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.
