Studiophile LX4-2.1 Features

1.Woofer

- the woofer unit is 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. Tweeter

- by employing a specially developed 1-inch mylar dome with

magnetic shielding, the tweeter 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

- 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’s enclosure has an

important role. In order to provide more stable performance, the LX4’s
enclosure 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 active equalization and crossover

networks, as well as the power amplifiers for the LX4-2.1 are specially designed
for the specific woofer, tweeter and sub-woofer chosen. 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 drive the Sub-Woofer,
plus Left, Right, and Surround speakers separately, in a high-end
multiple-amplifier structure. The power delivered to the sub-woofer driver is
60W, while 27W is delivered to the Left and Right Speakers, and to each
Surround speaker, when LX4-3.0 is installed (see the next feature).

6. Expandable System

- LX4-2.1 is designed with the option to add the

LX4-3.0 package, and upgrade the LX4 into 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.
