BOSE L1 Model 1S-L1 S1 powerstand

The vertical configuration of the system’s small, closely spaced drivers allows the BOSE 1S-L1 S1 powerstand system to project sound forward and to the sides—delivering 180-degree coverage—but very little up and down, reducing unwanted reverberation. This produces consistent tonal balance as sound spreads more evenly across the stage and into the audience, and the volume level drops off much more slowly than with a conventional speaker.

Unique Bose® technologies enable the system to serve as both PA and monitor. It can be positioned behind or to the side of the performer—and you hear just what the audience hears. You’re in control, and there’s no need for conventional monitors, mixers and PA systems.

The three components of the L1 Model 1S system—upper array, lower extension and power stand—connect quickly and easily without the need for separate speaker stands. Setup and breakdown take just minutes. And everything stores neatly into the included carry bags, making transport easy, too.

The high-performance B2 bass module delivers greater low-frequency output when you need more powerful bass for larger audiences. The module includes three settings for increased flexibility. The normal setting is ideal for bass guitar or when miking a kick drum. A higher setting is designed for DJ/music playback applications. And the lower setting works well for acoustic guitar and vocals.

The optional T4S or T8S ToneMatch® Mixers adds additional channels, so you can expand the system and connect additional instruments and microphones. You can also use the ToneMatch mixer to fine-tune your sound with powerful, proprietary tone-shaping tools.
