What it is and who it fits

This internal USB speaker pair mounts inside a desktop chassis and connects to a 9-pin F-USB header on the motherboard. It suits builders who want basic stereo output without external speakers cluttering the desk. The adhesive backing and included screws let you secure the units in tight spaces. Buyers needing surround sound or high-output audio for critical listening should look elsewhere.

Sustained-load behaviour

The integrated amplifier drives 16-core magnetic drivers with carbon-fibre diaphragms to keep distortion low during extended playback. Because power comes from the USB header, output level stays consistent as long as the motherboard supplies stable current. No thermal throttling or compression artefacts are mentioned in the data. Systems without an F-USB header cannot use the speakers at all.

Installation and common issues

Plug the connector into the header labelled F-USB and restart the PC; the supplier describes this as a two-step process. The hot-melt adhesive on the rear holds firmly on clean metal or plastic, while the screw holes provide a mechanical fallback. Misaligned header pins or a missing F-USB port are the typical reasons the speakers stay silent.

Questions about this item

Does the .6 m cable reach the F-USB header without strain?

The 1.9 ft lead connects directly to the 9-pin F-USB header on the motherboard, so no extra cable is needed.

What header must the motherboard provide for this speaker to work?

A 9-pin F-USB header is required; the speaker plugs into that single connector for both power and audio.

Can the adhesive backing stay secure on a metal chassis that gets warm?

The hot-melt double-sided adhesive on the back is designed to hold on case surfaces, and screws are also supplied for a fixed mount.
