Sound Deadener Recommendations

Cool - looks like we work in overlapping industries. I'm not in the acoustics business entirely, but it is part of what we do. I do commercial A/V work & we usually farm that stuff out to folks like you. We're more of a design and integration business. We do install dampers on some of our mounts (typically elastomers), but it's difficult to convince some of our customers that they need it - even when their walls vibrate enough to feel it. I did a full treatment on a fire station a few months ago though. I hope we can keep farming that stuff out

That techlite stuff looks pretty cool - never seen it before. Looks like a nice, 1-piece treatment for walls.

 

People on here wanting CLD should jump on this. Second Skin Audio has some quality materials.

 

$190 for 30 sqft for Damplifier Pro? That's 30% higher than Dynamat extreme. Even with the 20% off, it's still 10% higher than dynamat.

 

Yeah, that is pretty spendy at $6.34/sq foot and that's on sale! Knu Kolossus tested better and is far cheaper for a comparable amount at its retail price - 35 sq ft for $140 for $4.00/sq foot. I'd go for the Knu over the Damplifier Pro all day. Knu makes a lot of nice stuff at great prices. Their cable is arguably the best in the business - and aggressively priced.

 

Dynamat Extreme can be had for $150 for 36 sqft, which isn't bad. Their cable?

I bought regular Damplifier. Go for that if the Pro cost is too much. You only need 25% coverage. What matters most is the MLV. That's what keeps the road noise out and the music in.

 

I think they recommend putting ccf in between them

 

Yes, but the MLV makes the most difference. CLD is just to keep the metal in your vehicle from vibrating and making noise. That's why regular Damplifier is good enough. You don't need to splurge on the Damplifier Pro. You can get CCF from foam factory online website for cheap. You don't need to buy the name brand CCF that costs more.

 

Thanks for the responses. I won't worry about the CLD tears then. It's Noico 80mil.

Yes, the actuator is for the rear window.

Here's how I did the MLV and 300mil foam. I copied the stock carpet thing so the holes are way oversized which reduces some effectiveness. I'll probably patch it up at some point.


The Noico foam is insanely sticky. It's adhered to the other side.


I also caulked the vents as suggested:


It's amazing how small the magnets are on the stock speakers and how light they are. Here are the fronts compared to the OEM+ speakers:

 

Negative, the wires run underneath the side of the seat, that little plastic runner you step on (forgot the name of it) the panels go back fairly easy. Once you figure out the dismantling of it, putting it back together is a breeze

 

Best bang for the buck, by far.
Can be messy, but worth the performance / cost ratio.

 

Are you referring to the CLD being messy? I've never heard of knukonceptz.

 

Yes.
The butyl is a little softer and can get stringy.
They have been around for years. They started in home Audio and widened their SKU range to auto. Great quality stuff.

 

Does anyone have any really good resources for how to videos?

I haven't Googled it yet but I'm sure I'll find something. This seems like advice and direction that could vary pretty widely though.

 

This one's been passed around a good bit



I'm more of a reader when it comes to such things, but this is a good example

 

Thanks, this guy's videos are pretty good. Anyone have any experience with an all in one solution? I saw one of his related videos about Sound Skin .

 

There is no all in one solution that I know of. 2nd skin makes luxury liner which is MLV and CCF already glued together, but it's pretty thick. No way I could get that in 1st gen doors - can't speak for the rest.

CLD to lower resonant frequencies and control vibration. MLV to block incoming noise. CCF for decoupling & thermal insulation. No way to do all that in one go as a vehicle isn't one big flat sheet of metal.

 

This is what I've been thinking as well. Everyone says that the only way to block sound is with MLV and CCF, but how the eff does one fit that behind a 1st get door panel? There's very little room between the door panel and the inner door skin.

 

A cross-section of my 1st gen doors

From the inside out: 1/16" neoprene, 1/8" MLV, 1/16" neoprene, CLD (inner and outer skins). Also using CLD on the door card.
