Logitech Z407 Bluetooth computer speakers with subwoofer and wireless control Repair

The Logitech Z407 is a 2.1 desktop speaker system that delivers up to 80 watts of total power using Digital Signal Processing (DSP) for balanced, lifelike sound. A ported, down-firing subwoofer provides 20 watts of dedicated bass for deeper low-end response while two satellite speakers reproduce mids and highs. The system includes a wireless multifunction control dial for volume and source switching and supports Bluetooth wireless connectivity. The speakers use a durable, reinforced plastic enclosure and sturdy grille elements to withstand everyday desktop use.

The Logitech Z407 Bluetooth computer speakers with subwoofer and wireless control can be identified by the model number (M/N RR0018). The model label is on the underside of the subwoofer and on the base/underside of one satellite speaker. This label lists the model (M/N), part (P/N), and serial (S/N) numbers.
