LOUD Technologies continually engages in research related to product improvement. New material,
production methods, and design refinements are introduced into existing products without notice as
a routine expression of that philosophy. For this reason, any current LOUD Technologies product may
differ in some respect from its published description, but will always equal or exceed the original

SR1530
The SR1530 is a high-output, horn-loaded, 3-
way, wide dispersion, active sound reinforcement
speaker system. The combination of active on-board
electronics and high-precision transducers allows the
SR1530 to generate high output levels with complete
clarity and high resolution.
The transducers developed for the SR1530 fea-
ture several innovations specifically designed for
this speaker system. The SR1530 is the first speaker
in its class to feature a horn-loaded mid-frequency
transducer. By designing a one piece 90° x 40° horn,
which includes both the mid and high-frequency sec-
tions, the SR1530 takes advantage of several perfor-
mance benefits. First the 6-inch mid-range’s basket
assembly is designed as part of the horn assembly.
It is also designed to function as an optimized
compression chamber, dramatically simplifying the
mid-range assembly. Also, in three-way designs the
mid-frequency horn and the high-frequency horn
are physically pointing to different locations in front
of the box. The SR1530 features an “Optimized
Wavefront” horn design. Unlike typical mid/high
horns, the high-frequency section is positioned to
fire down into the six-inch midrange’s dispersion pat-
tern. This creates a focused, single wave front with
excellent phase and power response characteristics.
The mid-range transducer operates between 700 Hz
and 3,000 Hz eliminating the placement of a cross-
over point in the middle of critical voice frequencies.
Frequencies above 3,000 Hz are reproduced by a 1-
inch exit compression driver. There are two 100 watt
amplifiers for the mid and high-frequency drivers.
The SR1530 deep bass is produced through a
15-inch high-output woofer. The transducer handles
250 watts rms long term. The low-frequency ampli-
fier is an excellent example of the efficiency of active
designs. The amplifier uses a high efficiency, high
current Class G topology to produce 300 watts rms of
power.
The SR1530 frequency response is linear between
45 Hz and 18 kHz. The system processor provides
complete system management of all electronic and
acoustic functions. These functions include electronic
active crossover, electronic phase alignment, elec-
tronic time correction, electronic equalization, and
complete amplifier and component protection. The
system accepts a standard line level signal via an XLR
input connector. There is also a loop out connector
