JBL JRX 218S, passive subwoofer 18", 350Watt, 4Ohm

The JBL JRX 218S is a Passive PA Subwoofer, offering 350 Watts, with an 18" Woofer. JRX 200 delivers the performance and prestige JBL is known for at an affordable price point. To meet these conflicting design goals, we looked at every element of the speaker system design. We kept everything that makes a speaker perform and sound its best and we eliminated things that don't. With performance, value and popular price points, we are going to be building a lot of JRX 200 speakers. This means we can apply efficient, high-volume production methods and purchase materials at the lowest cost. That's how JRX 200 delivers unprecedented value. The JRX 218S is driven by a massive JBL 18" woofer with a cast frame and 3" voice-coil.
