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.

What you get for that grand-and-a-half is a highly engineered loudspeaker that incorporates many of the patented Finite Element Analysis-based technologies that JL Audio has been introducing since 1997‚Äîsuch as its Dynamic Motor Analysis program for computer-optimizing driver design, its Vented Reinforcement Collar driver-mount system, its Floating Cone Attachment method of driver construction, and its Engineered Lead-Wire System for internal wiring. You also get a built-in, proprietary Class D amplifier (powered by a proprietary switch-mode power supply) said to be capable of 1200W RMS; a genuine two-way (high-pass and low-pass), built-in, active crossover using a fourth-order (24dB/octave, 80dB/decade) Linkwitz-Riley filter, equipped with variable gain, variable crossover-frequency, and variable phase controls, as well as a polarity (absolute-phase) switch; a ten-inch JL Audio woofer with dual spiders and a linear motor system engineered to provide equal force over the driver‚Äôs entire excursion range (with both positive and negative current flowing through the coils) at any applied power level up to the built-in amp‚Äôs peak; and a sealed box whose entire front panel is actually the steel mounting flange of the E-Sub‚Äôs driver assembly (the back plate of the driver is threaded and bolted to the thick rear wall of the enclosure). In sum, the e110 represents a lot of technology for the money. Read More:
