JBL's JRX200 loudspeaker line delivers the level of performance and quality you expect from JBL without cleaning out your savings account. The JRX 218S is a compact passive subwoofer that can add serious power and impact to your PA system.
The JRX218S features a JBL low-frequency 18" driver with a cast frame and massive 3" voice coil in a ported enclosure. It will handle up to 350 watts continuous (or 1400 watts peak), and JBL recommends that you power this sub with an amplifier rated at between 350 and 700 watts. Properly amplified, this subwoofer will bring a whole new dimension to your performance, where the audience hears and feels the low notes.
How low can you go?
JBL built the rugged enclosure from 3/4" medium density fiberboard (MDF), and it's covered in black carpet with an 18-gauge steel grille and non-resonant steel handles. A 36mm pole mounting socket allows the JRX218S to serve as the base for a mid/high speaker cabinet, like JBL's JRX215. The JRX218S offers the performance and durability JBL is known for in a rugged, compact package. See just how low you can go.

Should I get a powered or non-powered sub?
For small-to-medium venue applications, a powered subwoofer will give you the low-end thrust your music deserves. These self-contained systems are designed to get the most output possible from their built-in amplifier and sub. So, when you're shopping, we suggest you pay more attention to the listed sound pressure level (SPL) ratings than the listed wattage ratings. For larger spaces and/or bass-heavy presentations, you'll need the power and projection you can only get from separate amplifier and sub. For a non-powered sub, you can safely use an amplifier whose continuous power output is rated up to double the rated program power capacity of the sub.
