Default Centerd dash speaker buzz/rattle

Anyone else have this issue? Mine seems to be worst when listening to talk radio with heavy mid-range, even at low volume the speaker is rattling pretty badly.

Its under warranty, but is this a rapaiable thing or just a design flaw I should try and fix with dynamat?

What's your MMI version? I seem to recall this was one of the "fixes" in one of the various MMI update threads?

Regardless I'd ask it to be fixed - especially if you can demo it for the SA, do it.

yes i too have the same issue, but even when the radio/media player is off. The noise kinda sounds like radio interference; i thought it was my cell phone, but happens intermittently....

Mine is clearly speaker rattle against the speaker cover, during heavy midrange like talkshows. I can put my hand on the cover and it stops buzzing...

Yes I also have this, I listen to a lot of podcasts. I have to turn the volume to a silly low level to combat it.

Use of felt is helpful

Nice, thank you!

I am thinking of trying that. Ive had speaker rattle before in other cars, adn the dealers typically just replace the speaker, which is not the issue!

Additional you can use felt between the grid and holder. In the picture both are still "untreated"

The center grill of my B&O system had a resonance and the dealer fixed it by applying some damping material. They said they had seen the issue on other C7 cars.

I noticed mine rattling a lot when I was talking to someone on the phone. The radio rare produced the same noise.
I took it to the dealer and they replaced the center vents and added some dampening material to it somewhere.
It didn't completely stop but it quieted it down a lot.

I have the Bose system and have/had this issue ever since I got the car. Did two trips to dealer. After the first one they applied some dampening material around the speaker but that didn't address the problem.
The second time they told me the resonance was coming off the speaker itself, not anything around it, so they replaced the speaker. That made it a little better but didn't solve it.

At the end I gave up. The entire sound system is sub par to begin with.

I have this problem too and like others its with talk radio. Has anyone tried the felt idea and do you have instructions on how to do this OR is this something the dealer can do?

Thanks,
Ed

I agree. Bose may be a bit "boomier" but overall the balance and clarity were much better on the $850 B&O I had in my A4.

Had the same issue, particularly noticable when listening to talk radio and during phone calls. Dealer fixed it under warranty, combination of replacing the speaker and MMI upgrade. Issue completely resolved. Don't attempt the felt thing if still under warranty, let dealer fix it!
