DIATONE DS-25BmkII

Commentary

A speaker system announced as an improved version of the DS-25B.

A 25 cm cone type woofer is installed in the low range.
This unit uses a spin-finished die-cast frame with sufficient thickness and strong structure to improve resolution by eliminating the natural vibration of the frame itself.
A damping ring made of special synthetic rubber is attached to the voice coil to function as a mechanical filter and improve the characteristics near the crossover frequency.

A 5 cm cone type tweeter is installed in the high range.
A sub-frame of orifice structure is installed in the chamber of this unit, and resolution is improved by suppressing resonance, and clear high sound is realized by center cap of titanium dome and frame of high rigidity structure.

The network section is equipped with core coils with low transmission loss and metalized polyester film capacitors with low distortion, thereby reducing distortion of the playback bandwidth.

Equipped with 4-step switching type level control for the high frequency band.

The enclosure has a symmetrical unit layout, which makes the pattern of the directional characteristics of the tweeter at the listening point symmetrical and improves sound localization.
In addition, distortion is reduced by adopting a rectangular wooden duct for the bass reflex duct. In addition, by adopting a dispersion resonance type for the internal structure, vibration is suppressed by dispersing the resonance mode, and box rumbling phenomenon is suppressed.
The exterior has a pecan finish, and the secondary RUNNET has a mesh finish.
