JRX218S Subwoofer + RWM3300UA Wireless Microphone System

This package pairs a JBL JRX218S 18-inch passive subwoofer with a Rockville RWM3300UA dual handheld UHF wireless microphone system, covering both the low end and the vocal chain for a live event in one order. The JRX218S delivers 1,400W peak power down to 34 Hz, with a carpeted MDF enclosure and a top-mounted 36mm pole receptacle that lets it serve as the base for a mid-high cabinet.

The RWM3300UA adds two cardioid handheld microphones with 200 channels of UHF selection across the 500 to 599 MHz band, so presenters or performers can find a clean frequency even in a crowded RF environment. A dual-filter design limits feedback and interference, individual volume control lets each mic be balanced separately, and OSA technology automatically locates the clearest available channel. Rack-mount LCD displays on both the transmitter and each microphone show battery status, with up to 8 hours of runtime per charge. Together, the subwoofer and mic system suit DJs, presenters, and small venues that need reliable bass and wireless vocals without renting separate gear.
