Introduction

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.

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.

Features

At the heart of the EMP Tek EF30 Series speaker system is a berglass cone bass/mid­range 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.
