Renkus-Heinz SX28‐WR Weather Resistant (WR) SX28
Product Overview
The Renkus-Heinz SX28-WR is a weather-resistant, externally powered dual eight-inch subwoofer built for permanent commercial installations needing compact low-frequency reinforcement in high-humidity or covered outdoor environments. Its twin SSL8-23 woofers deliver output comparable to a single 12-inch sub in a cabinet roughly two-thirds the volume. This passive subwoofer complements Renkus-Heinz full-range loudspeakers in houses of worship, multi-purpose rooms, and commercial meeting spaces.
Product Description
The dual eight-inch SX28 provides power and punch equal to most single 12-inch subwoofers in a cabinet that is two-thirds the volume, making it easy to integrate where space is limited. 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. The weather-resistant (WR) treatment prepares the enclosure and hardware for high-humidity and covered outdoor applications. 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 SX28 can be field-upgraded to a self-powered SA28 using Renkus-Heinz SA-Series amplifier modules.
