The JBL JRX 218S is a compact single 18" subwoofer with a cast frame and a 3" voice coil. 350 W (continuous), 1400 W (peak) power capacity.  The JRX218S subwoofer has been designed to supplement and extend low frequency performance of full-range systems, in live sound and music playback applications. The JRX218S is driven by a massive JBL 18" woofer with a stamped steel frame and 3" voicecoil. It’s rated at 350 watts (continuous) and 1400 watts (peak), based on JBL Professional’s 100 hour extended life test.

The rugged enclosure is constructed from 19 mm (.75 in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for durability and improved low-frequency performance. The enclosure is covered in black carpet. A top mounted, cast aluminum 35 mm pole mount receptacle can receive an optional SS3BK pole to facilitate use of the JRX218S as a base for a midhigh speaker cabinet.
