CONSTANT CURVATURE LINE ARRAY
JBL VRX SERIES LOUDSPEAKERS
JBL’s VERTEC® Series Line Arrays lead the industry in large venue sound reinforcement. While intended for smaller venues than
VERTEC, the VRX900 Series Constant Curvature Line Arrays are designed and built to the same high standards and uses the same
advanced, concert-proven drivers. JBL’s VRX900 Series speakers deliver extraordinary power handling, clarity, flexibility and, of
course, stunning JBL sound in an attractive, easy to handle and affordable package.

A couple of system examples for the 8-inch VRX928LA and the 12-inch VRX932LA/P have been chosen in order to demonstrate the
most asked questions:
1. HOW LARGE of a crowd does a system cover? 2. HOW FAR does it throw? 3. HOW LOUD does it get?
e following selections are based on the most common combinations of VRX900 line array systems. e applications shown,
although generic, will be satisfactory under most conditions. However it cannot substitute an in depth evaluation based on exact
conditions of a specific situation. All examples provide at least 105 dB SPL, which is a common target for general music, and provide
a very homogeneous (within 6 dB) coverage for a given audience area per number of speakers.

may be suspended using the two M10 eyebolt attachment points
provided on the cabinets. A minimum design factor of 7:1 is main-
tained for all speaker configurations at or below those indicated in
the table.
