The JL Audio E-Sub powered subwoofers feature a new switching amplifier with a compact switching power supply. This design allows us to keep the E-Sub’s dimensions compact while delivering what JL says is ample clean power that will fully exercise the drivers’ excursion ranges. There are four versions that range from 1,200 to 1,500 watts and list from $1,700 to $2,100.
The E-Sub’s 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. A true, two-way onboard crossover with high-pass line outputs allows the E-Sub to integrate seamlessly with two-channel systems, and high-level inputs even make it possible to add an E-Sub to systems lacking line outputs. Polarity and variable phase controls make it possible to precisely blend the E-Sub’s output with that of your main speakers.
