sound system speaker

[chrisday1990]

Drivers side rear speaker (not door speaker) on my Emira has started blowing. The car has the upgraded sound system.


I am looking for the correct part number for the drivers door speaker used with the upgraded system, and whether it is supplied as an individual speaker or as part of a larger door assembly.


Useful to know if this is a common issue and how it is typically handled under warranty.

When I added the sound deadener to my car I wrapped this pressure relief thing in some cloth tape when reinstalling it and it helped with some of the noise. It was not attached securely prior. You can see it in the picture in the above post. It exits to the wheel well.

This is exactly what the blown speaker sound is. This vent is right beside the sub and the flaps vibrate sounding like a blown speaker.

Thank you @Honcho

Finally feel like I'm making progress!

I'll send them the photos.

Cheers!

So eliminate the flaps??

For me, I think most of the noise coming from that vent contraption was from how loosely it was fitted, it would basically fall out if touched. That looseness created a resonance noise from the subwoofer output. I think the flaps also make noise but a much lesser amount.

The sub sounded much tighter after installing the cloth tape and of course installing all of the sound deadener in the cavity.

@NicolasB The guy at KEF told me to stick a sponge in each hole until the vibration went away - now I've seen the photo, it makes sense.

However - I suspect @Rapture has hit the nail on the head with the loose fitting of the vent - although the 'rattle' sounds much deeper than the rattle of some plastic housing.

Anyone know how to gain access? (without cack handed damage!) - in other words - not using the pull and snap technique

Cheers gents

Just a quickie - the sound deadener - already fitted (just refitting here), or something extra?

There is no sound deadener applied in the doors or the rear cavities from the factory. Some of us installed sound deadener in both areas and it helps tremendously overall with both the sound of the music, and quietness inside the vehicle. I noticed I could not hear my garage door closing when pulling away after this was installed. I heard it loud and clear prior.

Access to the subwoofer is very much via the right hand rear side cover:View attachment 75955

Thanks for posting this picture. I now know where you mean.

Hi - do you have a picture of the cloth tape or can you explain what you did with this contraption? I've just removed the side panel that covers where the sub and these flaps are. The contraption is quite firm, but of course the flaps just flap around.

Also, does anyone know what this contraption is actually for?

Yeah, what did you mean by sound deadener in the cavity?

I believe it is to equalize the pressure when you close the car doors by letting air out but also keeps water out in wet conditions.

can you explain what you did with this contraption?

Not the cloth tape solution, but I found a chair seat foam pad (1 inch thick), measured the size of the vent (7in x 3.25in) and cut a piece that matched. The 1 inch thickness fit perfectly to wedge between the edge of the sub and the vent. Fit so snugly that it doesn't move at all, but breathable enough for air flow - and no more subwoofer paper slapping sound with windows open (or at volume).

So from what I’ve gathered so far, either cover the inner part of this entirely in fabric tape, or create foam inserts (or even cover the whole piece) secured with fabric tape?

Anyone got a picture of what that looks like?

Hi,

This is the tape I used. For me, the piece had a loose fit and I needed something to help with that. It was rattling pretty good from the sub. I wrapped the tape around the edge of the piece and that quieted it down a lot.

The foam sounds like a good idea also.

secured with fabric tape?

I didn't even have to secure with tape, the 1" foam was snug enough to just hold in place between the OEM Sub and the vent - I have even been back in to that area to change my speaker configuration and the foam has not moved at all - after a good amount of driving.. Did my best to quickly pull back the panel and get as good a shot as I could (piece of foam is bounded by yellow)

 

[hellograeme74]

Ok, so just ordered a piece if 1" thick high density polyurethane foam from amazon - £7. Aim to perhaps just put same fabric tape around the perimeter of the vent, then just cut the foam to size and just wedge it between the vent and the sub. Will report back in a few days - will it cure the blown speaker effect - i wonder.

Thanks for doing that - see what you mean now. I'll be trying the same - will post a picture too.

I remember easily seeing the vent and reaching the vent from the other side via taking out the rear wheel liner

The foam still should let airflow. Porous foam is what you want.

 

[hellograeme74]

Note the foam in place. Just tested it with a high bass track. I'd say there was some improvement, but can't say it was a fix.

The vent contraption does feel fairly firmly fixed. I do wonder if removing it and then perhaps covering (mummifying) the front of it in fabric tape, would have a greater effect.
