DESCRIPTION
A dedicated subwoofer system with 2x 18-in transducers in a
trapezoidal enclosure. Each driver is in its own optimally
ventedsubenclosure.“F” flown arrayversionfeatureshandles,
flytracks and internal counterweights.
APPLICATIONS
The SB850 high output Stadium Array subwoofer integrates
with KF Series Stadium Array systems to form extended range
flown arrays. 19-position flytracks and internal counter-
weights ensure a “dead hang.” Tuned enclosure venting ex-
tends LF response and minimizes driver strain. MX Series
processors extend LF response and safeguard against cone
excursion damage. Six Year Warranty.
Applications include:
Concert Tours
Major Televised Events
Corporate Events

ARCHITECTURAL SPECIFICATIONS
The sub bass loudspeaker systems shall incorporate 2x 18-in
LF transducers mounted in separate vented subenclosures
tuned for optimum low frequency response.
System frequency response shall vary no more than ±3 dB
from 32 Hz to 150 Hz measured on axis with appropriate
signal processing. The loudspeaker shall produce a Sound
Pressure Level (SPL) of 99 dB SPL on axis at 1 meter with a
power input of 1 Watt, and shall be capable of producing a
peak output of 138 SPL on axis at 1 meter. The loudspeaker
shall handle 2000 Watts of amplifier power (AES Standard)
and shall have a nominal impedance of 4 (2x 8) Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in black catalyzed poly-
urethane. Input connectors shall be one each male and fe-
male AP4. A total of 4x 19-position flytracks (2 each top and
bottom) shall be provided. The front of the loudspeaker shall
be covered with a vinyl coated perforated steel grill backed
with open cell foam to protect against dust.
The sub bass loudspeaker shall be the EAW model SB850F.
