures complement any décor, from traditional to modern. Easily interchangeable faceplate and grille options provide tremendous flexibility in tailoring the speaker's appearance, and the faceplate can be painted to match any interior. Each Fresco 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. Optionally available are a table stand, a floor stand, and a universal multi-pivot wall bracket.
Based on RADIA planar technology, high-resolution ATF™ drivers approach the clarity and detail of our 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.
Like our electrostatic panels, ATF drivers are push-pull transducers: When the diaphragm's field polarity is the same as that of the magnet array on one side, pushing them apart, it is the reverse of the polarity on the other side, pulling it toward that opposing array with exactly the same force. This mode of operation is inherently linear. Another similarity to electrostats 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. These two characteristics ensure precise, accurate reproduction with vanishingly low distortion.
The diaphragm substrate is Dupont Kaladex® PEN (polyethylene napthalate). This material is chemically akin to the PET (polyethylene terathylate) film used for the diaphragms of our CLS™ Generation 2 electrostatic panels, but capable of handling the heat generated by the current passing through an ATF diaphragm's thin aluminum skin.
Fresco is suitable for use in any stereo or multi-channel audio system, mounted either on- or off-wall. And it blends well with other MartinLogan speakers in both sound and appearance, which allows mixing and matching to meet specific installation requirements.
Each Fresco comes standard with low-profile, single-pivot wall bracket that allows vertical or horizontal mounting next to a plasma or LCD display or in any other location. Optionally available are a table stand and floor stand (available from your local dealer or the Xtatic Shop).
Available in a décor-friendly selection of faceplate and grill cover options, Fresco's perfectly matches any plasma screen as well as the complete MartinLogan product line. Easily removable, custom faceplates are also available to integrate with contemporary, architectural, high-value interiors. In addition, Fresco's high-density molded cabinet is paint-ready for any custom installation.
Carefully hand-built using only the finest polypropylene capacitors and air-core coils, the crossover employ's MartinLogan's proprietary Vojtko topology for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.
An acoustic contour switch tailors Fresco's low-frequency response appropriately for on-wall or off-wall placement.
By eliminating cone flexure, aluminum diaphragms help our advanced-technology woofers achieve the very low distortion necessary for proper blending with MartinLogan electrostatic panels.
