CD Series

Overview

Allison’s CD line of Room-Matched speakers is built on the strong foundation of the Designer Series. Sculptural art in cabinet styling, and state-of-the-art acoustic technology, are combined to produce speakers with extraordinary visual effect and a new, higher level of musical accuracy.

It is clear that loudspeaker cabinets, which occupy prominent positions in living spaces, should be as pleasing to the eye as we can make them. But loudspeakers are more than furniture, and technical performance is of overriding importance.

Our primary performance criteria are:

• Uniform(flat) acoustic power output.
• High output capability, enabling the system to reproduce the full dynamic range of digital and analog recordings.
• The lowest possible distortion at all output levels..
• Very broad dispersion at all frequencies.
• Maximum reliability, gained through sophisticated .engineering and rigid quality control.
• Convenience and flexibility in placement.

Convex Diaphragms

A very important factor in our ability to achieve high accuracy is the unique operating principle of our mid-range driver and tweeter, which function effectively as pulsating hemispheres.

Our Convex-Diaphragm tweeter has dispersion more uniform at the highest frequencies than that of any other tweeter made. This is important because it provides flat treble power output, which yields accurate spectral balance and timbre. It also produces sound imaging over a large listening area and gives a realistic simulation of the original space around the image.

The CD series of Allison loudspeakers has refinements in high frequency performance now available for the first time.

• Tweeter distortion, already very low, has been further reduced.
• Power response in the tweeter crossover region has been made even smoother.
• Power handling capability has been increased without compromise in any other aspect of performance.
