Introduction
ECA44 and ECA4 Compact eater Speakers
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 develop-
ment 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 pro-
prietary 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
magnetically 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.

To extract the best possible sound from your speaker system, it is important to
determine where the speakers will sound best in your listening room. Room
reections from the oor, ceiling and side walls inuence the balance, imaging
and overall sonic quality at the listening position. Experiment with speaker
placement to determine which location oers the best overall sound. As a
general guide, use the room layout diagram and the following descriptions
when setting up a home theater system. Some speakers shown in the diagram
may not always be applicable to your individual system.

Front Main Speakers
As a suggested starting point for the front le and right main speakers, try to place
your speakers about 15 inches from the wall and 7 feet apart from each other. e
distance from the listening position to each speaker should be close to the distance
that separates the two main speakers (i.e. triangle). e EMP compact theater speakers
can also be hung on a wall or placed in bookshelves to better match your décor. If this
is how your installation will proceed, keep in mind the spacing comments above for
best performance. Also, slightly angling the speakers inward towards the listening
position may give a more spacious and realistic sound stage.
Center Channel Speaker
For optimal performance in surround sound applications, the center channel speaker
should be placed in the center between both le and right main speakers. Oen this
positioning dictates placing the center channel speaker either directly above or below
a television or monitor. Since both the ECA4 and ECA44 compact theater speakers are
video shielded, the center speaker may be placed in close proximity to virtually any
television without cause for concern. Also, the ECA44 compact theater speaker may
be placed in either a horizontal (lying down) or vertical (standing) position.
Surround Channel Speakers
e surround channel speakers should be placed slightly above and behind, or to the
sides of, the listening position. e optimal listening position is usually centered between
the surround channel speakers. For best performance, you may want to experiment with
angling the surround speakers towards or away from the listening position.
Subwoofer
Placement of the subwoofer will largely determine the quality, quantity, and extension
of the bass frequencies within your listening room. Bass frequencies are reinforced
by close room boundaries. Placing the subwoofer nearer to a corner will make the
subwoofer sound louder and boost the very lowest frequencies. Placing the subwoofer
away from a corner or walls will provide the least reinforcement, making the bass
sound subjectively thinner than if the subwoofer were closer to a wall or corner. A
good starting point for subwoofer placement would be to place the subwoofer along a
wall 1-3 feet from the corner. You may want to experiment with subwoofer placement
and the sub-amplier controls to achieve the proper bass balance.
NOTE: ere are several dierent surround formats available. Dolby Pro-Logic, Pro-Logic II, Dolby Digital
and DTS generally have a 5-speaker plus subwoofer setup. Dolby Digital EX and DTS ES add an additional
center rear speaker. Some newer receivers also oer the use of 7 or more eects channels. Please consult your
audio/video professional to determine which system is best for you and how many speakers you will require.

When using a banana plug to attach speaker wires to the binding post
terminals, remove the black and red plastic protective inserts from the
terminals. To do this, loosen the binding nut from the terminal by turning the
nut counter-clockwise until the nut is completely removed from the terminal.
Remove the plastic inserts by pulling them straight out, then replace the nut to
the terminal and turn clockwise. Insert the banana plug into the hole provided
in the top of the terminal, and then continue to tighten the nut until secure.
Some banana plugs may be able to t into the terminal’s top hole aer the nut
is secure. Repeat for the other speaker wire(s) as necessary.
If not using a banana plug, simply loosen the binding nut to allow the hole
in the side of the terminal to become exposed. Strip ¼-inch of the insulation
from the end of the speaker wire and insert the exposed wire end into the
now exposed hole in the side of the terminal. Tighten the binding nut by
turning the nut clockwise until the speaker wire is secured. Repeat for the
other speaker wire(s) as necessary.
