- Welcome to our AudioTalk, where I am diving deep into the world of audio. In this video, we explore the crucial topic of damping in speaker cabinets. Whether you're a seasoned DIY speaker builder or just curious about elevating your audio setup, understanding damping is the key to achieving pristine sound.
We've divided the process into two essential tasks:
1. Acoustic Damping: Discover how to tame those unruly sound waves inside your cabinet. We explore the benefits of materials like egg crate foam and polyester fill, perfect for bass reflex and sealed cabinets, respectively. Learn how to fine-tune your damping for optimal sound quality through listening tests.
2. Mechanical Damping: Eliminate those pesky rattles and vibrations inside your cabinet. We'll guide you through precision cabinet cutting, the advantages of Medium-Density Fiberboard (MDF) panels, and how to use internal damping materials effectively. Secure your components and seal those joints for a rock-solid, vibration-free cabinet.
Whether you're crafting your dream speakers or seeking to enhance your existing setup, this video provides the insights and tips you need to achieve audio perfection.

In my 60 years in audio and music this is one of the best tutorials I've seen. Keep them coming. Thanks
Thank you so much, thats very motivating!!!
Why does everyone keep saying dampening... get your terms right!!! Its DAMPING!
Good to see you back.
Thanks for a great tutorial!
I just finished building a pair of ported boxes. I tried them with no damping this evening, to see how they behave...
Will be adding damping tomorrow.
Then i can experiment with the length of the port tube.
Silicone sealant is a great tip!
My cutting is not great..
Used draft excluder tape in a couple of bad gaps.
Speaker gaskets are another potential leaking problem.
Thanks for the excellent explanation! Such a patient and thorough delivery. 🙏
A bit disappointing material, a lot of obvious truths and no valuable information such as how to dampen the midrange and tweeter casings, what materials dampen what frequencies, e.g. foams of different densities, etc.
Yes and unclear about basstube damping. Often he gets confusing or unclear.
Stopped watching at point “egg crate foam works good in room acoustics.”
It does tho
Damping material around/on the basstube? Or what do you mean?
Thing is... it helps whit subs too. The egg crate style stuff indeed does a pretty good job in them.
Bracing should never divide a panel into equal parts. Ever. You do not want to trade a single resonator for 2 resonator whith higher fequency.
Generally speaking plastic reflex ports als love a good layer of bitumen on the outside . Makes a difference.
Allso its worth to consider to have a 90 degree turn in your port , dividing the port in a 2/3 to 1/3 ratio.
Due to cancellation , its best if the inner end of the port is indeed near the verry center of the box . Best to size the port in a way that it has a large surface area , but.. its first resonance is outside of the freqvency range you wish to play. Hence why 3 way speakers kindof have an advantage. You can cross over before the port harmonics.
You can use a fine mesh material like mosquito net to ensure your filling material does not move around.
Best to design your box whit internal edge lengths that got no common resonance.
You should round off external edges.
The outside of the speaker should be carpeted. Whit something heavy and fluffy.
You never should mount the driver in the verry center.
Watt's are cheap now, you want quality over quantity! "efficient" loudspeakers suck!
I love this take so much
I make my speaker cabinets out of mdf and use industrial flooring adhesive to adhere solid oak on the outside and I make the tops and bottoms 3" thick and I spray the inside with flex seal and adhere thick carpet pad on inside walls then I use Rockwell for a fill partly i also angle 45° pieces on the top and bottom on the inside my speakers weigh 80lbs but they sound amazing. I don't like poly fill its doesn't work as well as Rockwell or fiberglass. But I am big into madd loaded speakers if you heard them yet can hear all love i put into them.
I can imagine that works very well
"Rockwell"?? You mean "rock wool"?
@@jgfergus yeah my autocorrect changes things and sometimes I don't catch it but thanks Mr. Obvious
@@BostonMike68 I was just asking a question. No need to get all defensive.
Hi sir I need your contact to learn more about audio product making
Hi, nice and informative video. I have built a sealed 10 litters enclosure for the mid bass for my car. Want to how much polyfill can we add to it.
Thank you, if you go to 3;40 in the video it will give you the optimal procedure. What would sound best Heavy, typical or minimal on the dampening material with no software calculation and being a subjective experience is not possible, so experimenting is the best way. Typical is half full.
@@AudioTalk Will watch the video again. Thanks for the reply.
Polyester is less friable then fiber glass and won't interfere as much with that tight gap between the voice coil/magnet
Thank you for this! I built a nearly square cabinet to be used as a subwoofer. I did not have a subwoofer to purposely build it. I had two ports that I thought I could tune with the length of the tubes. But then of course I did the math. Then a friend gave me a plate amp that was blown and I fixed that.. So that was also an addition. So now I had to try to purchase subwoofer to fit the plate amp. The plate amp is too powerful for the sub.
As you're reading this you can tell this is very fun for me I'm learning as I'm going and I'm acquiring parts as they come to me and as I find around in my shop.
So I purchased a subwoofer that fits the cabinet and I made it portless back in the day we called it acoustic suspension. And I got what I wanted out of my system I wanted to hear the lows clearer better not moving too much air not automotive trunk rattling. As soon as I plug the ports properly I got tones that I could adjust and work on and it became wonderful for me for home theater and also playing music.
And most of my life there's never been enough base. So the systems I build for myself are all 2.1 now. If it's 50 watts per channel then it's double for the subwoofer. However this subwoofer has the plate amp that I installed. And once I plug the ports the sub sounded great especially with midlows and sub frequencies. Ceiling the cabinet basically tame the beast and gave me more defined low end.
Now I hear your video here and you gave me the perfect solution to get out some of the higher low end tones that hoooot . I happen to have the correct foam with me and I'm looking forward to tuning my ever evolving subwoofer cabinet to make it sound even better.
Thank you for this! Obviously this one wasn't a project that I built a cabinet for a speaker and did all the math. This was a cobbled up fun project from scrap that I had around. So I really appreciate your insight in this and someone actually talking about speakers that aren't ported.
Very informative. I bought a 5.1 speaker system that is cheap and bad, but I think I can get it to sound better by dampening inside. The wood is very thin and there is a lot of echo when you knock on the speakers, so they were made cheap without any mechanical or acoustic dampening. It will be a fun project.
Thank you, That is all I have got to say.
why not just make a cabinet with slate pieces inside? they not only damp but also make walls super strong and rigid. and its cheaper than wool
Good stuff..
The title is correct: Speaker Cabinet Damping. But you keep saying dampening. Dampening means to make something slightly wet.
@@jacktoughdamp is okay, dampen is okay, dampening does not mean the same thing as damping.
Maybe start by using the correct terminology?
It should be referred to as "DAMPING", not "DampENing".
AFAIK we are not dealing with moisture issues here, LOL.
On what basis are you saying this........did you measure with and without......just blablablabla
So you saying you have no clue... Just talking... Get a calibrated mic and back up what your saying.
I stopped watching when we had to explain that port = tube. LOL!
