Technology, Ceramic Metal Matrix Diaphragms C.M.M.D

TECHNOLOGY

Intermezzo Series loudspeakers incorporate several innovative technologies that, when implemented by exceptional engineering talent after hours upon hours of subjective listening evaluations, result in a loudspeaker that realistically and accurately reproduces the signal source with minimal distortion and coloration.

Ceramic Metal Matrix Diaphragms™ (C.M.M.D.™)

For decades, loudspeaker engineers have known that the ideal transducer should be stiff, yet light, and have high internal damping (damping is a material’s ability to absorb energy). Infinity’s C.M.M.D. transducer is a significant advance in transducer technology. Ceramic, a class of material new to loudspeakers, offers better performance than other materials. Ceramic is stiffer than metals and lighter than plastics and typical composite materials; it also offers improved damping. These ceramic-based transducers take us a giant step closer to the ever-elusive “ideal transducer.”

In tweeters, C.M.M.D. technology offers stiffness and damping superior to that of traditional metals and soft-dome materials. In woofer and midrange applications, it offers accurate pistonic operation over the entire frequency range of the driver, completely eliminating coloration due to cone breakup and dramatically reducing distortion. And when ceramic-metal-matrix diaphragms are exposed to moisture, sunlight or extreme temperatures, their performance does not deteriorate.

In addition to ceramic diaphragms, all the transducers incorporate magnetic shielding and rigid cast-frames that, through our FEA computer modeling and scanning-laser-vibrometer measurements, have been optimized to reduce resonances.This ensures minimal distortion and incomparable performance.

Amplifier

BASH® is an amplifier-power-supply technology that increases efficiency by reducing power dissipation in the output section. The BASH topology uses a high-efficiency, fast-response, switch- mode power supply that provides the main voltage rails for a linear Class-AB amplifier. By varying the output of the power supply with the audio signal being amplified, a constant voltage drop across the output transistors of the linear amplifier can be maintained. This means that the power dissipation in the output transistors is greatly reduced.

The result is an extremely efficient audio amplifier that does not compromise audio performance.
