MartinLogan Announces Mosaic Floor Standing Main/Surround Hybrid Electrostatic Loudspeaker

Electrostatic loudspeaker technology company MartinLogan® has announced the introduction of its compact new Mosaic™ floor standing loudspeaker.

The new model offers key MartinLogan technology and features, including ATF (advanced thin film) transducers, ultimate crossover design, high-excursion, high-resolution woofers, curvilinear wood cabinetry, and dipole radiation, in a small package (40 inches tall) and at an affordable price. The Mosaic falls at the low-cost end of the MartinLogan product spectrum, available immediately at a retail price of $1,995 per pair (US).

The Mosaic is designed for use as a stereo main loudspeaker, home theater main or effects channel speaker, in a wide range of room sizes and configurations. Compact and décor-friendly, the Mosaic is supplied with tool-less binding posts for effortless cable attachment and management.

In addition to ATF transducer technology, MartinLogan’s design team developed the Mosaic utilizing a new woofer and cabinet based on the MartinLogan Clarity loudspeaker (released January 2003).

ATF™ (Advanced Thin Film) Transducers Provide Clarity, Detail and Resolution

In order to achieve the rigorous MartinLogan standards for detail, clarity and resolution, and yet permit a compact cabinet, high-resolution ATF transducers became the first building block for the new Mosaic.

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 (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, and is a major contributor to the linearity and sonic superiority of both ATF and electrostatic MartinLogan thin film transducers.

ATF diaphragms are constructed of extremely low mass Dupont Kaladex® PEN (polyethylene naphthalate), a material chemically similar to the low-mass PET (polyethylene 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 extremely low-distortion levels with superior resolution.

Mosaic Shares Key Technologies from MartinLogan Ultimate Speaker Models

Mosaic’s state-of-the-art, 8-inch, high-resolution woofer uses the same motor, cone and chassis structure as the innovative Clarity loudspeaker to deliver a precise low-end with accuracy and authority.

Mosaic’s state-of-the-art Vojtko™ crossover is designed and manufactured with the same meticulous attention, care and precision as those found in MartinLogan’s ultimate loudspeaker products.

Mosaic’s cabinet consists of multiple laminates sonically welded for extreme rigidity. This acoustically inert curvilinear wood cabinet, provides not only audiophile grade high-performance, but also enhances visual integration with any home environment. It is available in three distinctive cabinet finishes (natural cherry, dark mahogany and black).

Dipole Design For A Realistic, Open Sound Stage

The audio industry has long recognized that late arrival reflective information significantly enhances the ambient nature of sound reproduction. This ambient reflective information dramatically contributes to a realistic, “you are there” listening experience. MartinLogan’s dipole radiation pattern (radiating out of phase information from both the front and back) ideally interacts with your listening environment to create this realistic sound stage. We have contoured Mosaic’s radiation pattern to emulate the same dipole characteristics as our world standard setting electrostatic technology, resulting in the same outstanding sound staging and 3-dimensionality.
