2.1 Intended use
NOTICE!
Only operate d&b SL-Series loudspeakers with the specified and
correctly configured d&b amplifiers, otherwise there is a risk of
damaging the loudspeaker components and the directional
characteristics of the system cannot be achieved.
Applicable d&b amplifiers: D40 | D80
Product description
The XSL8 is a line array loudspeaker for small to medium-scale
sound reinforcement applications. It also serves as a supplement to
other SL-Series systems for fill and/or delay purposes.
When the XSL Flying frame is used, up to 24 XSL8 cabinets can be
flown in vertical columns in either compression and/or tension
mode rigging producing an 80° constant directivity dispersion
pattern in the horizontal plane.
When the XSL Top mounting frame is used, up to 12 XSL8 cabinets
can be flown in tension mode rigging.
The XSL12 line array loudspeaker is acoustically and mechanically
compatible with the XSL8 and provides a 120° horizontal
dispersion.
The cabinets are 3-way designs, both housing 2 x 8" neodymium
forward LF drivers, 2 x 6.5" neodymium side firing LF drivers, one
horn-loaded 6.5" MF driver and 2 x 1" exit HF compression drivers
with 2" coils mounted to a dedicated wave shaping device. The
cylindrical wave segments of each cabinet couple without gaps
and sum up coherently. Splay angles between adjacent cabinets
can be set in the range from 0° to 14° in 1° increments.
The cabinets are driven by two channels of the applicable d&b
amplifier which provides dedicated processing functions for the
front LF and passively crossed-over side LF and MF/HF sections.
All components are arranged symmetrically around the center axis
of the cabinet to produce a perfectly symmetrical dispersion
pattern. This setup allows for a very smooth crossover design with
a well defined overlap of adjacent frequency bands resulting in a
very consistent and accurate horizontal dispersion.
Due to the arrangement of the forward and sideward LF drivers in
combination with their processing functions, the directivity is
maintained across the entire frequency range.
The frequency response extends from 60 Hz to above 18 kHz.
The cabinet enclosures are injection molded (ABS Polycarbonate)
and have an impact and weather protected 2K finish. The front
and side panels of the cabinets incorporate a rigid metal grill
backed by an acoustically transparent and water repellent fabric.
Each side panel incorporates a handle while two additional
handles are provided at the rear.
