Product Overview
The Renkus-Heinz SX118 is an externally powered 18-inch subwoofer built for permanent commercial installations that require deep, controlled low-frequency reinforcement. Built on a compact, integration-friendly cabinet with an SSL18-11 woofer, this passive subwoofer complements Renkus-Heinz full-range loudspeakers in auditoriums, houses of worship, and multi-purpose venues. Large ports keep its forceful bass free of port noise across the operating range.
Product Description

The SX118 delivers the power and punch of an 18-inch woofer in a cabinet that is easy to integrate into any project. Large ports ensure forceful bass is never marred by chuffing or fluttering noise. Connections are made through two Neutrik Speakon NL4 connectors wired in parallel with a terminal strip, and a crossover frequency of 120 Hz or lower is recommended for system integration. Sixteen M10 Universal Mounting points allow the cabinet to be flown with M10 eyebolts, while the M20 pole adapter, recessed handles, and available casters support portable and ground-stacked use. The SX118 platform can be field-upgraded to a self-powered SA118 using Renkus-Heinz SA-Series amplifier modules.
