I've just built some new speaker enclosures for my car stereo and I've been wondering what the best damping material would be. Any suggestions?

Water

carpet

I meant inside the box? A few people have suggested rubber carpet underlay, foam and old rags.

Dude, water is going to make it pretty damn damp hey.

Ok enough of the smartarse replies.

i used egg cartons for mine

but then againm i have been drinkming

hmm not sure what it's called but it's the white fluffly material, bro has 2 12" in a BIG box; and he just packed all this white fluffy stuff into the box round the subs and s***, and it works like a dream.

dacron

if the box is ported there is no need for anthing inside the box.

Not ported. Just straight forward angled speaker boxes to house my 6x6" Sony drivers.

On a small box like that I wouldn't worry too much. Just seal em up with wood glue and no more gaps and carpet the outside. Should get a nice tight bass and a nice steady curve.

Well the thing is they sound ok but they have a slight "echo" sound. I'm guessing its the sound energy passing through the back of the cone and reflecting around inside the enclosure before coming back through the cone.

carpet underlay should work well, offcuts from a carpet store should cost next to nothing too

I'd go with that white fluffy speaker box damper s***. u can get it at jaycar

If it's stuffing rather than lining then it's dacron you want, cheaper from a fabrics store or some place like spotlight.

Is this the stuff you guys suggested?

you are such a nerd :D

dont bother with speakers, real cars have neon ground effects and half-cut rear springs.

Lowering a Gemini would be a very bad idea... they're already low enough as it is.

yeh, that's the stuff hunter :D

works wonders

Dude, water is going to make it pretty damn damp hey.

ahahahahha

Whats the best dampening material?


I say none is the best... reasons why?

1. It's free
2. It will do just as much as something...


I just don't think there is a real audible difference putting dacron and the like in enclosures... and I will even put $50 down on the table to whoever can tell the difference with dacron in and out of your enclosure, running your 6x9s... hell, make it $100...

Maybe you're tone deaf? :).
Seriously, you _can_ tell the difference. There's this distinct yet hard to describe effect in speakers without damping.

Umm if I remember correctly, Bullion is a car stereo installer by trade so I think he would know a million times better than someone who says "Lowering a gemini is a bad idea cos they are already so low" or "I can definitely hear and echo" even though its in a piss small box that shouldn't have even been built... I mean ffs who in the "f***" builds boxes for 6x9's? hahaha.... I bet you're running them off the head unit... cos if you had an amp and any brains you would have a sub instead of 6x9's. As if a head unit has enough power to make a box worth while... good ole 13watts per channel RMS....ffs.

AnaRoT 6*9's are for fill not bass, besides if i remember hunter's original post they were 6" speakers not 6*9's and yes i totally agree only a dong put's 6*9's or any normal mid range speaker in a box...

Hmm, well yes my brother's car's 6x9s (seriously, it's hard to fit anything more in a 240z) are in little boxes (heavy wood, not much bigger than the dimensions of the speakers). The enclosures helped significantly and even packing with dacron helped somewhat. That's just an example however, i don't think it can be written off in every situation - try it and see, it's never going to be 'omg wow its so much better' but if you could be bothered to chase that little bit extra then it's worth spending a few bucks to try it out, isn't it?


No offence either, but judge on reasons and evidence rather than reputation.

Yeah I know they are for fill, which is why you wouldn't put them in a box, cos that is only for bass applications... but thanks for your aggreance!

Edit: Yeah doober it prolly would help in that case where a sub doesn't, but sif in a Gemini... also most 6x9's are designed for free air predominantly anyway.

I am not an installer by trade :)


Anyways, as Anarot said, putting speakers in enclosures is mainly for bass replication. And if you don't want them for bass, no need for enclosures! And as he also mentioned, 99% of 6x9's are designed for free air setups...

Oh and that $100 is still up for grabs if you think it makes a difference :)

even though its in a piss small box that shouldn't have even been built... I mean ffs who in the "f***" builds boxes for 6x9's? hahaha....

Obviously you do not possess the ability to read other people's posts... god you're a tool.

The reason the speakers are in boxes is due to the fact that there's no way to place actually mount 6" speakers other than the door, which I refuse to do as it would require part of the door itself to be cut out.

Bullion is a car stereo installer by trade so I think he would know a million times better than someone who says "Lowering a gemini is a bad idea cos they are already so low"

Uh f***tard it's already low enough - any lower and you'd be hitting speed humps and probably denting your diff/sump/whatever else is in the way.

No offence either, but judge on reasons and evidence rather than reputation.

Exactly. I'm a computer technician yet you don't see me ranting on about how I can tell the difference between 60 hz and 75 Hz vertical refresh rates (I can but that's beside the point).

2. It will do just as much as something...

It may well be subjective (ie some people may have better hearing than others) but I'd rather be a little more scientific about it. Instead of listening to Anarot's bulls*** a-friend-of-a-friend-reckons style rants I'd rather get the opinion of a sound technician, or hell, even a physicist.

Lastly, Anarot, do a little research into speaker design and then come back, as it's quite obvious you know absolutely dick about them. There are a million sites which will quite clearly state why you need damping material, go find them you abrasive little s***.

$100 heh it's mine bitch

bullion: you're on. I can tell the difference in many things just by sound. I can hear all mannor of little nuances that other people can't hear. (though I am not perfect and will probably get it wrong lol)


Gemini's are notorius for being gay as speakers will hit the windows if you put them in the doors without spacers, the fuel tank if you put them in that parcel shelf without spacers. So, the only way is to build a box. Granted I wouldn't have a completely closed box and put them on the parcel shelf using the entire boot as a bass chamber.

Anarot you are a toss, give him a break it's probably the first time he's ever built a speaker box and you CAN get alot of bass out of a 6x9 my friend has done it and it's amazing how much he got from one in a box so STFU fags.

Hunter: if you want me to build you some speaker spacers that would cost you $60plus in the shops, get your desired wood, the ammount you want and some thin foam + material to cover it. I made some for my commodore that looked very professional, I can't show you because I sold them with the car. (wish I haddn't). They screw to the door and the speaker screws to it. Won't cost you a cent (except materials).

edit: got bored and made a pic of what my speaker things used to look like, sort of. They didn't look exactly like this, but very similar. click me

Hahahaha Hunter have you ever built a 4th order band pass box giving a 3bd gain between 30 and 90hz? I didn't think so, you deads***. s***, we used damping material,but that is because it is a sub ffs... Baffling is to create the effect of more space and sound absorbtion and reduce the reflected waves. How can you hear these reflections if you are using a sealed box that is MEANT to be air tight? It is meant to make the speaker work better (and therefore sound better) not directly to affect the sound. How about YOU learn a bit about speaker design, you pathetic "computer tech"... like you have to be a tech to tell the difference between 60 and 75hz refresh rates hahahaha.... you're a laugh you wanker. If you had any brains, you would cut holes in your rear parcel shelf and mount the 6x9's underneath the holes so they wouldn't foul rear window and would be in a far more suitable baffling situation. Pretty obvious really, I would have thought....

anarot at his best :D

bullion: you're on. I can tell the difference in many things just by sound. I can hear all mannor of little nuances that other people can't hear. (though I am not perfect and will probably get it wrong lol)

Giddi up :)

Instead of listening to Anarot's bulls*** a-friend-of-a-friend-reckons style rants I'd rather get the opinion of a sound technician, or hell, even a physicist

Basically, putting dacron in the enclosure slows down the sound waves, thus "tricking" the speaker it is in a larger enclosure...

A physicist will tell you it will affect the sound, a sound tech will too. But what they may not tell you, is that it is so small, that its nearly impossible to tell the difference with it in. And would only really be effective in large boxes, at low frequencies, definately not small ones with 6" woofers...

you pathetic "computer tech"...

Excuse me? Am I correct in thinking some two-bit "musician", whose music probably resembles a group of 4th graders trying to play recorder, is implying that I work at some backyard operation? You're a moron. I am the technician/sys admin for the QLD branch of a multinational software company which has 200+ clients in QLD alone. I have my own office and will soon have a company car. I suggest you go f*** yourself.

like you have to be a tech to tell the difference between 60 and 75hz refresh rates hahahaha....

That's what I said you f***ing idiot!

It may be hard to tell the difference but some of us can. It's hard to explain but it does make a noticable difference in the way it sounds.

meh you guys are so emotional, go dig up some studies on stuffing sealed boxes rather than sit here beating your chests. There was one a short while back that claimed some significant changes in characteristics, it was a measured study and even if they were a bit bias it's better than a bunch of morons saying they're better than each other.

Umm where do you think I got my info from? Reading ffs... like I said, how many of you have successfully built a 4th order bandpass box? Or even know what one is?

If you had any brains, you would cut holes in your rear parcel shelf and mount the 6x9's underneath the holes so they wouldn't foul rear window and would be in a far more suitable baffling situation. Pretty obvious really, I would have thought....

if you learned to read you stupid f***** read my post SPEAKERS DON'T FIT ON GEMINI PARCEL SHELVES WITHOUT HITTING THE FUEL TANK YOU STUPID f***

how about you get some reading skills and come back. At the moment all it seems you can do is google big words like 4th order band pass bs and ctrl+c ctrl+v

Exactly. I'm a computer technician yet you don't see me ranting on about how I can tell the difference between 60 hz and 75 Hz vertical refresh rates (I can but that's beside the point).

• I'm not a computer technician by trade (I'm a full-time student, casual supermarket deli worker).
  
• I can tell the difference between 60 and 75 Hz.
  
• I like to gloat about it.
  

Now everybody lighten up a bit, please.

if the cab sounds like it needs baffle, put baffle in it.

ffs throw the text book around some more and wake up and join the real world when you are ready.

you would be supprised what odd things people try and end up getting good sound when others wernt expecting it to work. in the studio we simply try things, if they sound bad, we know, if they sound good, we learnt a new trick.

lighten up ppls

Best speaker enclosure damping material?

take a pillow and rip the filling into bits and stuff that in the box.

that sort of thing has been done since ages past. i have it in my sub, and you'll be amazed what it does.

Whoopass like I would seriously read anything written by someone who says "I can hear nuances etc tha most people can't" ffs wanker get a life.... as if you can. Its probably all the semen in your ears rolling around.

Yeah guys, setlle down...

I hear lots of people "talking" about how they can hear the difference... do any of them care to prove it? remember, $100 :)

wool, it grows on sheep, good stuff for speakers, you may have to bag/stocking it.

you are getting an echo, bouncing around inside your box and coming back out the only way it can, through the speaker.

the same happens if you walk into an empty room/house, it echo's, when you fill it with chairs, tables, cabinets, sofa's etc. it stops the echo.

gg analrot, can't think of anything decent to say so you just say your ears are full of semen. yeah that makes sense.....on some other planet maybe.

these forums seriously need an ignore feature like IRC

/ignore anarot

So I guess there are no takers?


Shall I assume you really can't tell the difference? Or shall I assume you don't want $100 for nothing?

i can

You can what?

Whoopass and the rest of you who think you can tell the difference. So far, i've had nobody ask me for the $100, so I guess I have to assume that you're all talk?

don't revive this thread it's gay
