Harman-Kardon II manual Introduction, Technology

INTRODUCTION

The Infinity Modulus II Home Theater System is a compact, efficient, universal satellite, center channel and subwoofer system that is ideal for reproducing multichannel audio and home theater sound. With their versatile design, the satellite speakers can be placed virtually anywhere on shelves or stands, or mounted on a wall using the supplied base. The center channel can easily be placed on top of, or on a shelf below, the television. The powered subwoofer delivers tremendous bass performance from a compact, easy-to-place design.

About This Manual

To start enjoying your new Modulus II Home Theater System, read and then follow all instructions listed in this guide, as well as those found in the owner’s manuals of associated components in your audio system. Save all instructions for future reference.

TECHNOLOGY

Modulus II loudspeakers incorporate several innovative technologies that, when implemented by our exceptionally talented engineers 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 (CMMD™)

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 patented CMMD 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, CMMD 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.

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 Modulus II 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 Modulus II subwoofer can be adjusted to tame any problematic room-bass resonances

below 80Hz.
