How to tune a box??

[dab86 10+ year member]

Im really new to all this so dont mind my stupidly but i have a question.

I got two 15 inch RE audio subs in a ported box. Do you tune the box or is it automatically tuned from the way you build it? My box has 4.0 cubic feet per chamber.

depends on the port. i.e. lenghtxwidthxheight

Call Greg from RE and make him "help you" design a box. Then laugh and tell him Tuan said to do so. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Greg has many pre-designed enclosures for your sub that he can instantly email to you.

My final question is my subs can hit pretty low bass. But how can i make the low deep bass sound louder? The overall bass is really loud but when it hits the real low bass it doesnt seem as loud. Is there a way you can fix that using any of the amp controls settings?

turn down the bass boost(off) and up slightly on the gain...

You need 3 things:

1)Net airspace in the enclosure in cubic INCHES after all displacements

2)Port area

3)Port length

Take the square root of your port area multiplied by .823

Then add you port length to that

Multiply that by your net airsapce in cubic inches

184000000 x port area

Devide that by the number you saved from above

Square root that number and multiply by .159

And this number you have now is your tuning
