Is This box portable?

[fishkilla67 10+ year member]

I'm going to install this into the footwell of my 1991 Miata, and there are going to be 2 6.5" subs in it.

Would it be a good idea to port this box? If so, how, how big, and where would thee port be?

Each sub needs .25 cu ft, and the box itself is .249 cu ft.

What do you mean by "won't be enough"?

I've decided on these.

The guy who designed it is the guy who sells the subs, and he says it works well, as long as it's STUFFED with polyfill.

BTW, what's polyfill?

Nope, that box is WAY too small to be ported. When you port a box, that takes away from the enclosure volume. Plus, a ported enclosure usually must be a higher volume than a sealed enclosure anyway. So, the enclosure must be of higher volume to begin with and #2 the overall size is increased even more by port volume.

He probably means that it works well as a sealed enclosure when using polyfill. Polyfill makes the sub perform as if it is in a larger enclosure. 0.25 cubic foot is a very small enclosure even for a sealed enclosure - there's no way to pull it off if you port it. The port will take up space, that will decrease the volume even more. By the time you port it (with a small aeroport), you're probably looking at a 0.20 cubic foot or less. No way.

But im guessing theyre right and the box would be too small

 

[fishkilla67 10+ year member]

Alright, I won't port it then.

Yes, I realise .25 cu ft is small to begin with, but then again, so is the Miata.

Trunk subs sound like crap too, so this is about my only option.

Thanks guys.

insted of trying to put small little subs in your car, have you ever thought about doing a nice diy 2 way or 3 way active system?

^^^ He meant headrest speakers.

No, it doesn't. Wasn't offered in 1991.
