About the Sub1

The Bose Sub1 is a self-powered bass module featuring a 7" x 13" RaceTrack low-frequency driver with a 2" voice coil, delivering a frequency response of 40 Hz to 180 Hz (-3 dB) and extending from 32 Hz to 250 Hz (-10 dB). It provides a calculated maximum continuous SPL of 118.6 dB and peak SPL of 124.6 dB at 1 meter. The subwoofer uses a Class D amplifier with 480 W power output and convection cooling. It includes an onboard mixer with two channels, each accepting combination XLR or 1/4" TRS inputs for mic, instrument, or line level signals, with channel gain control from +10 dB to +45 dB. The Sub1 supports Bose proprietary SubMatch cabling for audio and power, eliminating the need for separate AC power connection when used with compatible systems. Its dimensions are 21.0" H × 10.2" W × 20.8" D (533 mm × 260 mm × 529 mm) and it weighs 34.1 lbs (15.5 kg). The Sub1 is designed for portability and ease of integration with Bose L1 Pro systems, suitable for singer-songwriters and smaller performance setups requiring quality bass reinforcement.
