The ES10i powered subwoofer has its own source of amplification (as opposed to passive, non-amplified subwoofers which require an additional power amplifier). This subwoofer can add considerable low-frequency, deep bass performance to your home theatre or audio system.
Variable crossover, adjustable phase control and auto on / off are also used for convenience and easy integration with other speakers. Audio can be supplied to the subwoofer by either interconnect (processor / line level) or speaker wire (high level). The 10” poly-matrix cone woofer enhances bass definition and accuracy. A built-in limiter protects the ES10i from being driven and bottoming out.
