Manufacturer Description
The ES 1.8 is a high-output, reflex horn loaded, single eighteen inch subwoofer designed as a part of the ES Series sound reinforcement system. It provides tight, up front, low frequency extension with authority, attack and definition. Designed to be used in pairs, or with an ES 1.5, the ES 1.8 can achieve high output levels consistently and safely. Alongside the ES 1.0 and EPAK 2500/R, ES 1.8 offers a very firm foundation on which to build a powerful ES system.
