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. Inside each E-Sub™, a state-of-the-art, long excursion JL Audio driver combines with a highly efficient, proprietary switching amplifier to deliver astonishing performance from a very compact subwoofer cabinet.
“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.” – Jim Wilson, Home Theater Shack
The E-Sub™ driver is an unconventional design, requiring very specific production fixtures and procedures. As one of our highest technology subwoofer drivers, it is built by the same team that assembles our flagship W7-HT drivers, and is tested to the same quality standards. Final assembly of every E-Sub™ takes place in our Miramar, Florida factory, where skilled technicians bring together the driver, enclosure, and electronics package. A full acoustical and electrical test takes place at the end of the production line, to verify the performance of each finished subwoofer.
