MARTINLOGAN EXCLUSIVES

Curvilinear Line Source (CLSTM)

Since the beginning of audio, achieving smooth dispersion has been a problem for all loudspeaker designers. Large panel transducers present even more of a challenge because the larger the panel, the more directional the dispersion pattern becomes.

Full range electrostats have long been one of the most problematic transducers because they attain their full range capabilities via a large surface area. It looked as if they were in direct conflict to smooth dispersion and almost every attempt to correct this resulted in either poor dispersion or a serious compromise in sound quality.

After extensive research, MartinLogan engineers discovered an elegantly simple solution to achieve a smooth pattern of dispersion without degrading sound quality. By curving the horizontal plane of the electrostatic transducer, a controlled horizontal dispersion pattern could be achieved, yet the purity of the almost massless electrostatic diaphragm remained uncompromised. After creating this technology, MartinLogan developed the production capability to bring it out of the laboratory and into the market place.

You will find this proprietary MartinLogan technology used in all of our products. It is one of the many reasons behind our reputation for high quality sound with practical usability. This is also why you see the unique “see through” cylindrical shape of all MartinLogan products.

ForceForwardTM Bass Alignment

Acheiving smooth bass response in your room has long been one of the most "troublesome" issue in dealing with the placement of any loudspeaker. The reflected low-frequency energy from the front wall re-combines with the energy projected forward into the room causing "booming" or "lean" bass, typically a null at 50Hz and a peak at 100Hz.

With the introduction of the Prodigy, the MartinLogan engineering and design teams have resolved this issue with an innovative technology, ForceForward. Two horizontally opposed, phase timed proprietary MartinLogan drivers work together to reduce the destructive reflected energy from your front wall, resulting in easy placement for clean, pure, powerful bass response.

Vapor Deposited Film

The diaphragm material used in all MartinLogan speakers employs an extremely sophisticated conductive surface that has been vapor deposited on the polymer surface at an atomic level. A proprietary compound is vaporized then electrostatically driven into the surface of the polymer film in a vacuum chamber. This process allows an optically transparent surface adding no mass to the diaphragm that is extremely uniform in its surface resistivity characteristics. This uniform surface resistivity controls the electrostatic charge on the diaphragm surface and regulates its migration. As a result, no discharging or “arcing” can occur.

Transducer Integrity

All MartinLogan transducers begin with two pieces of high-grade, cold rolled steel. These steel pieces are then custom perforated and insulated with a unique composite coating. This proprietary coating insulates the stator to three times its actual needed working voltage and gives the Prodigy a wide margin of safe operation. In addition to the electrical insulation properties, this coating also provides the Prodigy with a durable, attractive finish that dampens the steel to prevent ringing. These pieces are then sandwiched with our exclusive vapor deposited diaphragm and spacers into a curved geometry, and bonded together with aero- space adhesives whose strength exceeds that of welding.

The result of these advanced technologies is a transducer that is attractive, durable, highly rigid, well dampened, and neutral.
