DDR-160 Self-Assembly Kit


Designed and supplied by Stephen R Aizlewood

Loudspeakers are ultimately responsible for the overall sound quality of your audio system. Neither the CD player nor the Amplifier has as strong an influence on the quality of the reproduction.

Good loudspeakers can be very expensive but in many cases you are paying for the aesthetics and the quality of the components has been compromised.

The advantage of buying a kit is that high-end quality is available at a reasonable price.
 






The DDR-160 uses a 100mm full-range driver of very high quality and low distortion for midbass and treble together with a 160mm low frequency unit for superior bass performance. As there are no crossovers in the conventional sense with their inherent problems, only filters, the result is 
a very coherent sound stage with
 excellent imaging and transient response. Clarity and detail throughout the midrange and treble is exceptional due to the point source of  the full-range driver. The tuned reflex enclosure for the low frequency driver provides bass that is both extended and controlled without boom or boxiness. The overall result is a compact speaker that offers a natural yet exciting listening experience that can be enjoyed for long periods without fatigue.















The DDR-160 kit includes all the parts required to build a pair of speakers and 16 precision CNC machined cabinet panels for accurate and easy assembly.
