Product description


Product Description

The TW-S7 USB powered speaker system incorporates cutting-edge technology to achieve 10W + 10W dynamic output of high-fidelity stereo sound using a direct digital connection and power supplied by the USB port of any personal computer.

From the Manufacturer

Designed to unmask the full potential of a personal computer to serve as a high-fidelity stereo digital audio transport, the TW-S7 USB Powered Speaker System delivers 10W+10W high-fidelity sound reproduction on USB power alone.


Simple USB-only Connection
Plug and Play
Direct USB digital audio connection minimizes addition of noise and distortion.
The TW-S7 Speaker System features plug-and-play capability with Windows and Macintosh personal computers over a single USB cable. The device installs automatically without the need for special drivers or software. Personal computers routinely transfer digital signals with no loss or corruption of data, but most PC speakers were not designed for high-quality digital to analog conversion. The TW-S7 speaker system receives a direct USB digital audio signal, amplifies it and converts it to high-resolution stereo sound with minimum added noise and distortion in order to reveal the full potential of a personal computer to deliver high-fidelity, audiophile sound.

Requires no electrical outlet; delivers 10W+10W output on USB bus power alone
Plug and Play
The SCDS charges a high volume capacitor during periods of low signal output to provide higher peak dynamic output.
The TW-S7 employs the revolutionary Super Charged Drive System(TM) (SCDS) to achieve 10W+10W peak dynamic output while consuming only 2.5W of power. SCDS operates similar to the drive system in a hybrid car, storing electrical charge during periods of low signal output and then releasing it during periods of higher signal output to achieve greater dynamic output on a continuous basis. Use of a newly developed high-efficiency digital amplifier and powerful speaker unit enable the TW-S7 to achieve remarkable output in comparison to other USB powered speaker systems.

Passive radiator provides deep bass reproduction
Plug and Play
Four major speaker configurations for bass reproduction: flat buffer, encapsulated, bass reflex and passive radiator.
Robust bass reproduction is essential for heartfelt musical enjoyment. The compact form factor of the TW-S7 conceals a 60mm diameter long stroke speaker unit and jointly co-developed passive radiator positioned along the same axis. This passive radiator employs bass resonance to provide acoustic bass reinforcement. Speaker systems employ one of four basic approaches to bass reproduction. A flat buffer speaker system requires a very large front panel. An ecapsulated system requires a very large box. A bass reflex system is constrained by the length of the port employed to generate vibration. A passive radiator, essentially a speaker with no driver magnet, provides an ideal solution for a compact speaker system.

Audio reproduction with sharp position and clear sound field
Plug and Play
The elliptical cabinet design eliminates unwanted reflection and diffraction of sound produced by conventional box-shaped cabinets, providing and ideal point sound source.
In a near field environment, the listening point is generally 50cm closer than in a standard living room environment. A sharp sound point is particularly important for PC speakers. The low diffraction, elliptical cabinet design employed by the TW-S7 Speaker System provides an ideal point source for faithful reproduction of the position and depth of each musical instrument. Sound orientation is further improved by employing a diffuser along the front axis to scatter high-range sounds in order to achieve reproduction of a sharp position and clear sound field.

Acoustically Ideal Elliptical Cabinet
Plug and Play
Box-shaped speakers require insulation to prevent the formation of standing waves, reducing the efficiency of space utilization. An elliptical cabinet has no flat surfaces alond which standing waves can form, making insulation unneccessary and allowing for near 100% effective utilization of space.
The elliptical cabinet design employed by the TW-S7 not only imparts greater strength than a box-shaped speaker of the same size while also eliminating standing waves that contribute to "box ring". The elliptical cabinet needs no insulation to absorb standing waves, reflected or diffracted sound, allowing the TW-S7 to achieve greater effective use of space.

High Quality Silicon Insulator Stands
Plug and Play
Silicone rubber insulators allow for fine tuning of speaker orientation.
High quality silicone insulator stands absorb vibration and all for fine-tuning of the angle of speaker orientation to provide a sharp listening point essential for a near-field listening environment.
