(330) 277-5000

Bose's most advanced L1 system for an audience of up to 500. With a 24-speaker articulated line array providing 180 degrees clear, even coverage, it combines the best sound reproduction with easy transport and setup. Designed to work with the T1 ToneMatch® audio engine, which provides four additional inputs, Bose's largest library of ToneMatch presets and a complete suite of studio-class effects and processing.

What's in the box:

  • L1 Model II power stand with chord
  • Power stand carry bag
  • L1 Model II cylindrical speaker radiator (top and bottom)
  • Loudspeaker carry bags
  • Single B2 bass module with chord
  • Bass Module slip cover
  • T1 ToneMatch Audio Engine
  • T1 ToneMatch face plate and carry bag
  • T1 ToneMatch pillar mount and CAT5 Ethernet cable cable for connection to system

Sound advantages—only from Bose

The system's breakthrough loudspeaker produces wide, uniform sound coverage of nearly 180 degrees—onstage and throughout an audience of up to several hundred—with little dropoff in volume and tone.

The Model II system also features Articulated Array speaker technology for better tonal balance. The loudspeaker's 24 vertically mounted drivers are precisely angled to create clearer highs and more consistent tone in the room. Even people off to the sides of these stage speakers enjoy well-balanced, detailed sound.

Full, flexible bass

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.

You can power one B2 bass module on a single L1 power stand. And the optional PackLite® power amplifier lets you add a second B2 bass module for maximum low-end power.

Easy and efficient

The L1 Model II power stand weighs only 24 pounds, and its four retractable legs make it easy to transport and set up. The power stand also has a simplified control section; the single line-level input can be used with instruments, mics, mixers, laptops, MP3 players or DVD systems.

All of the system's components are also built to handle the road. The loudspeaker has a rugged, reinforced grille, and each package includes padded carrying bags for major components.

Multichannel flexibility

The optional T1 ToneMatch audio engine adds four more channels, so you can expand the system and connect additional instruments and microphones. You can also use the ToneMatch engine to fine-tune your sound with powerful, proprietary tone-shaping tools.
