Description

The L1® Compact portable line array system is a powered
loudspeaker system designed to provide wide, uniform sound
coverage and easy setup. Spatial Dispersion loudspeaker
technology combines proprietary Bose® technologies to deliver clear, powerful sound throughout
the entire listening area – even off to the extreme sides. The interlocking components are easily
transported and eliminate the need for external speaker wires and stands.

The system offers a built-in, two-channel mixer with XLR, 1∕8" (3.5 mm) TRS, stereo RCA, and ¼" TRS
phone jack compatibility. The L1 Compact system is well-suited for professional applications such as
music playback, speeches and A / V sound reproduction.

Engineers’ and Architects’
Specifications

The system shall be a multiple driver, full-range
portable loudspeaker system with internally
supplied power amplification and active
equalization for multiple operating modes
as follows:

The transducer complement shall consist of six

2.00" (51 mm) high-excursion drivers mounted in
a curved Articulated Array
with an integral 8" (203 mm) low-frequency driver
mounted in a ported bass enclosure. The loud­speaker array shall be wired in a series/parallel
configuration.

The nominal horizontal beamwidth of the
loudspeaker shall be 180°, and the vertical
coverage shall be 40.° The system’s power stand
shall incorporate a ported venting system for the
low-frequency driver, tuned for 65 Hz. The power
amplification for transducers shall be supplied by
the integrated power stand providing 130 W
continuous pink noise, band-limited from 65 Hz
to 14 kHz (-3 dB).

The input connectors of the power stand module
shall consist of one XLR with equalization for a
dynamic handheld microphone, one ¼" TRS with
selectable ToneMatch® signal processing for acoustic
guitar with piezo pickup, stereo RCA, and one

1

∕8" TRS receptacle. The output connectors of the
power stand shall consist of one ¼" balanced
TRS or unbalanced TS and two RCA unbalanced
phone plugs.

The enclosure of the power stand shall be
constructed of polypropylene materials. The
extension and array shall be constructed of ABS
materials. In collapsed tabletop mode, the
system’s outer dimensions shall be 16.5" H x

13.25" W x 16.75" D (418 mm x 339 mm x 426
mm). Its weight shall be 24.6 lbs. (11.2 kg). In
extended operating mode, the system’s outer
dimensions shall be 78.5" H x 13.25" W x 16.75" D
(1995 mm x 339 mm x 426 mm). Its weight shall be

29.2 lbs. (13.3 kg).

The system shall be capable of two operating
modes; collapsed tabletop or extended position
by integrating height-extension modules.

The loudspeaker shall be the Bose® L1® Compact
portable line array system.
