built my first t line - check it out

I have no idea bud but Ccstang is on the thread , he may reply .

Very nice. For the record, any idea what the gross volume is for that?

From my understanding the volume is determined by multiplying the cone area, by the 1/4 length of the wave for the fs of the sub in question, this will give you the port dimensions, which a tline is nothing but 'port'.

That'd be cool, I'm curious to know if the db dynamix calc is any good?

Think he was asking cubic feet.

Yeah, I know what a t-line is, I mean how much space does the box take up externally.

6 Ways to Calculate Volume - wikiHow

Imagine it's a tube you are calculating the volume for, the area of the cone displacement of the sub by the length of the port, this will give you volume.

Calculate your box dimensions around that, taking into account the space taken up by the material used to construct the box.

The complication comes in when you add in the folds.

For a general idea, when I used the db dynamix calculator, the box came out to be 1.4 cubic feet, for one SQ HDS-208, normally it's ~.75 ported.

Are you going to sell the HO box? I would like to try it for a comparison to my box (which is built to JL specs for 12w7 v1).

I would if you interested

That's a pretty **** poor way of designing a tline really. Sometimes it can work out and other times it won't.

You can tell by looking at it? You're good ! Usually you have to hear it to be able to make that judgement.
