The world's first subwoofer uses the "HVT method," which enables ultra-thin speakers.

By adopting a double-sided drive system, we pursue unprecedented natural low-frequency reproduction
The world's first subwoofer uses the "HVT system," which has made the speaker ultra-thin. We have achieved a revolutionary ultra-thin design with a total height of only 4.5cm, something that could not be achieved with conventional subwoofers. Additionally, due to the unique structure of the double-sided drive HVT unit, a comfortable bass sound that smoothly connects to the sound located in front of the vehicle spreads throughout the vehicle.
