2. GENERAL DESCRIPTION

Developed for the mobile sound reinforcement applications, TOA's SR-F1D and SR-L1B make up a speaker

and subwoofer system which features high power handling capability, high quality and durable construction.

• The SR-F1D can reproduce both low and high frequencies (bi-amp operation), while the SR-L1B clearly

reproduces super-low frequencies. Both systems are used in conjunction with a digital processor.

• The SR-F1D reproduces low frequencies with excellent transient response thanks to its high-efficiency

30 cm woofer with large 20 cm diameter magnet.

• The SR-F1D's driver employs a titanium diaphragm and features high sound quality and high power handling

capability. Its constant directivity horn (60° horizontal x 40° vertical) has a smoothed cross-sectional area and

provides a uniform sound field and smooth sound quality.

• The SR-L1B's 38 cm woofer consists of a strong magnetic circuit employing a large 20 cm diameter magnet

and a 72 mm diameter long voice coil. This combination permits ultra-linearity down to super-low frequencies

while realizing high power handling capability.

• The enclosure is constructed of high-strength Apitong plywood. Since the outside surface is covered in

polyurethane resin, the speaker also features high durability to stand up to rough handling when used on the

road.

• Neutrik NL4MPR input connectors ensure quick and accurate system field installations.

• The SR-F1D features flying hardware (ring/stud pan fittings) installed on its top and bottom. The bottom

surface is also equipped with built-in nuts for mounting on an optional stand.

• Because the sides of the SR-F1D's enclosure are angled at 15°, when multiple speakers are arranged side-

by-side, they can be oriented in a radial array, which helps suppress mutual interference at high frequencies.
