1. Woofer  
4. Enclosure  
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.  
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.  
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.  
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.  
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.

Installation

or 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.

Placing the Studiophile AV 20  
5
he 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.  
T
1. The two monitors and the listener should  
align to form an equilateral triangle.  
2. Place the monitors so that the tweeters  
point directly towards your ears.
