Bose® L1 Model II System with B2 Bass Module Package
Portable PA system with two-part 24-speaker array, bass module, power stand with amps, cover, and carrying bags
Our take on the Bose® L1 Model II System with B2 Bass Module Package by Crutchfield's Buck Pomerantz
Tall tower of big Bose sound
Bose's L1 Model II loudspeaker system with its B2 bass module will deliver loud, clear sound in an auditorium, or nightclub, for a small acoustic or solo act, or for a DJ performing for audiences of up to 500 people. The package consists of a 24-element articulated speaker array that stretches to more than seven feet high, a bass module containing two 10" woofers, and a power stand with two built-in amplifiers, along with slip covers and carrying bags for all the equipment.
Bose's Spatial Dispersion™ loudspeaker technology gives the L1 Model II more than 180 degrees of horizontal coverage, so audience members off to the sides will hear the same sound as those front and center. In fact, many musicians position their Bose L1 array behind themselves on stage, so they hear exactly the same mix that the audience will hear, eliminating the need for a floor monitor. The B2 bass module fills in the low end of your music, so everyone can really feel the beat.
The L1 Model II's power stand includes two amplifiers, one for the array and one for the separate B2 bass module. The connection cable is included in the package. While not quite "plug and play," the L1 Model II system components all plug together without needing additional wiring, except for a single balanced 1/4" input connection. There are options for adding an external powered sub and for plugging in a Bose ToneMatch digital mixer.
Set up safety feature
The power stand features a safety lever that prevents the L1 array from getting assembled without the power stand's legs being fully extended, for onstage stability. The legs are also linked together so when you extend one, the other legs swing out automatically.
You won't mind toting this PA around. The disassembled components are quite manageable in size and weight. The power stand in its carrying bag weighs under 25 pounds, while the speaker arrays in their carrying bags together weigh under 35 pounds. The B2 weighs in at 45 pounds. And of course the whole system will fit in almost any trunk or back seat for transport.

Overview: The Bose L1 Model II (B2) is a powered, portable two-way loudspeaker system featuring a 24-driver articulated line array speaker tower and a B2 bass module, all of which can be assembled and disassembled quickly for easy setup and portability. Designed to provide full, high-quality sound for an audience up to 500 people, the L1 Model II is ideal for a wide range of indoor applications such as houses of worship, schools, business presentations, mobile DJs, and live music performances.
Speakers: The L1 Model II (B2) features a two-section speaker "tower" that includes twenty-four 2-1/4" high-frequency drivers arranged in an articulated array that stands 84" tall when fully assembled. The system also includes a B2 bass module, with two 10" low-frequency drivers. The combination provides wide, uniform sound throughout the listening area, with 195˚ of horizontal and 0˚ of vertical dispersion. The articulated driver array provides less drop off in sound pressure level, when doubling the listening distance, than a conventional driver arrangement.
Inputs and Outputs: The Bose portable speaker system L1 Power Stand includes a single 1/4" TRS input jack (balanced/unbalanced) that can accept an instrument or other audio source. Additional jacks include:
- Bass Module Out: An NL4 jack is used for connecting the B2 bass module using the included 4-wire bass module cable.
- Bass-Line Out: A 1/4" line-output for running the bass signal to an outboard amplifier or powered subwoofer for additional bass. This can also be used with one of Bose's optional PackLite power amplifier (sold separately) for powering an additional B2 bass module or up to two B1 bass modules (both sold separately).
- ToneMatch port: This RJ-45 port allows digital audio and power connection of an optional Bose ToneMatch audio engine (sold separately).
Controls and Indicators: The top panel of the L1 Power Stand module includes the input and output jacks along with the main power switch and AC power connection. Other controls and indicators include:
- Power/Fault LED: Indicates the power status.
- Blue: System is on.
- Red: System fault is present.
- Trim: This dial adjusts the signal level of the audio input.
- Signal/Clip LED: Working in conjunction with the Trim dial, this
LED indicates the status of the input signal.
- Green: Normal input level.
- Yellow: Input signal is approaching the clip point.
- Red: Input signal is clipping.
Portability: Designed for portability, the L1 Model II (B2) can be broken down into 4 major parts for transportation and stowage.
- L1 Power Stand: Includes its own carry-bag and features 4 retractable legs that can be easily folded up for transportation and unfolded for use. As a safety feature, the Top and Bottom Array extensions can't be installed into the Power Stand until the retractable legs are fully extended, providing maximum stability.
- Bottom and Top Array Extensions: These two pieces simply snap together and each can be transported in their own included carry-bag.
- B2 Bass Module: Features an integrated carry-handle in the top of the enclosure and includes a protective cover.
Tone Match Mixer Compatibility: The Bose L1 Model II (B2) can be used with Bose's optional T4S ToneMatch audio engine (sold separately). This provides additional input channels and digital signal processing for customizing your sound. The T4S audio engine includes a proprietary cable for plugging it into the Power Stand, which provides power for the T4S mixer as well as signal input and output.
