JL-Audio Subwoofer E-Sub e 112

With a number of our key technologies, E-Sub subwoofers offer exceptional sound quality, performance and value in a wide range of demanding applications. E-Sub drivers use our exclusive DMA technology to optimize the driver's motor power and ensure linear performance over a very long distance. Unlike typical stationary modeling systems, DMA takes into account the dynamic displacements generated by the current flow and the counter-EMF under real performance conditions with real program material. The output offered by DMA Optimization is a driver that faithfully tracks its input signal at all listening levels and leads to superior bass definition and dynamics. The extreme installation depth of the E-Sub driver is very conscious. It allows large gaps between the three suspension elements (rubber surround and dual spider) that provide exceptional mechanical stability over the full range of the driver. This further improves linearity, reduces distortion and increases long-term reliability. Technical elegance is provided by the E-Sub steel front mounting flange and the entire front panel of the finished product, in addition, the rear panel of the driver is threaded and screwed to the rear panel of the housing for support. To power these innovative drivers, we've developed a completely new switching amplifier with a regulated switching power supply that makes its chassis more compact, lighter and more efficient while still delivering sufficient clean power to fully power the E-Sub driver's power environment.
