ESD1.12 · Overview
Introduction
The ESD1.12 is a very compact passive, high output subwoofer. The ESD1.12 is a passive version of the active EX1.2,
12" subwoofer and features the same high quality neodymium driver.
This subwoofer's low prole and size makes it ideal for discreet applications.
With a power handling of 600 watts, the ESD1.12 is capable of delivering tight, fast, controlled bass response at high
output levels from a compact cabinet.
The ESD1.12 woofer is protected by a reverse thermal-circuit breaker (autoreset) and features a professional Baltic Birch
construction with a wear resistant polymer coating and a specially designed handle for simplied handling
and carrying. The ESD1.12 is also available in any RAL colour (white RAL9003 on stock).
Application
Specically designed as a passive subwoofer to accompany
and compliment the ESD5/6 as a true full range system
• For xed installation
• Bars-small entertainment projects
• Small footprint and dimensions allow placement under
seating and xtures
ESD1.12 - part number KVV 987 225
Connection
The ESD1.12 features both Speakon (NL4) connectors and a terminal block. The connectors are interconnected in
parallel to allow the "daisy chaining" of additional ESD1.12's.
