ESD5 · Overview
Introduction
The ESD5 is a very high quality 2-way full-range compact low prole passive loudspeaker with performance that
dees its size. Delivering exceptional clarity for speech and program reproduction, the ESD5 is perfect for discreet
installations and audio visual presentations where sound quality is paramount, but aesthetic dimensions are of equal
importance. The ESD5's high impedance capability means that up to sixteen units can be run from a single suitable
quality stereo amplier, to provide a high delity background program throughout a venue.
A built-in switchable voice eq circuit is included.
Application
Specically designed as a super- discreet passive
loudspeaker for reproduction of recorded music and speech
• Suitable in xed installations as a full range speaker or as
a system with accompanying subwoofers
• Excellent peripheral reinforcement for main KV2 systems
• Fill-in speaker
• Monitoring
• Ceiling or under balcony mounting
ESD5 - part number KVV 987 340
The Ultimate Compact Passive System
Connection
The ESD5 features both Speakon (NL4) connectors and a terminal block. The connectors are interconnected in parallel
to allow the "daisy chaining" of additional ESD5's.

ESD5 · Installation · Drawings
Installation
The ESD5 is supplied with a single "ESD5 Wall Bracket", 2 locking screws with spacers and one 3 mm Allen key. Each
ESD5 is quipped with two oval mounting apertures designed for easy vertical or horizontal attachment to the ESD5
Wall Bracket.
To enable xing to a ceiling or alternatively to the wall, measure out the center point of the ESD5 Wall bracket. There
are two extra holes on the Wall Bracket, designed to accept locking screws - this side belongs on the rear side of the
ESD5 cabinet.
Fix the Wall bracket using one center countersunk screw. Rotate the Wall bracket around the central screw and set the
correct angle of the bracket.
Fix the Wall Bracket using the remaining four countersunk screws. Position the ESD5 on to the Wall Bracket‘s pin heads
and x it sliding the cabinet down. When mounting the ESD5 on the ceiling, slide the cabinet backward and x/secure
it using two locking screws and tighten using the supplied Allen key.

ESD25 · Overview
Introduction
The ESD25 is a very high quality, 2-way full-range compact low prole passive loudspeaker with enhanced lower bass
extension. Its opposing driver design assists with pattern control of the low mid frequencies, reducing reections in
reverberant spaces and improving intelligibility. Delivering exceptional clarity for speech and program reproduction,
the ESD25 is ideal for under balcony or front stage ll applications in theaters and performing arts spaces where
transparent supplementation of the main system is required. As with the already widely acclaimed ESD5, the ESD25
is shaped to t discreetly into these applications and comes with its own integral bracket for quick installation.
A built-in switchable voice eq circuit is included.
