JBL SRX828S, 18 Inch Dual Passive Subwoofer System

The JBL SRX828S is a dual 18” subwoofer for concert, touring, or installed use. Featuring a wide stance for splaying top boxes, indexing feet for stacking in both the standard and cardioid position, and a 141dB max SPL, the SRX828S is an ideal solution for musicians, bands, and DJs, concert use, public speaking, or installations such as performance venues, corporate spaces, educational facilities or houses of worship.

Purposeful Design

Every detail in the SRX800 Series was purposefully designed and thought through with full consideration for its intended use. Ergonomically designed handles support an easy, non-fatiguing grip for streamlined handling. M10 suspension points, indexed feet, and pole/tripod mounts support a wide, flexible array of configurations.

Transducer Technology

JBL’s patented Differential Drive Technology ferrite drivers incorporate 3" voice coils with lower mass ferrite magnets for reduced weight, increased power handling, exceptionally low distortion and extended low frequency response. JBL’s 2432H is the only neodymium 3" voice coil compression driver in this class, delivering very high power levels and smooth, crystal clear sound.
