C-TECH SPK-20 Speaker 6W USB Black

The C-TECH SPK-20 Speaker 6W USB Black is a compact and reliable stereo speaker system designed to enhance your everyday desktop audio experience. Built with an MDF material cabinet, this speaker effectively dampens acoustic vibrations to deliver a more natural and balanced sound compared to standard plastic alternatives. With a total power output of 6W RMS, a frequency range of 100 Hz to 20 kHz, and an impedance of 4 ohms, it provides clear audio for music, movies, videos, and general computing tasks. Power is supplied conveniently via a standard 5V USB port, eliminating the need for an external wall adapter, while dual 3.5mm jack connectors handle the audio signal transmission for straightforward setup.

Advantages

One of the primary benefits of the C-TECH SPK-20 speaker is its solid MDF construction, which significantly improves acoustic performance by reducing unwanted vibrations and distortion. The inclusion of integrated ports directly on the speaker body, including a headphone output and a microphone input, offers exceptional convenience for connecting headsets without reaching behind the computer. Furthermore, the USB-powered design ensures energy efficiency and reduces cable clutter on your desk, making it a practical addition to any workspace.

Suitable for

• Enhancing desktop audio for music playback and casual listening
