JBL SUB18 Studio Subwoofer

The JBL SUB18 is a professional-grade studio subwoofer engineered to anchor monitoring systems in control rooms, mastering suites, and serious mixing environments. Its massive 18-inch driver and rock-solid cabinet deliver the low-frequency extension and output capability demanded by sound engineers and mix professionals working with music, film, and broadcast content. This is purpose-built monitoring equipment designed to reveal what's actually happening below 25 Hz—essential for mix decisions that translate across all playback systems.

Subwoofer Performance

The SUB18 extends response down to 20.6 Hz at -10 dB and 23.1 Hz at -6 dB, providing the deep low-frequency articulation critical for mix translation and accurate monitoring. With a maximum peak output of 137 dB SPL and 2000W continuous power handling (8000W peak), this subwoofer delivers powerful, controlled bass reproduction across the full monitoring range without compression or distortion—reliable day after day in professional facilities.
