TECHNICAL SPECIFICATIONS SB850F
DESCRIPTION
A dedicated subwoofer system with 2x 18-in transducers in a
trapezoidal enclosure. Each driver is in its own optimally
vented subenclosure. “F” flown array version features handles,
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
