TOA Electronics High Performance Subwoofer - SR-C15B
Product Overview
The TOA SR-C15B is a high-performance 15-inch passive subwoofer designed to extend low-frequency output for the SR-C8L and SR-C8S line array speakers. As a dedicated line array subwoofer, it delivers deep, controlled bass for auditoriums, houses of worship, and large multi-purpose rooms where full-range reinforcement is required. TOA recommends pairing it with the DP-SP3 digital speaker processor for optimal crossover and tuning.
Product Description
The SR-C15B uses a 38 cm (15") cone driver in a bass-reflex enclosure to reproduce the low-frequency range that compact line array cabinets cannot cover on their own. With the recommended DP-SP3 parameters applied, it operates from 40 Hz to 400 Hz with a 125 Hz crossover, integrating cleanly beneath an SR-C8 array for music playback, speech reinforcement, and event audio.
The enclosure is fitted with M8 threaded steel plates for secure attachment of optional suspension and stand-mount brackets, and input is provided on both a screw terminal and two Neutrik NL4 sockets for flexible wiring. To build a complete system, pair the SR-C15B with the TOA SR-C8L long-throw line array or browse other TOA line array speakers.
