Introduction

Congratulations on your purchase of an EMP Tek ECA4 or ECA44 compact
theater speaker! Your speaker is the result of many years of research and develop­ment dedicated to producing powerful, high-quality home audio systems.

is manual contains setup recommendations and specications for the ECA4
and ECA44 compact theater speakers. It is recommended you thoroughly
read through the material contained in this manual before connecting your
speakers. is will ensure you have an understanding of how to properly setup
and operate your speakers for optimum performance.

Break In Period

Allow several hours of listening time to adequately allow the ECA4 and ECA44
speakers to break-in. During this rst 18-24 hour listening period, the driver’s
suspensions will loosen, resulting in an increase in low frequency response,
improved denition, and increased clarity and detail.

Care and Cleaning

To maintain the speaker’s high quality appearance, it is recommended to
regularly use a dry or slightly-damp so cloth to keep the exterior free from dust
or dirt. To clean dust from the grille, use a vacuum with a brush attachment.

Features

At the heart of the ECA4 and ECA44 compact theater loudspeakers are pro­prietary aluminum cone woofers and midrange drivers. e special material
combines stiness, low mass and self-damping properties in a manner that
allows virtually uncolored presentation of program material.

A powerful magnet, extended voice coil and bumped back plate give the bass/
midrange drivers high excursion capability. is ensures accurate dynamic
reproduction. e driver is shielded by using a steel cup and an additional
magnet to cancel any stray magnetic eld that may cause interference with
video equipment such as CRT type televisions.

For high frequencies, a premium quality silk dome tweeter is used. This
tweeter uses liquid cooling to allow greater power handling and is also
magnetica lly shielded.

Steep acoustic slope crossovers are used to integrate drivers. e use of steep
crossover slopes allows high power handling, minimizes driver interaction
anomalies, and maximizes the clarity with which each driver is able to produce
its respective frequency band. A polyswitch, or current limiting device, is used
in the crossover to prevent damage to the tweeter if over-driven. is device
is engineered to work 900% faster than a fuse.

Constructed of cast aluminum, the cabinets also have a narrow prole to
minimize cabinet diraction. e speakers practically disappear leaving
only a deep, wide sound stage with pinpoint imaging. High quality binding
posts ensure a good electrical contact. Sophisticated computer modeling
and measurement techniques are used extensively in the EMP loudspeaker
design process.
