Product description
The KSLi-SUB and KSLi-GSUB are installation specific cardioid
subwoofers for the KSLi sytsem. They can be used to supplement
KSLi8 and KSLi12 cabinets, either flown (KSLi-SUB) or ground
stacked (KSLi-GSUB).
When the Z5744 KSLi-SUB Mounting frame is used, KSLi-SUB
cabinets can be flown as pure SUB columns or in mixed arrays in
connenction with KSLi-TOP cabinets using the additional Z5745
KSLi-SUB Mounting adapter.
Both cabinets are actively driven, 2-way bass-reflex designs
housing three long excursion neodymium 15“ drivers. Two drivers
face to the front while one driver radiates to the rear of the cabinet.
Front and rear drivers are driven by separate amplifier channels
and operate in independent bass reflex chambers. Through its
cardioid dispersion pattern, this setup avoids unwanted energy
behind the system and greatly reduces the reverberant field at low
frequencies providing highest accuracy in low frequency
reproduction. The frequency response extends from 36 Hz to
105 Hz (33 Hz to 75 Hz - INFRA mode).
The cabinet enclosures are constructed from marine plywood and
have an impact and weather protected PCP (Polyurea Cabinet
Protection) finish. The front and rear of the cabinets are protected
by rigid metal grills. Each side panel incorporates two slots to
accept dedicated lifting pins (T-handles). During setup, these pins
serve as a temporary lifting aid and can be inserted and locked
when needed.
Four rubber feet prevent cabinet movement and protect the bottom
panel against scratching. Correspondingly shaped recesses in the
top panel of the cabinet prevent cabinet movement when stacking
KSLi-GSUBs or KSLi-SUBs.
The KSLi-SUB cabinet incorporates front and rear rigging strands
while the KSLi-GSUB comes without any rigging components and is
intended for ground stacked purposes.
Rigging components and arrays
Cabinets are mechanically connected using the rigging strands on
both sides of the cabinet front and a central strand at the rear of
the cabinet. All necessary rigging components are mounted on the
cabinet and fold out or slide out when needed.
A detailed description of the rigging components is given in the
respective rigging manuals.
