DESCRIPTION
The TOA SR Loudspeakers are compact integrated
speaker systems made for quality sound reproduction and
easy transportation. Both SR-F1A and SR-L1A are used
with AC-F1/AC-L1 Electronic control units, and work
together to cover the low/high and super-low frequency
range. The AC-F1 and AC-L1 provide a frequency divider,
equalization, correction for component time offset, phase
correction, an active clipping limiter, and a crossover select
switch for SR-F1A ceiling mounting.
The SR-F1A uses the high-power HFD-651 driver and an
LE Series constant directivity horn. Its trapezoidal cabinet
allows arrays to simulate a coherent wavefront single point
source, and its angle of 15° on both sides reduces mutual
high-frequency interference in tightly clustered designs.
The SR-L1A has computer-tuned bass-reflex ports, and two
38cm (15”) woofers with a 72mm (2.8”) diameter voice coil.
Two metal suspension points are on both the top and
bottom, and the rugged APITON plywood enclosure is
finished with shock-resistant FRP (fiber-reinforced plastic).
Neutrik NL4MPR quick connectors are used for both the
SR speakers,
