Bose Sub2 L1 PRO Series Powered Portable Bass Module

The Bose Sub2 is a high-performance, powered bass module designed to enhance portable PA systems with deep, rich bass response down to 37 Hz. It features a unique 10" × 18" high-excursion neodymium RaceTrack driver that delivers the same output as a conventional 15" woofer but in a much slimmer enclosure. This space-saving design makes it easy to transport and set up, while still delivering professional-grade low-end reinforcement for both music and speech.

Ideal for use with the Bose L1 Pro32 system, the Sub2 connects via proprietary SubMatch technology, providing both power and audio through a single cable. Multiple Sub2 units can be stacked to increase output or configured in Cardioid Mode for directional bass, which focuses the output forward and reduces rear-facing noise. It also includes flexible connectivity options and mounting features, making it a versatile solution for performers, DJs, and AV professionals.
