DIATONE DS-26B

Commentary

This 3-way speaker system is designed with an emphasis on matching between the cabinet and unit and sound connection.

A 25 cm cone type woofer is installed in the low range.

The mid-range is equipped with a 10 cm cone type squaker.
This unit is an acoustic load type, and the rear part of the diaphragm is completely sealed. The air chamber is filled with sound absorbing material, so there is no interference with the woofer.
The magnetic circuit uses a barium ferrite magnet.

A 3-cm dome type tweeter is installed in the high range.
The diaphragm of this unit is a newly designed polyester resin diaphragm which is damped with micron glass wool to prevent abnormal vibration. The edge is also treated with sandwich damping to prevent sound from being emitted from the edge.

The enclosure is an edge-less cabinet with no protruding edge around the baffle plate. The enclosure has a sufficient volume for the size of the woofer. It drives the woofer without waste by finding the optimum value of volume and low sound reproduction limit frequency.
In addition, we focus on the vibration of the box, which has not been taken into consideration so far, and determine the reinforcement position of the box based on sufficient calculation to improve sound quality.
