Koss CM-1030 loudspeakers

 

 

The Koss CM/1030 represents the culmination of theory, technology and engineering experience in loudspeaker design. First, Koss engineers set the parameters for frequency response, efficiency and cabinet size. From these initial specifications, the Koss Theory developed specific design characteristics that include a 10-inch woofer, a mass aligned dual port system,, a parallel midrange system, and both a tweeter and treble tweeter that feature a unique acoustic transformer. And to mesh the system into an unbelievably beautiful entity, the CM/1030 uses a quasi second-orede crossover network. Once you've heard the Koss CM/1030 , we think you'll agree that no 4 bandpass system available today even comes close in performance.

 

Although much has been attributed to the speed and efficiency of the modern computer, there is little that any computer can accomplish without first having the specific scientific equations and data necessary to achieve specified goals. In the case of the new Koss CM loudspeaker systems, the modern computer allowed Koss engineers to perform the massive and complex audio engineering calculations required in using network synthesis to establish the engineering parameters for all CM systems.

Nevertheless, whereas the computer may have simplified the workload, it was still the genius of electrical and audio engineers and even, in the case of the cabinet designs, the brilliance of structural engineers, that made this remarkable new generation of loudspeaker systems possible.
