JL Audio E-Sub e112 Series Powered Subwoofer Black Ash Trade-In

Any great powered subwoofer system must start with an exceptional subwoofer driver. The E-Sub drivers offer impressive, low-distortion excursion envelopes capable of handling the most demanding program material, or the most delicate. To accomplish this, JL Audio's exclusive DMA technology is applied to shape, control and stabilize the drivers' motor strength, ensuring linear behavior over a very long excursion range. Unlike typical steady-state modeling systems, our approach 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 more faithfully tracks its input signal at all listening levels, leading to superior bass definition and dynamics.
