The E-Sub powered subwoofers apply a series of our key technologies to deliver exceptional sound quality, power and value in a wide range of demanding applications.Combining a state-of-the-art, DMA-optimized long excursion driver with a highly efficient, proprietary switching amplifier, E-Subs deliver a level of performance that belies their compact dimensions and cements their value.

The E-Sub subwoofer driver features a radical, deep architecture designed to create a highly linear, mechanical action and a motor design with enough linear excursion to handle the most challenging program material.

A totally new switching amplifier was engineered for the E-Subs, with a compact and efficient switching power supply. This design allows us to keep the E-Sub's dimensions compact while delivering ample clean power that will fully exercise the drivers' excursion ranges.

The E-Sub's feature set has been designed to allow the use of E-Subs in a wide range of applications, from full home theater systems to dedicated two-channel music systems, to desktop audio workstations. A true, two-way onboard crossover with high-pass line outputs allows the E-Sub to integrate seamlessly with two-channel systems, and high-level inputs even make it possible to add an E-Sub to systems lacking line outputs. Polarity and variable phase controls make it possible to precisely blend the E-Sub's output with that of your main speakers.

Every E-Sub is precision-built in JL Audio's U.S. factory and individually performance-verified and tested to deliver years of listening enjoyment in your home audio or home theater system.
