Introduction
E10s Subwoofer
Congratulations on your purchase of an EMP Tek E10s Powered Subwoofer! Your
subwoofer is the result of many years of research and development dedicated to
producing powerful, accurate bass in home audio systems. is manual contains
operating procedures and specications. We recommend you thoroughly read
through the material contained in this manual before connecting your subwoofer.
is will ensure you have an understanding of how to setup and operate your
subwoofer for optimum performance.
Break In Period
Allow 10-15 hours of listening time to adequately break-in the E10s Subwoofer.
During the break-in period, the driver suspension will loosen. e result of break-in
will be an increase in low frequency response, improved denition, and increased
clarity and detail.
Care and Cleaning
To maintain speaker appearance, we recommend an occasional application of a
general purpose no-wax surface and furniture cleaner. is may also be used to
gently clean the aluminum cone surface. To clean dust from the grille cloth, use a
vacuum with a brush attachment.
Features
A powered subwoofer is a must-have component for any home theater or audio
system. e performance of your subwoofer can greatly aect the overall
performance of your system. Without a powered subwoofer, the deep bass on your
music CDs and special eects on DVDs may not be heard and/or felt. ink of
a subwoofer as a vital component that adds excitement to your theater or music
experience. e powered subwoofer has its own source of amplication (as opposed
to passive, non-amplied subwoofers which require an additional power amplier).
Subwoofers can add considerable low-frequency, deep bass performance to any
home theater or audio system.
At the heart of the EMP Tek E10s powered subwoofer is an aluminum cone driver.
e driver material produces enhanced bass denition and accuracy. A powerful
magnet, enhanced suspension and heavy duty voice coil give the driver elevated
performance allowing high output capability and accurate dynamic reproduction.
e E10s powered subwoofer incorporates a discrete class A/B analog power supply
amplier ensuring low distortion, high current output and proven reliability. Variable
crossover, adjustable phase control and auto on/o are also used for convenience and
easy integration with other speakers. Audio can be supplied to the subwoofer by
either interconnect (processor/line level) or speaker wire (high level).
Cabinets are constructed from medium density berboard because of its inert
properties. e thickness of the front baes also prevents excess acoustic radiation.
Large binding posts ensure a good electrical contact. Sophisticated computer
modeling and measurement techniques are used extensively in the EMP Tek
subwoofer design process.
Setup Suggestions
Placement of the subwoofer will largely determine quality, quantity and extension of
the bass frequencies within your listening room. Bass frequencies are reinforced by
close room boundaries. Placing the subwoofer in a corner will make the subwoofer
sound louder and boost the very lowest frequencies.
Placing the subwoofer away from walls will provide the least reinforcement, making
the bass sound subjectively thinner than if the woofer were closer to a wall. Good
results can usually be obtained by placing a subwoofer along a wall 1-3 feet from a
corner. Experiment with placement of the subwoofer and the sub-amplier controls
to achieve the proper bass balance.
It is important the signal being sent to the subwoofer be a non-boosted or “at” signal.
To be sure of this, check the settings on your receiver or processor to determine any
“bass boost”, “super bass” or “loudness” is set to O. In most cases for home theater
setting a receiver or processor will determine the crossover frequency through bass
management settings. In this conguration, connect the receiver or processor to the
LFE Line Level Input. Your subwoofer can now reproduce the bass frequencies the
way they were originally recorded. Use the subwoofer level control and the individual
bass management control within the receiver or processor to adjust the subwoofers
volume if necessary. Once set, the volume controls should not need to be altered as
the subwoofer’s volume will coincide with the master volume control of your receiver
or processor.
Setup Suggestions (continued)
1. Volume Control: e volume control should be at the
minimum setting (all the way counter clockwise) before
plugging the subwoofer into a 120V AC wall socket.
2. Crossover Frequency Control: e variable crossover
frequency control allows you to set the crossover point
of the subwoofer anywhere from 50-150 Hz. is control
is only active with use of the le and right line level
inputs (#5) and speaker level inputs (#6). If using these
inputs experiment with setting the crossover frequency
control at highest setting initially. Increasing the
crossover frequency will allow more mid-bass output
from the subwoofer. Decreasing the frequency will
cut more mid-bass output from the subwoofer.
3. Phase Control: is control changes the phase of the
subwoofer. Changing the phase will change the way the
subwoofer and main speakers interact with each other at
the crossover frequency. Varying the phase position may
result in more or less mid-bass depending on the phasing
between the main speakers and the subwoofer. Generally,
the phase is le at the 0° position.
4. LFE Line Level Input: Typically this will be the line level
input used to connect to most receivers or processors.
e LFE input will bypass the subwoofer’s crossover
control. is input should be used when the input signal
is coming from a receiver or processor where the bass
management is controlled by the receiver or processor.
5. L/R Line Level Input: If a full-range signal is being sent
from the receiver or processor then these inputs should
be used. In this conguration, the crossover frequency
(#2) is active.
6. High Level Input: ese binding post terminal
connectors are for the amplier/speaker level input from an amplier or receiver.
Usually, the LFE line level input (#4) will be used. Important! Use either the Line Input
or the High Level Input. DO NOT use them both simultaneously.
7. High Level/Speaker Output: is is a 100 Hz high-passed output for your satellite/main
speakers. e crossover limits the low frequencies (below 100 Hz) from going to your
satellite/main speakers. is crossover is active only when using the High Level Input
terminals. Connect your main speakers (observing the proper polarity) to the terminals
labeled “High Level Out”.

Replace fuse (if fuse is not readily
accessible, consult your autho-
rized EMP Tek dealer).

L/R line level input is con-
nected instead of the LFE line

use the LFE line level input. (See
amplier controls and setup on
previous page.)
