Powered Subwoofer with 12-inch Subwoofer, 1500 watts
Applying a series of our key technologies, E-Sub powered subwoofers deliver exceptional sound quality, power and value in a wide range of demanding applications
E-Sub drivers employ our exclusive DMA technology to optimize the drivers’ motor strength, ensuring linear behavior over a very long excursion range. Unlike typical steady-state modeling systems, DMA takes into account the dynamic shifts created by current flow and back EMF under real power conditions, with real program material. The payoff offered by DMA optimization is a driver that faithfully tracks its input signal, at all listening levels, leading to superior bass definition and dynamics.
The extreme mounting depth of the E-Sub driver is very deliberate. It permits wide gaps to exist between the three suspension elements (the rubber surround and the dual spiders), imparting exceptional mechanical stability over the driver’s full excursion range. This further improves linearity, reduces distortion and enhances long-term reliability. In a stroke of engineering elegance, the E-Sub’s steel front mounting flange forms the entire front baffle of the finished product, while the driver’s back-plate is threaded and bolted to the rear wall of its enclosure for support.
To power these innovative drivers, we engineered a completely new switching amplifier with a regulated, switching power supply, making its chassis more compact, lightweight and efficient, while still delivering ample, clean power to fully exercise the E-Sub driver’s performance envelope.
Conveniently controlled from the E-Sub cabinet’s top panel, the amplifier incorporates studio-grade signal processing to make adjustments a much more enjoyable experience than rear–mounted controls found on most powered subwoofers. An attractive cover hides and protects the controls during normal use.
The 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. Analog inputs are provided for unbalanced line-level signals or speaker level signals. Dedicated line outputs are included to make a bi-amped system arrangement with no additional hardware required. Useful in combating ground-related noise problems, a rear panel switch configures the line level inputs as grounded or isolated.
The E-Sub’s active crossover is a true two-way, 4th order Linkwitz-Riley design, with a low-pass filter feeding the subwoofer’s amplifier and a high-pass filtered signal exiting its line outputs. When the on-board crossover is defeated, as is typical in a home theater installation, the line outputs deliver a pass-through, buffered signal identical to its line inputs, easily permitting multiple E-Subs to be interconnected in a ‘daisy-chain’ arrangement. Switchable polarity and a fully variable phase control round out the signal processing section. All signal processing is performed in the analog domain, ensuring very low latency in critical applications.
Precision-built in JL Audio’s U.S. factory, all E-Sub are individually performance-verified and tested to deliver years of listening enjoyment in your home audio or home theater system.

Product of the Year

Editors’ Choice Award Winner
The Absolute Sound, 2004-2023 (e110 & e112)
Golden Ear Award 2015 – e110 & e112 – Robert Harley
“These subs are quick and agile, reproducing transient information with no smearing of leading-edge attacks or decays. As a result, the subs don’t dilute pace and rhythm, as many subs do. Both subs go low, play loudly, and do both at the same time without any sense of strain or compression of dynamic peaks. A stone-cold bargain, and an easy choice for a Golden Ear Award.”

“Despite ‘light on its feet’ agility, the e112 also delivers tremendous bottom-end authority. It’s this combination of finesse and impact that makes the e112 such a stand-out in a crowded field—and at an eminently affordable price.”

“At the end of the day, the E-Sub e112 is an output beast with fidelity to match. That’s worth the asking price in most any system. In fact, its performance makes the e112 the no-brainer buy of the year.”

Exceptional Value: Subwoofers
JL Audio E-Sub e112 subwoofer: Whenever I read do-it-yourselfers’ proclamations that they can build subwoofers of their own design that better, at lower cost, the models from JL Audio, I laugh. Those folks fail to recognize the value of such things as warranties and good resale values. But even setting aside these practical considerations, the E-Sub e112 ($1900-$2100, depending on finish) sounds superb, easily besting in overall sound quality what I’ve heard from 90% of the subwoofers out there. Despite its entry-level placement in JLA’s line of home models, this is one serious sub.
“Being a fiend for accuracy and precision meant the E112 and I got along very well. It was near impossible to make this thing sound bad. To be honest, I’m not sure if I ever did; as you crank up the volume it just gets louder and louder, yet it never loses composure.”
“JL Audio is renown for sound quality and the E112 is no exception, clearly adhering to the company ethos. Regardless of what I played, how high or low the volume, how challenging and complex the passage, dynamics and transient response were superb. The output was always nimble, never once being confused or overwhelmed by what I had chosen. I don’t lightly bestow the term “musical” on any subwoofer, but the E112 certainly fits my description of the word.”
