Sealed box question

[MrEwubbsZ]

Im building a seal box for my girlfriends truck Im using a Hifonics HFX12D4.

I was wondering how am i going to know what this will be tuned to?

I was going to do 19x19x9 Enclosure which is comes out to 1.33cf.

Heres the link to the sub

Its not tuned to anything, but will probably peak at the resonant freq of the vehicle.

Sealed enclosures don't have tuning lol

[MrEwubbsZ]

So it will pretty much just be whatever the truck lets it be?

Probably a dumb question. Im just not sure.

I thought sealed box are tuneable for example a large box plays lower hz better then a small box

Sealed enclosures will peak if too small, also avoid doing a perfect cube, the recommended volume will be ok for it. May help adding some damping specially with small boxes.

As everyone else has said, there's no real "tuning" for a sealed box. However, there IS an f3, and cabin gain of course. But keep in mind you won't get that hump of extra output near the frequency tuning you'd get with a ported enclosure. Sealed enclosures typically DO play lower overall than ported, but just a flatter output.
