XSLi8/XSLi12 loudspeaker

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: 40D

Product description

The XSLi8 is an installation-specific 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 XSLi Flying frame is used, up to 24 XSLi8 cabinets can

be flown in vertical columns in tension mode rigging, producing an

80° constant directivity dispersion pattern in the horizontal plane.

When the XSLi Top mounting frame is used, up to 12 XSLi8

cabinets can be flown in tension mode rigging.

The XSLi12 line array loudspeaker is acoustically and mechanically

compatible with the XSLi8 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 slot that accepts dedicated lifting

pins (T-handles). During setup, these pins serve as a temporary

lifting aid and can be inserted and locked when needed.
