Affordable, reliable, high quality sound

The JRX218S is driven by a massive JBL 18" woofer with a cast frame and 3" voice-coil. The JRX200 series 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 JRX200 speakers. This means we can apply efficient, high-volume production methods and purchase materials at the lowest cost. That's how JRX200 delivers unprecedented value.

Rugged enclosure

The rugged enclosure is constructed from 19 mm (.75 in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency performance. The enclosure is covered in black carpet.

Durable design

Non-resonant, all-steel handles are used along with an attractive 18-gauge hexagon perforated steel grille to protect components from damage.

Top mounted pole mount receptacle

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.
