Size of box for 6"x9" ?

[marcopolo 10+ year member]

Hi!

Can someone tell me what should be the size of a (sealed) box for a 6"x9" speaker that I have in my rear deck. I must make some box behind them couse my sub is tearing their surrounds off when played on full. I will now make a wooden box behind them myself (I couldn't get any plastic pre-made ones in my country!!), I just don't know how big should they be. An installer in our biggest audio shop told me that they would need about 7L of space.

Thanx in advance.

what's a leiter?

some sort of communist measurement, i assume //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i've seen some pre-fab 6x9 boxes, and they looked like about a quarter cubic foot. if you can convert that to metric, there's your awnser.

Hey, don't you communist me! The whole continent uses liters and centimetres instead of "your" feets and inches.

Anyway, from my calculations, 0.25 cubic feet is exactly 7 liters, as much volume as the installer told me. Maybe I'll trust him better from now on....

Thanx for the help, bye!

you can get a foam baffle that will help this.

the above would probably be a little cheaper as well...check out http://www.thezeb.com or some other online sites and see how much the foam baffle would be...good luck

And how does this foam baffle look like? I mean what shape it has? I cannot buy it anywhere, because in every store that I have been in they've told me that it is not sold anywhere in my country. But I can always make it myself if I would only know how does it look and so. I once tried to put a pyramid foam behind the speakers but they would still jump up a lot because of the sub.

And won't the foam just behind the speaker affect speaker's mid-range response and quality (I have them high passed at 140Hz) ?

Thanx in advance.
