Introduction
Thank you for choosing the Studiophile Series LX4-2.1 / 5.1 studio nearfield
monitor speakers. M-Audio is well known for digital audio interface technology,
digital converters, audio preamps and mixers. Now, born from extensive
research and development, the Studiophile LX4-2.1 System and 5.1 Expander is
changing the concept of studio reference monitoring in 2.1 / 5.1 systems.
The LX4-2.1 System is designed with the option to add the LX4-5.1 Expander
package, thereby upgrading to the LX4 Surround System, a 5.1 system for music
production or playback of 5.1 music and sound tracks.This feature makes the
LX4 system extremely flexible, fitting into all modern digital music production
and playback applications.
The LX4 Surround System was designed to overcome the size limitations of
conventional studio reference monitors within the digital audio environment.
The compact system delivers wide-range frequency response by employing two
extraordinary drivers,both of which are magnetically shielded for desktop music
production, and a unique crossover and equalization technology, licensed by
M-Audio.The LX4-2.1’s Subwoofer provides extended low frequency down to
40Hz, making it possible for the LX4 Surround System to use much smaller
Satellite Speakers and offer both ultimate convenience for desktop production
and highly accurate 40 to 20Khz frequency response range.
Designed and tested by veteran audio engineers to meet your needs in the
studio monitoring environment, the LX4 Surround System’s goal is focused on
delivering pure, original sound without any additional coloration. The LX4
Satellite monitors are self-powered from amplifiers contained in the Subwoofer
enclosure, which directly accepts a line level signal from a variety of sources.
For pro engineers at commercial studios to home studio owners, the Studiophile
LX4 Surround System sets a new affordable standard in studio monitoring.

Studiophile LX4 Surround System Features
1. Satellite Woofer - the Satellite Speaker’s woofer units are 4 inches in
diameter with a magnetically shielded mineral-filled polypropylene cone, high-
temperature voice coil and damped closed cell foam surround. It is designed to
deliver balanced mid- and low-frequency response. Polypropylene is used to
react against the input signals accurately, and to deliver even minimal input
precisely while minimizing distortion.
2. Satellite Tweeter - by employing a specially developed 1-inch mylar
dome with magnetic shielding, the  Satellite Speaker’s tweeters can deliver
distortion-free original sound and offer extremely natural response. It minimizes
reaction time by using a uniquely shaped mylar dome for excellent delivery, and
also minimizes resonance by adapting a unique internal damping technology.
3. Sub-Woofer (LX4-2.1 System) - the Sub-woofer unit is 8 inches in
diameter with a specially developed curved profile pulp cone, high-temperature
voice coil and damped closed cell foam surround. It is designed to deliver
subwoofer sound pressure at very high efficiency with extremely low distortion.
4. Enclosure - just as other components do, the LX4 Surround System
enclosures have an important role to play. In order to provide more stable
performance, these enclosures employs a special high-density MDF and unique
interior reinforcement designed to absorb vibration and impact generated
under extreme conditions.
5. Network & Power Amplifiers - the LX4 Surround System’s active
equalization and crossover networks, as well as the power amplifiers housed in
the 2.1 Sub-woofer are specially designed for the specific carefully-chosen
woofer, tweeter and sub-woofer drivens.The network properly distributes low,
mid, and high frequencies to the components in order to reduce distortion and
loss of signal, thereby achieving a naturally balanced sound.
In order to generate powerful, ultra-crisp sound, there are six separate power
amplifiers inside the LX4-2.1 Subwoofer module. These separately drive the
Sub-Woofer, Left, Right, Center and Surround Left and Right speakers in a
high-end multiple-amplifier structure. The power delivered to the sub-woofer
driver is 60W, while 27W each is delivered to the Satellite Speakers.
6. Expandable System - LX4-2.1System is designed with the option to add the
LX4-5.1 Expander package,thereby upgrading to a 5.1 system for music production
of 5.1 music and sound tracks. The feature makes the LX4 system extremely
flexible, able to fit all modern digital music production and playback applications.
