ESD8 · Introduction
Introduction
The ESD8 is a compact passive 2-way, high output full-range loudspeaker incorporating an 8" trans-coil woofer
and a 1" compression driver coupled to a wide dispersion horn. Presented conservatively in a unique angled low-prole
Baltic birch enclosure and designed to present exceptional speech and music denition, the ESD8 provides a smooth hi
delity response and delivers a natural sound quality and level that is superior to many larger competing products.
Ideal as a main system speaker or as an in-ll for larger systems, the exible ESD8 can be applied quickly and eciently
on podiums, stands or suspended.

Installation
Installations should be carried out using KV2 Audio's horizontal or vertical U brackets. They are mounted vertically
using M10 points located on the side of the cabinet or in the top handle and bottom M10 plate (supplied with

The ESD8 also features a 35 mm speaker pole mount adapter housed at the bottom of the cabinet for use with
conventional speaker stands and poles.
