Studiophile AV 20 Features

1. Woofer
The woofer unit is 2” in diameter and is
magnetically shielded to protect your
computer video monitor from interference. It
includes a high-temperature voice coil and 2”
polypropylene treated paper cone. The woofer
delivers balanced mid- and low-frequency
response.
2. Tweeter
By employing a specially developed 1” Mylar
diaphragm with protective magnetic shielding,
the tweeter can deliver an extremely natural
response. It minimizes resonance by adapting a
unique internal damping technology.
3. Bass Reflex Port
The hole in the rear panel is a bass reflex port.
It is designed to discharge very low frequency
signals and enhance the overall bass response.
4. Enclosure
Along with the other components, the
Studiophile AV 20’s enclosure plays an
important role. In order to provide more stable
performance, we used a special medium-
density fiberboard (MDF) and unique interior
reinforcement designed to absorb vibration and
impact generated under extreme conditions.
Additionally, our innovative speaker monitor
cabinet includes carefully placed acoustic
material that makes the Studiophile AV 20
sound much bigger than it is—resulting in a
smooth, natural bass response.
5. Network & Power
Amplifiers
The power amplifiers and crossover network, for
the Studiophile AV 20 are specially designed for
this woofer and tweeter. The network distributes
low-, mid-, and high-frequency audio signals
to the proper components in order to minimize
distortion and to achieve a balanced sound.

Installation
4
For optimal performance of the Studiophile AV 20, please read the following directions carefully before installation.
Precautions
Connections: Your Studiophile AV 20 monitors have a single pair of RCA inputs for use with a
multitude of devices. Use the provided cable to connect your soundcard’s 1/8” line output to the
RCA inputs on your left speaker’s back panel. If your soundcard or alternative audio playback
device is equipped with a different type of output connector (e.g. RCA outputs on M-Audio
Delta Audiophile 24/96), then you will need to purchase an adapter or a cable with male RCA
connectors on one end, and the connector that matches your playback device on the other end.
Correct Power Operation: Since the Studiophile AV 20 contains amplifiers, it must be
connected to a power outlet using the detachable AC cable that is provided. Before connecting
power, please make sure that the On/Off switch on the back of the Studiophile AV 20 is set to the
off position.
WARNING! - Use of improper voltage may result in hazardous conditions and/or damage to
speaker components not covered by speaker warranty. Please make sure the voltage is set
appropriately by checking the the position of the red “AC Select” switch on the back before
powering on your speakers.
Acoustic/Traction Pads
In order to minimize vibrations and maximize physical stability, we
recommend you use the provided acoustic/traction pads on the
bottoms of the Studiophile AV 20 monitors.
Speaker Wire Connections 1
Use the transparent tinned bare wire cable included in the Studiophile
AV 20 package to connect the Left and Right speakers via the red
/black spring-clip terminals on the back of each speaker.
Connecting to a Computer Sound Card
or Other Audio Output Device 2
Before connecting the Studiophile AV 20 monitors, make sure the
power from the computer or other output device has been turned off
and the Studiophile AV 20 system is also turned off.
Connect the RCA input jacks to the corresponding output connectors
of a computer sound card, portable music player, etc.

Placing the Studiophile AV 20
5
The way you position your speakers can greatly affect the way they sound. It is important to place your new reference monitors so that their tweeters are pointed directly towards your
ears. Ordinary monitor speakers usually need to be elevated to ensure that their tweeters are level
with the listener’s ears. However, thanks to AV 20’s unique curved front panel design, the ideal
angle between tweeters and ears is achieved by simply placing them directly on the surface of your
desk.
1. The two monitors and the listener should
align to form an equilateral triangle.
Left Monitor Right Monito

2. Place the monitors so that the tweeters
point directly towards your ears.
