Resonix sound deadening CLD (2 Viewers)

[davedave]

Does anyone have experience with this brand? I know plenty of folks here have used Dynamat, Hushmat, Kilmat etc. I’ve been researching CLD squares, and I’ve found a few places where everyone swears by Resonix. According to their marketing materials, resonix is far more effective per dollar. However, it’s also MUCH more expensive than the others per square ft. They say you can use less of it to achieve the same results with the competitors’ products, but I can’t find any third party research or comparisons that I trust. This seems to be a field with not a lot of industry-wide certifications or testing. Does anyone here have experience with resonix CLD squares (or any of their other products)? I’m thinking about biting the bullet, but their marketing pages really make it seem too good to be true.

After my experience of using Kilmat in my pickup, I would say use whatever CLD fits your budget. It will help with noise in the cab, which is the end game.
Cheers!

Wondering the same thing, looked it up and found your thread. Did you end up using any sound deadener products?

Nope, never got around to it. It sounds like a job that’s a pain so I want to make sure I have the right stuff. Still seems like Resonix has the most rabid supporters, but the whole thing seems a little suspect.

I understand. Not saying this is you, but I have let the desire to have the "best" stop me from starting projects in the past and ended up wishing I had just done something even if it wasn't perfect.

I don't see myself pulling the trigger on their 3k SUV package- have you found a plausible second best/more commonly used option? I REALLY liked sounddeadenershowdown, their package was well under 1k and seemed top of the line. I'm thinking anything reputable around that price range and same approach (cld plus deadener) should be a good option.

lol well that’s exactly how I am with a lot of projects — definitely a bad habit. I think if I do it, I’ll end up going with kilmat or hushmat, as I’ve seen lots of folks use those. Might be helpful to stop by a car audio place to see if they have any recommendations. Let me know what you end up choosing!

I will likely do the same, I did find this thread really helpful for products and amounts. Interesting link about door seals there too.

Sound deadening project for the LX 450!

I decided it's time to replace my gross carpet (prev owner smoked) with a new OEM one, and do some sound deadening! I've done a lot of reading of previous posts and on Google. From what I gather so far, the recommendation is generally 3 stages. I saw that carbuilders have a great kit but they're...

The guy who owns it is pretty active on the car av reddit. Used to drool over some of the audio builds he'd do. Any deadening is better than none.

I use Down4soundshop sound deadner. I would say this 80 is about 98% covered in layers of sound deadner.

When I see pics of interior panels covered with CLD products I can't help but wonder if the person doing it knows how they work or read the instructions?

CLD tiles are strictly for resonance. 25% coverage is plenty and curved/compound formed surfaces don't need any.

25% CLD, 1/8" closed cell foam and 1/8" mass loaded vinyl will make any vehicle dead silent inside.

I've been using sound deadner since the early 90s back when dynamat first came out. So I'm not sure what your implying. I worked in car audio for 20 years still do some car audio but no big builds or spl vehicles. A well deadened vehicle sounds so good and yes you can get by with a little. And you say formed metal?doesn't need any? Because it's formed means it will not resonate? How do you know this ? Any testing?

If you've been doing it a long time do you remember Soundeadenershowdown.com?

A CLD tile is vibration dampener. It's just like the harmonic balancer on your engine's crankshaft or that big iron and rubber thing hanging off the back of your 80 series transfercase.

When a material starts to resonate (vibrate) the CLD tile interrupts it, actively changing the resonate frequency of the material it's attached to.

There is no reason whatsoever to cover a surface in CLD tiles. They stop resonance, they don't stop sound from traveling through the body.

Closed cell foam and mass loaded vinyl are a good combo to absorb sound at different frequencies.

-CLD tiles stop resonance

-Additional materials are required to stop sound outside of what the CLD tiles accomplish.

Pretty sure there wasn't internet in the early 90s.
I know what it does.
I have used just enough say speaker mounting location and behind speaker location.
I've done the whole inside of the doors with spray dynamite.
Also for the most part of the inside of the doors with the tiles
Along with the outside of the door where the door panel attaches covering all holes.
I have also used dynamat wood where it's sandwich between two pieces of wood s*** was expensive.
Anyway you do it how you want I will continue to do it the way I want.

Spray dynamite would be a great option lol

You can't buy from them anymore, but the page is archived here:

Sound Deadener Showdown | Your Vehicle Quiet

Vehicle sound deadening is a process, not a product. Vibration dampers, barriers, acoustic foams and decouplers each play a role. Learn what they do and how to use them. Do it once, do it right, enjoy the results.

I don't know about adding a half ton of CLD (my cruiser is heavy enough), but I got a small but noticeable improvement in my own rig just by replacing the butyl putty between the door skins and the internal stiffener bar. The OEM stuff had dried and shrank and was no longer making contact. I'm not saying it's dead quiet now, but that stuff is there for a reason and any of the original stuff is probably long past being effective in most 80s.

I've always suspected that this is one of those 80/20 situations where you can get 80% of the results with 20% of the material if you use it wisely. That said, I'm not a car audio expert.

This looks amazing! I would love to achieve this level of sound treatment. Can you share what you did that isn't visible in the pics? Did you put down CLD, or do anything with underbody and wheel wells? Also, I see some of the material is not reflective like the rest - what types of material are used here?
