Overview Specifications Brochure Related Products Solutions Latest News & Cases

The DSP1500S is an active subwoofer designed to enhance the low-frequency performance of column speakers and conventional loudspeakers, which often lack depth and impact in the bass range. By delivering powerful and full-bodied low frequencies, it significantly improves overall sound quality and listening experience.


To ensure optimal compatibility with different speakers, the DSP1500S features adjustable input gain, low-pass frequency, and phase control. These flexible adjustments allow precise matching of sensitivity, frequency response, and phase characteristics for balanced and natural sound reproduction.


With its discreet and minimalist design, the DSP1500S blends seamlessly into various environments, making it an ideal solution for venues that require both superior audio performance and refined aesthetics.
