Speaker buzz from front centre dashboard Bose speaker
The front speaker may buzz notably on low quality phone calls or music with high mid range.
Here’s what I did to resolve it:
1) Remove the speaker cover. Use a trim tool to carefully work round it and lever it out. Don’t apply too much pressure as the clips are plastic and break easily.
2) Unscrew the six bolts. Remove the plastic frame.
3) Unscrew the 3 screws for the speaker.
4) Unplug the speaker.
5) Clean out all debris. Lots gets into the speaker box.
6) Check the wires to the speaker and if they are slightly touching the cone where they are not directly attached, gently move them off the cone to prevent vibration.
7) Clean the places where the plastic frame sits.
8) Check the spongy mounts on the speaker, these isolated the speaker and stop direct plastic to plastic contact. Check for damage.
9) Plug the speaker in and screw back into place, check for vibrations or buzzing. Press firmly on the housing to see where it comes from. Tighten or loosen the screws as appropriate. Overtightening may force plastic on plastic contact and cause buzzing as the sponge isolator on the speaker is compressed too much.
10) Replace the plastic frame and tighten all 6 bolts, do one at a time and check for vibrations. Over-tightening again may cause vibrations.
11) Replace the speaker grill. Keep banging where each clip is in turn until it’s firmly seated.
12) Check for vibrations and buzzing. Hopefully now gone.
Let me know if this worked for you, or if you have any further tips on speaker vibration!
Check the wires are not touching the cone where they are not directly attached. Check the speaker resonance chamber for debris. Small stones can vibrate and buzz. Bolts to remove grill. Far right is hardest to access. Vacuuming with this cover on traps debris in these holes. When you stop they just fall back into the speaker. It’s these debris that vibrate on the speaker. Check the speaker for damage and debris. Check the gap here. There should be no contact plastic to plastic. Reseating the speaker does help. It has spongy isolators which are designed to prevent vibration. These can compress over time and overtightening the speaker can cause too much plastic on plastic contact. Causing buzzing and vibration. 6 bolts to remove the plastic frame.
Great post @Bladerunner . I recently spent some time trying to isolate some of the lingering vibrations with the sound system in my A8 and found that the speaker grills in general, namely the center and three back, were a source of vibration. I ended up picking up some self adhesive felt sheets from my local craft store (https://www.hobbylobby.com/Crafts-Ho...-12%22/p/20782) and lining all the outside edges and clips of these grills. With the center speaker being the biggest offender during conference calls I also added additional felt on the plastic base to prevent any plastic to plastic contact like you mentioned. So far so good but I may go back and remove the speaker altogether and check underneath like you did. Right now the next vibration offender I've uncovered is the rear sun shade. Would love to hear any other tricks to address this or other areas.
