KV2 Audio ES1.8 18" High-Output Active-Driven Subwoofer
The KV2 Audio ES1.8 is a high-output 18-inch subwoofer designed as part of the KV2 ES Series sound reinforcement system. Its horn-reflex-loaded cabinet delivers tight, authoritative low-frequency performance with strong attack and definition, making it ideal for demanding live sound and venue applications.
Please note: the ES1.8 is not a self-powered subwoofer. It is designed to be driven by the KV2 EPAK2500 or EPAK2500R amplifier/control unit, which provides the required amplification and system processing.
