Make a hole on a sealed box??

[overture_1928]

Hi guyss,

I'm a total newbie in the form and need some input..

I have 2 12" on my trunk in a sealed box...

i want to have that low-not punchy-softer kick on the bass..

and because i have a sealed box, it sounds too punchy..

now the question is, do you guys think its a bad idea to make a hole

out of my sealed box?

because what i know is you can have that softer kick if you have it ported?

btw, the box is not that big, not big at all...

i fit that in my 94 prelude...

i purposely made it just good/big enough to snug it in the wheel well...

suggestions?

Thanksss!!

If you want a ported enclosure you're going to need to start from scratch.

Noooooooooooooooooooooooo. It is not a wise idea to punch a hole in a sealed box. That is not how a ported box works. Get a person on this forum to make u a ported box if u really want one. And I think if u have a bigger sealed box, the punches wont be that hard

i had a sealed box with 2 12's in it, and rather than buy a new ported box, i just took one of the subs out so the 2nd sub hole would be the port

i gained 30db

putting a hole in a sealed box will not fix what you want it will simply give you the sound of a sealed box with a hole it ....you are better off making a ported enclosure or slightly larger sealed enclosure to give you a bit more boom

Word

If you just cut a hole in a sealed box, You have a sealed box with a hole in it.

Ports must be built to specs to be tuned properly.

Go to Wal-Marrt and get pillow stuffing

Pillow stuffing = Poly Fill

APX. 1lb per cuft

I think thats right //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

i wonder if anyone's ever tried one of those cheesecloth airline pillows

would probably work, and would keep the fill out of your voicecoils

yes if you want that bass you gotta let the subs breathe more meaning....your box must be bigger....the bigger the box the sound will be lower.....in more simpler terms...lol

how much cubic feet does polyfill give you???whats the rule of thumb..is there anyone on here who can give me box plans for a seald inclouser

Tell us what specific subwoofers you have. Brand and model number.

Polyfill helps make minor adjustments in the sound. Don't use it to attempt to use an improperly designed enclosure sound better. The best fix for that is to build a proper sized enclosure.
