Introduction
EF30 Series Speakers
Congratulations on your purchase of EMP Tek speakers! Your speakers are the result
of many years of research and development.
is manual contains setup recommendations and specications for the EF30, EF30C
and EF30T speakers. It is highly 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, operate and maintain your
speakers for optimum performance and maximum enjoyment.

Features
At the heart of the EMP Tek EF30 Series speaker system is a berglass cone bass/mid-
range driver (speaker). e berglass cone resists exing better than typical speaker
cone materials, thereby providing highly articulate and accurate reproduction of the
audio signal. e stiness and lightweight characteristics of berglass, combined with
the driver’s large motor structure, give the drivers high excursion capability. is high
excursion capability prevents compression or distortion of the audio signal, which
leads to higher overall sound quality. e smaller drivers and tweeters in select EF30
speaker system are video shielded to cancel any stray magnetic elds which may cause
interference with video equipment such as CRT televisions.
A high quality so dome tweeter is used for high frequencies in the EF30 Series. Higher
power handling is achieved through the use of magnetic liquid cooling in the tweeter.
To protect the tweeter against being over driven, a Polyswitch (a DC current limiting
device) is incorporated in the crossover network. Each EF30 Series model features an
extensive crossover network. e use of these high quality crossover networks allows
each speaker to operate at its optimal performance. Steep acoustic crossover slopes
are used to integrate the drivers; the use of steep crossover slopes allow higher power
handling, minimizes driver interaction irregularities, and maximizes the ability of
each driver in their respective band of frequencies. Large 5-way binding posts ensure
a good, solid electrical connection to these crossover networks.
e EF Series cabinets are constructed of ¾-inch MDF because of its inert properties,
thereby preventing sound coloration due to cabinet diraction. e thickness of the
front baes also prevents excess acoustic radiation.

Break In Period
Allow several hours of listening time for your speakers to adequately break-in. During
this period, the driver suspensions will loosen, the result will be an increase in bass,
improved denition, and increased clarity and detail.
Care and Cleaning
To maintain the speaker’s high quality appearance, it is recommended you regularly
use a dry or slightly-damp so cloth to keep the exterior of your speakers free from
dust, lint or dirt. To clean dust from the grille, use a vacuum with a brush attachment
and gently brush the surface of the grille.

Attaching Speaker Wires
When using a banana jack to attach speaker wires to the binding post terminals, insert
the speaker wire into the banana jack. Next insert the banana jack into the binding
posts. When using a banana jack 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 counterclockwise 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
jack into the hole provided in the top of the terminal, and then continue to tighten the
nut until secure. Repeat for the other speaker wire(s) as necessary.
If not using a banana jack, 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.

In order to obtain the best possible sound from your speaker system, it is important to
determine where the speakers will sound best in your listening room. Sound 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 the 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 Le and Right Speakers
As a starting point, place your le and right EMP Tek EF30T tower speakers at least 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. Angling the speakers inward towards the listening position may give a more
spacious and realistic sound stage.
Center Channel Speaker
e EMP Tek EF30C Center Channel Speaker should be centered between both le
and right main speakers. Oen this positioning dictates placing the speaker either
directly above or below a television monitor. Since the EF30C is video shielded, the
center speaker may be placed in close proximity to a television without cause for
concern. e EF30C center channel speaker may be placed in a horizontal (lying down)
or vertical (standing) position.
Rear Surround Channel Speakers
e TK-5C 2-way Bookshelf Speakers may be placed either above, behind or to the sides
of the listening position. e listening position should be centered between the surround
speakers. For best performance you may want to experiment with angling the surround
speakers either towards or away from the listening position.
Subwoofer
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 close to a wall. Good results can usually be obtained by placing
a subwoofer along a wall 1-3 feet from a corner. 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 requirement. Dolby Digital EX and DTS ES add a center
rear speaker. Please consult your audio/video professional to determine which system is best for you and how
many speakers you will require.
