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.
3. FEATURES
• 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 the DP-0206 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 Apiton plywood. Since the outside surface is covered in FRP
(glass fiber-reinforced plastic), 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 (Aeroquip 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.
