■The new 'HS Series' employs newly developed transducers with an advanced magnetic circuit design that controls and equalizes the flow of magnetic field lines. By reselecting and optimizing the acoustic components, we have achieved a dramatic improvement in playback capabilities.
'HS5' 'HS7' 'HS8' The HS Series employs a newly developed, high-performance 1-inch dome tweeter and a thick wave guide designed to minimize resonance. This combination extends the reproducible frequency range to 30kHz, enabling accurate and smooth reproduction of high frequencies. The newly developed dedicated woofer, which uses a large magnet, has excellent response and high input resistance, delivering low frequencies with a controlled feel and minimal distortion at any volume. Furthermore, acoustic components such as the woofer ring and basket have been reselected and optimally designed to achieve well-defined low frequencies.
■The HS Series enclosure is designed to thoroughly eliminate unnecessary resonance and improve the accuracy of original sound reproduction. In addition to using MDF material, which has high rigidity and uniform acoustic properties, The three-sided joints, a technique long used in wooden construction for their superior strength, are used for the joints. By seamlessly combining the irregularities on the wood joint surfaces, the strength is incomparable to that of simple surface joints, and noise caused by resonance is reduced.
■Air vortices around the bass reflex port induce air vibrations inside and outside the port, generating noise within the port. The new HS Series employs the latest fluid sound control technology to visualize, analyze, and control airflow and sound in the port design. The new port minimizes air vortices, reducing audible noise and meeting the demanding requirements of music production environments.
■The rear panel features ROOM CONTROL, which corrects the emphasis on low frequencies when the speaker is placed near a wall, enabling accurate monitoring. It also features HIGH TRIM, allowing for precise balance adjustment to suit the room and application. The input terminals include both XLR and TRS phone jacks, providing flexible support for a variety of use cases, including output from mixers, keyboards, and audio interfaces.
