Renkus-Heinz CA118S‐A Self‐Powered Analog, SA1250‐A Amp Module
Product Overview
The Renkus-Heinz CA118S-A is a self-powered 18-inch subwoofer with an analog-input amplifier module, part of the in-stock C Series and a companion to C Series full-range loudspeakers. It provides high-impact sub-bass for permanent commercial installations, pairing an 18-inch high-power woofer with an integrated SA1250-A amplifier module. As a plug-and-play powered install subwoofer, it extends low-frequency reach in auditoriums, houses of worship, and multi-purpose venues without external amplifier racks.
Product Description
The C Series is kept in stock for immediate shipment in black. The 118S subwoofer was developed as a companion to full-range C Series loudspeakers, providing the high-impact sub-bass energy many venues require. Its high-performance woofer uses a 4-inch voice coil, rigid cast-alloy frame, and long-throw magnetic structure. The integrated SA1250 amplifier supplies 1000 watts to the low-frequency section with factory-optimized multi-band peak and thermal limiting, and a built-in low-pass filter eliminates the need for an external electronic crossover. The A model accepts balanced analog input through looping XLR-3 connectors, making it a straightforward self-powered choice where network control is not required. Twelve M10 Universal Mounting points and a 35 mm pole socket support flown and ground-stacked deployment.
