GS90A

Recently, the frequency bandwidth of recordable high tones on packaged media such as CDs has been extended, and it is now possible to experience actual sound quality with extended recording bandwidth within the conventional CD format, such as 96 kHz oversampling, super bit mapping, and 1-bit Σ△ modulation methods.

Furthermore, next-generation media standards and formats such as Super CD and DVD-Audio have been proposed, and various research and development efforts are underway to expand the playback bandwidth in line with these standards and formats.

As music information recorded on packaged media becomes wider bandwidth, the playback system must also extend the playback bandwidth.

The GS90A is a super tweeter that allows anyone using an existing bookshelf or floor-type system to easily expand the reproduction of ultra-high frequencies. Its extended frequency response up to ultra-high frequencies, sufficiently high output sound pressure level, and fine, crisp sound quality make it widely compatible with a variety of speaker systems.

The super tweeter unit uses a hemispherical horn flange shaped horn machined from aluminum alloy with a natural directivity pattern.

In addition, the ultra-light aluminum alloy ring diaphragm and high-performance magnetic circuit with ALNICO magnets reproduce high quality sound with high efficiency, excellent frequency response and directivity characteristics, and without any peculiarities.

The built-in network circuit with continuously variable attenuator is simply connected to the combined speaker system with a cable.

The exterior case is made of thick wood with natural wood veneer finish side panels. It has a high-grade paint finish in subdued tones.
