the high-frequency driver is provided via an
integrated MOSFET circuit that actively
monitors and controls the power delivered
to the compression driver. There is also a
circuit breaker button on the rear control
panel designed to protect the woofer from
excessive power. The breaker “sees” the
amplifier signal being delivered to the
woofer and opens when the combination of
amperage and voltage exceeds the maxi-
mum rated power levels. The breaker
switch can be reset by pressing the button.
The rear control panel features both a
1/4˝ speaker jack and a Neutrik® Speakon®
connector, wired in parallel. The S500 cabi-
net is constructed using both multi-layered
plywood and pressure-injected structural
resin. The top and bottom sections both
have handles for easy movement and relo-
cation. There is an integrated pole-mount
on the bottom of the enclosure. In addition,
there are two, three-part cast-aluminum
handles on each side of the enclosure as
well as a full size, oval-punched, weather-
resistant steel grille.
phase plug. The result is frequency response
linearity and extension never before avail-
able for a product in this class. The S500 also
features a low-distortion, high-output horn
design developed to provide the correct
power response and phase alignment char-
acteristics at the crossover frequency. With
the resulting 75º x 65º dispersion pattern,
the S500 provides very open, natural sound
reproduction at extreme output levels.
The S500 produces deep bass through a
15-inch high-efficiency RCF® precision
woofer. The magnetic structure designed
for the woofer motor is responsible for the
system’s resulting high sensitivity of 100 dB
(1 watt@1 meter). More importantly, the
high-efficiency motor provides an extraordi-
nary amount of force that provides complete
control of the cone mass. This type of control
allows the woofer to deliver extended bass
response and to reach the mid-frequency
crossover point efficiently.
The S500 frequency response is linear
between 75 Hz and 20 kHz. Protection for

SERVICE INFORMATION
Service outside the United States can be ob-
tained through local dealers or distributors.
If your S500 needs service, please follow
these instructions:
1. Call Tech Support at 1-800-258-6883,
