DIATONE DS-20B

Commentary

Two way bookshelf speaker system.

A 20 cm cone type woofer is installed in the low range.
This unit realizes a rich low sound by adopting a shallow curved cone and matching with the cabinet.

A 5 cm cone type tweeter is installed in the high range.
This unit uses a mechanical load type and realizes stable sound quality with low distortion and good resolution.

The dumped bassreflex system is used for the enclosure.
In this method, the bass reflex is tuned to the frequency that gives the best transient response. At the same time, the bass reflex port is dumped with a specially selected polypropylene sound-absorbing material to prevent distortion from increasing due to an increase in the woofer amplitude in the low and heavy range below the tuning point.

A 20 cm woofer unit a 20 cm woofer unit using a shallow curved cone with excellent directivity is used.

A 5 cm cone type tweeter is used for the high range.
It is a mechanical load type in order to obtain sound quality with low distortion and high resolution.

The enclosure uses the dumped bassreflex method as a special method for small-capacity bookshelf speakers.
For tuning the bass reflex, the frequency at which the transient response is best is selected, and the bass reflex port is damped with a specially selected polypropylene sound-absorbing material to achieve a low frequency with good damping and little distortion.

The enclosure was available in two color variations.
