Radiation Boundary Integrator
All three Control 47 models (47C/T, 47LP & 47HC) incorporate
JBL's proprietary patent-pending conical Radiation Boundary Integrator (RBI)
which is adapted from the groundbreaking VERTECŪ Series of line array loudspeakers.
This unique JBL patent-pending innovation combines a large diameter high-frequency waveguide with low-frequency projection apertures that work in tandem to provide a
seamless integration of coverage between the two coaxially-mounted drivers.
The result is extremely consistent pattern control and coverage.
Well-controlled wide coverage from the Control 47C/T and Control 47LP allows the use of fewer
speakers, substantially reducing overall system cost, while providing more consistent sound throughout
the listening space. Narrow, focused coverage from the Control 47HC allows use in high ceiling locations
and highly reverberant spaces.
