ESD1.10

ESD1.10 – part number KVV 987 391
Overview
SUBWOOFER 500Watts

Application

Specifically designed as a passive subwoofer to accompany and compliment the ESD Cube systems, or as a standalone compact low-frequency solution for space- limited applications.

• Fixed installations
• Bars-small entertainment projects and peripheral sound
• Museums or Theme park projects
• Small footprint and dimensions allow placement under seating and fixtures

Introduction

The ESD1.10 is a compact passive 10″ subwoofer featuring a high-quality neodymium transducer. The smallest subwoofer within the KV2 range, it has been designed to compliment the ESD Cube Ultra compact Passive loudspeaker, creating a full range system solution when partnered with the Cube and ESP1000 amplifier. With power handling of 500 watts the ESD1.10 is capable of delivering tight, fast, and controlled bass response, at high output levels from a very compact cabinet and is ideal for any discreet low-frequency applications alongside other KV2 Audio products.
Connection
The ESD1.10 features both Speakon (NL4) connectors and a terminal block. The connectors are interconnected in parallel to allow the “daisy chaining” of additional ESD1.10s.

Example of connection: ESD1.10 BriDgED output (8Ω)
