any idea for a completely enclosed sub?

[rockunlimited2 10+ year member]

I am looking for a completely enclosed sub like my home sub for the back of my expedition. I like how my home sub sounds and the sub would be protected inside the box with only a port for an opening. Is this a bad idea?

It's called a 4th order BP enclosure, and it is a viable enclosure for dem deebeez.

EDIT: Didn't read the last sentence.

Don't bother, just a regular old t-line or aero port box would do ya fine.

OP,

I'd rather build a 4th order than try to take on a properly designed T-line any day. Not saying a T-line isn't better, but takes up a lot of space. A properly designed 4th or 6th order will keep the sub protected from objects in the trunk and have very good output up to about 60hz. They can get pretty big, but not as complex/expensive to build. You also could build an up or down firing regular ported box with port up or to the side....//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

A 6th order would meet his criteria as well.

Or 8th order, but as you go adding more ports the tuning gets harder. 4th order BP is a good choice for protecting the sub. But you do need it custom designed for your sub, and not all subs work well in that type of box.
