Using R-18i as Surround Sound Loudspeakers
R-18i is the only loudspeaker on the market that provides the listener a choice of both
direct or a diffuse dipole radiation pattern.
With our innovative DPC
TM
(Dispersion Pattern Control) Technology, the Radia R-18i
provides an unprecedented level of freedom in choosing and optimizing the dispersion
pattern for surround sound presentation. It also provides important flexibility in the loud-
speaker’s mounting location.
The R-18i utilizes BG’s patented PDR wide band driver that operates as a dipole dtrans-
ducer. A dipole is a driver with a very shallow profile that radiates sound to its front and
back with little to no engery to the sides.(See Figure 2 below)
Sound is radiated
equally in both
directions along
the knob’s handle,
to the front and
the back of the
planar transducer.
There is very little
or no sound
radiated in the
directions to the
left and the right
from the handle
arrow (to the sides
of the planar
transducer)
