CLS Column Loudspeaker
SLIM, COLUMN SPEAKERS FOR PUBLIC ADDRESS AND BACKGROUND MUSIC
KEY FEATURES
Elegant, low profile design
Directional vertical line array characteristics
Exceptional sound clarity
Long distance sound projection
High sensitivity for efficient powering
PRODUCT DESCRIPTION
The CLS series loudspeakers are a miniature column array specifically designed for the needs of distributed public address
and background music. The array characteristic narrows vertical dispersion, increasing the throw, and minimizing
unwanted reflections and coverage. The CLS sound columns offer a slim line, visually appealing speaker ideal for spaces
sensitive to clean architectural design. Perfect for reverberant applications that require clarity, articulation such as
transportation centers, cathedrals, and other public areas.
The CLS series comes in two driver sizes and up to four standard lengths. The CLS2 version uses 2” drivers and a tweeter,
and is available in 4 lengths. The CLS3 version uses 3” drivers and a tweeter and is available in three lengths. The larger
speaker size and the longer lengths display characteristics of lower frequency response, higher maximum output, and
tighter vertical coverage angles. The CLS Series can also be ordered in custom lengths and powder coat colors.
