i have 10" jensen sub's, but if any one knows any thing about these speakers, at least a little to help me make a box it would really help heres the specs.

0.75 cubic feet
1 3" round port that is 10" long.
That's tuned to 45hz so it won't give you deep-deep bass but it will give you punch.

If you have 2 subs then it is 1.5 cubic feet 2 3" x 10" ports (Do not do 1 6" it doesn't work like that)

A few other comments:
"(Re)DC(R) 3.49cricle figure" The circle figure is the Greek Omega which means "ohm"
and
"(Bi) 13.26Tm" It's Bl not Bi

Any other questions, please post 'em

um ok what you just said went way over my head. I have some idea of what some of that stuff is like the port, but for the other stuff that i listed i just put up thier because it was in the manuale for the speaker and i thought it would help. im going right now to find out what all those things mean.

xmax of 4mm, dang thats small, means the distance the woofer moves up and down.

Whoa, Okay what you just posted is a bandpass box (thw woofer is inside the box with 2 chambers to work in). I just played with the bandpass box set-up on winISD and I don't think you will yield many benefits from a bandpass (plus with a bandpass you can't hear when the woofer is distorting and you run a much higher risk of blowing the woofer - especially considering its a Jensen woofer rated @ 150wrms)

A simple ported will work fine for you. Cubic feet just means the air-space the woofer will be acting on. I've done some recalculation and 1 cubic foot will probably work better for you.

Here is what I have worked out.
If you use 3/4" woodexternal dimensions)
14" high.
21" Wide.
9.5" deep.

If you use 1" woodexternal dimensions)
15" high
22" wide
9.5" deep.

3"Diameter x 8"long port

I hope this helps
The numbers you posted earlier are very helpful for designing a box.

2 more questions:
(1) How many subs do you have?
(2) What are some of your trunk measurements (so we might be able to help you find a custom fit?)

Damn, I was looking for this awhile back with an Eclipse sub and I was just going in circles and still got no where, maltese where were you before? lol

Did you post the Theile Small Parameters like Lumina Kid did? If yes I'm surprised no-one helped you.

Go to www.linearteam.org and download WinISD. It works well for a free boxbuilding program.

I problem with WinISD is it doesn't compensate for driver displacement or port displacement. I have made a sheet on my computer that does all of that for me, so I am accurate within a couple of cubic inches.

So the box dimensions I offered Lumina Kid are a little bigger than 1 cubic foot on the inside but after the speaker and port have been added its pretty close to 1 cube.
