GENERAL DESCRIPTION

SR Series loudspeakers from TOA are compact integrated
speaker systems for use in sound reinforcement applica-

tions with an emphasis on quality sound and durability,
and for easy transportation.

The SR-F1 speaker system and the SR-L1 super woofer
system provide a wide frequency response and high pow-
er handling capacity. The system can be composed with

the SR-F1 to reproduce the low/high frequency range and
the SR-L1 to reproduce the super-low frequency range.
These speakers are used with the AC-F1 or the AC-L1

Electronic control unit.

The SR-F1 reproduces transcient response characteristics

in the low frequency range more one ranking up magnet

than that of 30cm (12") woofer used up to this time.

The driver unit for the SR-F1 is used the HFD-651 high

power driver unit improved for the system, and LE Series
Constant directivity (CD) horn ensures a uniform sound
dispersion pattern (60° horizontal by 40° vertical).

The 38cm (15") woofer of SR-L1 ensure ultra-linear to
super-low frequency range with a 72mm (2.8") diameter
voice coil driven by powerful double magnets. Bass reflex

ports are tuned to the optimum conditions by computer
allowing the woofer to provide maximum performance.

The SR-F1 provides each two fixing metals for the suspen-
sion (Aeroquip made) on top and bottom boards.

The enclosure is made by APITON plywood, and the rug-
ged enclosure finished with FRP (Fibre reinforced plastic)

coating is shock-resistant to transport it on the road.

Cannon EP-4-14 is used for input connectors enabling to
perform the quick and secure system up at site. The SR-F1
is designed to change the pin number combination from

the SR-L1. If the SR-L1 connector is wrongly connected to
the SR-F1, sound is not reproduced.

The SR-F1 is designed to make an angle of 15° at both
sides of the enclosure. When lining up two speakers or

more, they are in all directions and mutual interference is
reduced in high frequency range.
