ideal sub fs for t-line enclosure?

[bbeljefe]

Compliance is the stiffness of the suspension, in simple terms. High compliance subs move easily and have looser suspension... ergo, they are more compliant with the movement of air around them. Low compliance subs are stiffer and thus, do not react as much to the air around them.

High compliance subs don't do so well in free air and thus, won't do so well in t-lines except at low power.

And post up some pics & vids of the one you're building. I've been too busy to do so with the little one I built but my son's car is here today and it's warm, so I'll get a video and a few pics of it.

i dont have any pics or vids as of yet, i still havent designed a box for it yet.

i just designed one that i think might work but i forgot to check for mounting depth. the inside line is 6" plus the mdf = 6.75" and it has a mounting depth of 6.5....is that gonna be too tight? should it have a lil more room to breathe?

if this checks out then ill CAD the drawing and start building

[bbeljefe]

Yeah that won't work. You need at least the same amount of space between the back of the motor and the box as the width of the butthole on the sub.

I'd prefer twice that distance if it were me building it.

DANG!

then idk how thats gonna work. how is possible to keep the port area right then? i read the quarter wave tutorial and it said to have it around 60" for a 10 and in this case i dont see how thats possible

LOL. That's the hell of building t-lines. They're basic math simple to calculate but fitting that long assed tube into the average vehicle while fitting a sub in the tube is a complete pain in the ass.

But there's a super simple solution to your problem. Actually, a couple.

First... you could invert the driver.

Second... you could build another layer of baffle for the sub to sit on. Doesn't have to be a full length baffle either.

Oh and duh... I have a perfect example of number two. I forgot to take videos today but here are a few pics of the line in Brandon's car. I had to add 1/2" to the face for these little beasts to fit in the line and cool properly...

You have to either alter port dimensions to allow a wider port, build a "chamber" for the sub or invert mount the sub.

It isn't that easy with a line because there is a limit to how narrow it can be. Therefore, there is a limit to how deep it can be. And loading chambers complicate the design entirely too much for most applications.

What are max dimensions? Because about 70sqin @ 6.5x9.5 port 100 inch line would be right about perfect. Just do a double baffle or extra baffle for the subs like you mentioned.
