The Grimm Audio SB1 is a flagship active subwoofer system that uses proprietary Digital Motional Feedback technology to deliver highly accurate low-frequency reproduction with significantly reduced distortion. Designed primarily for the LS1 series loudspeaker systems, the SB1 extends system performance to 20 Hz while maintaining the transparency and precision required for professional monitoring and critical listening.
Each subwoofer cabinet is positioned beneath an LS1 loudspeaker and works with the system’s DSP-controlled crossover to create a seamless three-way configuration. A dedicated mono version is also available for use with third-party audio systems.
