Logitech Z623 Speaker System: How do I fix a subwoofer that has no sound?

Sun, 08 Mar 2026 17:58:08 -0700

The left/right speakers work, so it has power and is connected properly; no sound (not even a buzz) from the subwoofer. Not sure if it is a macOS configuration issue, or if I need to get in and see what's what. Any assistance you can provide would be appreciated.

Logitech Z623 Speaker System: Volume knob causes right speaker to drop out

Thu, 25 May 2023 19:50:15 -0700

I suspect this is a general issue that could happen to any device with an analogue volume knob, because I feel like I've experienced this issue more than a few times in my life. But I created a device page for this anyway.

The right speaker cuts out entirely, but if I tap the volume knob, the sound comes back. The left speaker doesn't have an issue.

FWIW, the right speaker houses all the controls for the system, the power button, volume, and bass control, you may be able to tell from the image. The right speaker connects down to the bass speaker with some kind of data cable , and the bass speaker connects to power, and also the audio input.

I've read many pages on cleaning out volume "potentiometers" to clear up crackling, and while I do hear crackling when I rotate the knob, I was unable to clear up the crackling by repeatedly turning the knob back and forth, maybe more in depth cleaning is necessary.

I've actually got some contact cleaner, but haven't opened up the speaker to try and clean out the volume knob yet, I thought I'd ask first.

Mainly; I'm curious if a dirty potentiometer is known to cause just one speaker channel to drop out completely, or could this be another problem?

Logitech Z623 Speaker System: Logitech Z623 Replacement Speakers

Thu, 13 Nov 2025 18:15:12 -0700

Does anyone know where I can get replacement drivers for the satellite speakers or what the model number even is? I’m open to using comparable or better replacement speakers as long as they fit and have a similar resistance. This is all I need to get my speakers working again.

Note: The “Choose a Device” section at the top is stupid! I couldn’t find the model number for the speakers I’m asking about so I picked a random logitech product… Please fix this.
