The ES 1.8 is a high-output, front-loaded single eighteen-inch bass module designed as a part of an ES Series sound reinforcement speaker system. It provides tight, up-front, low frequency reinforcement via a front-loaded design with large-format porting that, provides improved attack and definition. By optimizing the ideal operating band pass of each system component; the ES 1.8 can achieve high output levels consistently and safely.

• High-output, single 18-inch, Bass Module
• 129 dB of output (per unit) — 134 dB (when using 2 units)
• Acoustic loading via large-format low-distortion reflex port
• Eighteen-inch Low Frequency driver with 4.00” (100mm) polymide, high temperature voice coil assembly and carbon fiber reinforced cone assembly
• Professional, exterior grade Baltic birch construction with highly resistant polymer coating
• Proprietary corner handle design for simplified handling and carrying
• Acetal copolymer high impact, low friction feet are asymmetrically located on two sides allowing vertical or horizontal system set up, lock-in and easy cabinet movement
• Six internal corner braces with twelve M10 suspension points.

Power for the system is provided by the EPAK 2500 Amplifier/Processor ensuring fast, easy set up and complete control. Together with the ES 1.0 and EPAK 2500, they deliver the highest dynamic range of any system currently available providing new levels of clarity, depth and resolution.

Italian-crafted LF transducer.
KV2 Audio’s transducer development and manufacturing partner, 18 Sound in Cavriago, Italy, manufactures the woofer for the ES 1.8. The device is the result of their state-of-the-art R&D facility and advanced production capabilities. The transducer features a double silicone spider, polymide voice coil assembly that undergoes multiple baking and curing processes as well as an advanced magnetic structure with advanced cooling system.

Easy to move around. Easy to set up and tear down.
The ES 1.8 is a very compact, lightweight enclosure featuring a number of ergonomically designed parts that make it an easy speaker to set up and use. KV2 designed and tooled a new very compact “corner handle” that fits snugly into any 90 degree corner. This provides critical pick-up and handle -locations previously unavailable. There are eight corner handles that make it easy to pick up and reposition the ES 1.8 in a natural, instinctive manner.

Even the ES 1.8’s “feet” are a new design.
One longstanding problem with standard cabinets is their rubber feet, which prevent you from moving or sliding the enclosure easily into a desired position. They’re also easily damaged since they protrude from the box. KV2 has addressed this issue by molding our own feet using acetal copolymer material. This material has two very essential properties that make it ideal for use in this application, high density and a very low coefficient of friction. The enclosure has eight of these feet placed on two sides of the cabinet. Their asymmetrical placement allows easy setup, alignment and construction of a number of different system configurations.

Fly it to the moon (with really long cables).
There are six industrial grade, internal braces placed at each corner. Each brace is held in place by four M6 and two M10 bolts providing a wide range of installation and suspension flexibility
