Speaker, Bose L1 Model II system with B2 bass module, 500W

The Bose L1 Model II system with B2 bass module is a portable 500W amplification system designed for musicians, DJs and public speakers. Its slim, articulated line-array loudspeaker provides nearly 180-degree horizontal coverage for consistent tonal balance across the stage and audience. One B2 bass module is included to extend low-frequency output and increase impact for larger audiences.

Advantages

The L1 Model II delivers wide, uniform sound coverage with minimal volume and tonal drop-off over distance thanks to Spatial Dispersion™ and Articulated Array® technologies. The 24 vertically mounted drivers in the cylindrical loudspeaker are angled to produce clearer highs and consistent midrange. The included B2 bass module offers three output settings for flexible bass response, and the system’s interconnecting components fold and pack into padded carrying bags for efficient transport and quick setup.

Suitable for

• Solo musicians and small ensembles performing on stage
• DJs and playback applications for parties and events

How to use

Set up the L1 Model II power stand on a stable surface and unfold its four retractable legs. Connect the top and bottom Cylindrical Radiator loudspeaker sections to form the articulated line-array column. Attach the B2 bass module to the power stand using the supplied cable when additional low-frequency reinforcement is needed. Use the single line-level input and trim control on the power stand to connect instruments, microphones, mixers or playback devices. Adjust the B2’s three-level setting (normal, higher, lower) to match the source (bass guitar, DJ playback, acoustic/vocals) and set levels to avoid clipping.

Usage recommendations

For best coverage, position the loudspeaker column centered on or slightly in front of the performance area so the 180° horizontal dispersion covers the audience. Use the B2’s normal setting for bass instruments, the higher setting for DJ/music playback, and the lower setting for acoustic guitar and vocals. Transport components in the provided padded bags and secure interlocking end caps when stacking multiple bass modules.
