E-Sub e112-ASH

With a number of our key technologies, E-Sub subwoofers offer exceptional sound quality, performance and value in a variety of demanding applications. E-Sub drivers use our exclusive DMA technology to optimize the driver's engine power and ensure linear behavior over a very long distance. Unlike typical stationary modeling systems, DMA considers the dynamic shifts generated by current flow and back EMF under real power conditions with real program material. The output 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 installation depth of the E-Sub driver is very conscious. It allows large gaps between the three suspension elements (rubber surround and dual spider), providing exceptional mechanical stability over the full range of the driver. This further improves linearity, reduces distortion and increases long-term reliability. Engineered elegance is provided by the E-Sub steel front mounting flange and the entire front panel of the finished product, in addition, the rear wall of the driver is threaded and bolted to the rear wall of the housing for support. To provide these innovative drivers, we have developed a completely new switching amplifier with a regulated switching power supply that makes its chassis more compact, lighter and more efficient while still providing sufficient, clean performance to fully perform the performance environment of the E-Sub-Driver.
