Stereo portable speaker C-TECH Impressio Qubis Black
The C-TECH Impressio Qubis Black is a stereo portable speaker designed for versatile audio playback in home, outdoor and event settings. With an RMS rated power of 80 W and a frequency response from 15 to 18,000 Hz, the device reproduces a wide range of sound from deep bass to clear highs. It offers wireless connectivity alongside a USB Type-C connector and supports multiple file formats (APE, FLAC, MP3, WAV, WMA) as well as MicroSD card playback. The unit includes five speakers in a compact black housing, integrated colorful illumination options (blue, green and red) and a 12,500 mAh battery for extended use.
The speaker delivers a specified 80 W RMS output which provides consistent stereo sound suitable for medium to large rooms. Broad frequency coverage (15–18,000 Hz) ensures reproduction of low-frequency content and clear mid/high frequencies. Multiple playback options — wireless streaming, USB Type-C input, and MicroSD support — make the Impressio Qubis flexible for varied audio sources and formats including lossless files. The 12,500 mAh battery enables long-lasting operation without constant charging, and the built-in illumination offers visual feedback and atmosphere control in a single portable unit.
Charge the speaker via the USB Type-C connector before first use until the battery indicator shows full. For wireless playback, pair a compatible source device following the speaker’s pairing procedure, then select the Impressio Qubis from the source device’s audio output list. For local playback, insert a MicroSD card containing supported files or connect a USB Type-C audio source. Adjust volume and illumination using the controls on the device. Monitor battery level and recharge as needed to maintain uninterrupted playback.
Place the speaker on a stable surface and avoid exposure to moisture or extreme temperatures. For best sound balance, allow some distance from walls and corners to reduce bass buildup. Use lossless formats (APE, FLAC) when available for higher fidelity, and recharge the 12,500 mAh battery after extended use to preserve battery health.
