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 that of 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 transducers 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.

Room-Friendly Acoustical Design

Driver quality is not the only requirement for exceptional performance. Infinity’s engineers understand that the room in which the loudspeaker is placed can greatly affect its performance. To ensure that Intermezzo Series loudspeakers will sound exceptional in even the most unexceptional listening environment, Infinity has developed the proprietary Room Adaptive Bass Optimization System™ (R.A.B.O.S™). . With a single band of parametric equalization, the Intermezzo 1.2s can be adjusted to tame any problematic room bass resonances below 80Hz.

We hope you enjoyed this brief introduction to the technology of Intermezzo loudspeakers. If you would like to further explore their technology and design, please ask your Infinity dealer for the C.M.M.D. and R.A.B.O.S. White Papers.

1.2s specifications

The Infinity 1.2s is a revolutionary advancement in the world of audio technology, specifically designed for audiophiles and sound enthusiasts who demand superior sound quality. This state-of-the-art speaker system boasts a range of features that ensure impeccable audio performance, making it a popular choice among professionals and casual listeners alike.

One of its standout characteristics is its exceptional frequency response. The Infinity 1.2s is engineered to deliver a wide frequency range, allowing it to reproduce both deep bass and crisp treble with remarkable accuracy. This enables listeners to experience music as it was intended by the artists, with each instrument and vocal nuance clearly pronounced.

Incorporating advanced driver technology, the Infinity 1.2s features a combination of woofers and tweeters that work in harmony to create a balanced sound profile. The woofers are crafted from high-quality materials to minimize distortion while maximizing bass response, ensuring that low-frequency sounds are powerful yet controlled. Meanwhile, the tweeters employ cutting-edge technology to deliver high frequencies that are both detailed and smooth.

Another significant technology embedded in the Infinity 1.2s is the innovative crossover design. This sophisticated crossover network effectively divides audio frequencies between the woofers and tweeters, which enhances the speaker's overall performance by ensuring that each driver operates within its optimal range. The result is a seamless transition between low and high frequencies, producing a cohesive sound that is rare in many consumer-grade speakers.

The build quality of the Infinity 1.2s is also noteworthy. Constructed from durable materials, the cabinets are designed to minimize resonance and vibrations, which can muddy sound quality. This focus on sturdy construction not only enhances audio fidelity but also contributes to the longevity of the speakers.

Furthermore, the Infinity 1.2s is equipped with versatile connectivity options. It can easily adapt to various audio setups, whether wired or wireless, offering compatibility with a range of devices and systems. This flexibility makes it a great choice for both home theater systems and high-fidelity audio playback.

In conclusion, the Infinity 1.2s stands out in the crowded audio market due to its impressive sound reproduction capabilities, advanced technologies, and rugged construction. Whether for professional use or personal enjoyment, these speakers offer a remarkable listening experience that is sure to satisfy even the most discerning audio enthusiasts.
