DIATONE 2S-3003

Commentary

This speaker system was developed as a monitor standard for the Hi-Vision era by integrating all the technologies of Diatone.
While inheriting the basic design of the 2S-305 model, we pursue a wide range, low distortion, and high input-resistant efficiency.

A 32 cm cone type woofer is installed in the low range.
A 3-axis woven aramid honeycomb diaphragm is used for the diaphragm. In this diaphragm, aromatic polyamide aramid fiber with extremely high rigidity and excellent vibration damping characteristics is changed from the conventional vertically and horizontally woven fabric to 3-axis woven fabric to obtain strength in all directions. By using this skin material as a diaphragm with honeycomb structure, dispersion resonance at high input is suppressed, and low distortion and excellent response are realized.
The magnetic circuit uses the Alnico magnet version of A. D. M. C. -m (Advanced Magnet Circuit-music), which boasts high magnetic flux density. The A. D. M. C. -m focuses on the fluctuation of magnetic flux in the magnetic circuit and has a structure that cancels the AC magnetic flux from the voice coil. This minimizes the movement of the center of the voice coil with respect to the magnetic pole at large amplitude and enables clear and quick start playback.

A 5 cm cone type tweeter is installed in the high range.
B which is pure boron for the diaphragm₄C is adopted. B₄In order to maximize the potential of the material for the C-diaphragm, we have adopted the plasma spray method, which is an ultra-high precision molding method that enables thin film and light weight, and expanded the playback band toward the mid-range while trying to reach the limit point of the high-range.

In order to prevent the transmission deterioration of the woofer unit, the network section is composed of only tweeters.

The enclosure uses a rounded baffle that is also used in the 2S-305 to prevent the diffraction phenomenon of sound waves.

We measured the overall characteristics of each unit in an anechoic chamber and attached it as a test report to guarantee the quality.

There were special wagon-type stands sold separately and special cables using stress-free 6N high-purity oxygen-free copper.
