2.1 USB speaker with 9" subwoofer

The cinnkeyi S217 is a 2.1 computer speaker system powered by USB and driven by a 9-inch subwoofer. Dual 4.7-inch mid-treble satellites handle higher frequencies. A touch remote and side volume knob give quick control. Dynamic RGB lighting runs automatically. The package suits desktop users who want bass presence without a separate amplifier.

Connectivity limited to 3.5 mm, USB and SD

Audio enters through a single 3.5 mm auxiliary jack; the USB port supplies power only. An SD card slot accepts cards up to 32 GB for direct playback. No Bluetooth, Wi-Fi or digital audio inputs are provided. The subwoofer level is adjusted with a dedicated knob, while RGB effects cannot be customised manually.

Check for 3.5 mm output and free USB port

Verify that your source device has a 3.5 mm headphone or line-out jack. Ensure a spare USB-A port is available for power. The subwoofer measures 3.7 by 7.0 by 5.9 inches and weighs 1.742 kilograms, so confirm desk space. Satellite RMS power is 16 watts each, total output 16 watts, with a signal-to-noise ratio above 75 dB and frequency response from 50 Hz to 20 kHz.

Questions about this item

Should I choose the 2.1 configuration with the 9" subwoofer or a different setup?

The 2.1 configuration with a 9" subwoofer and dual 4.7" satellites provides dedicated bass and stereo separation, ideal for desktop use where space allows for the separate subwoofer unit.

What does the 16 W total power rating mean for actual listening volume?

The 16 W total output (8 W subwoofer plus 4 W per satellite) drives the system to loud, clear levels suitable for near-field PC listening, movies, and music without distortion at typical distances.

How does the 3.5 mm input and USB power work together in practice?

Connect the 3.5 mm audio cable first for signal, then plug the USB cable into a 5 V port for power; the system also plays directly from SD cards up to 32 GB without a host device.
