L1 model II cylindrical radiator top and bottom

More than just a new type of loudspeaker, L1 portable line array systems provide a completely different approach to live sound. Using proprietary Bose technology, L1 systems combine PA and monitors into a single, highly portable unit that can be positioned behind or to the side of individuals onstage. This novel approach to amplification helps eliminate most of the issues with conventional PA systems—including excessive reverberation and extreme volume on and near the stage. Lightweight, interlocking components help make L1 systems especially easy to transport and set up. And their distinctive vertical loudspeaker enclosures don't require separate speaker stands.

L1M2 What makes An L1 Loudspeaker So Different?
It begins with the shape. L1 Model I and Model II loudspeakers contain a column of closely spaced small drivers mounted in a slim enclosure. This unusual vertical design has significant effects on the sound. An L1 loudspeaker projects sound waves forward and to the sides at nearly 180 degrees, but very little up and down, reducing unwanted room reverberation. Amplified sound also spreads out more evenly across the stage and into the audience, and the volume level drops off much more slowly than with a conventional speaker.

L1 model II powerstand UK

Powerstand for L1® Model 2 system. Integrated power amplifiers in the power stand provide clean, precise amplification for L1® Model 2 system with up to two B1 bass modules or one B2 bass module.


B2 Bass Module

The B2 bass module delivers the most low-frequency output for L1® system users who need more powerful bass for larger audiences. The rugged enclosure encases two 10-inch high-excursion woofers.

A switch on the rear panel offers the flexibility of three output levels, depending on application or preference. The L1® system automatically senses and equalises the chosen setting for optimised performance. The normal setting is ideal for bass guitar or when mic'ing a kick drum. A higher setting is designed for DJ/music playback applications. And the lower setting works well for acoustic guitar and vocals.

Interlocking end caps allow two B2 bass modules to be stacked together. Included slip cover protects the module from dings and scratches during transport.
