i was readin a mag a while ago an a car with a top notch system had this cloth thing behind the speakers htey like laid the cloth out and put the speaker on top of it so it would completey seal the speaker, what was it??
it makes the sound more crisp??
if anyone knows or am i just losin it

Might just be a form of sound deadening, i mean a cloth isn't hard enough or sealed enough to be used to make a speaker box.

what kinda speakers?

if it's inside a sub box and it's white and fluffy, it's just dacron filling, supposedly to fool a sub into "thinking" or acting as if the box is a little larger, but it's not an exact science, and it's a matter of opinion as to wether it works or not

if it's just a thin flat panel, it may be an aperiodic membrane..... f**k if i know how an AP membrane works, but from what i've read, they're a bit of a b**ch to set up right

otherwise, i'd guess the fabric you're talking about is a waterproof fabric put over the back ofthe speaker as a splashguard in doors

i know abt the foam in the sub box trick.
this cloth thing was put behind the speakers in the doors and the parcel shelf, was sorta of a gunmetal grey colour and very stiff.
i can't find the damn mag now.
thanks

There is another type of technique used for installing a sub, where they put a skin on the front cone, and behind the magnet / basket. I'm not all that sure of it, although it is supposed to make the best quality sound. There was an article in a HOT4's once (yeah I know, leave it alone).

I'm not even sure what it's called. Look it up?
