T-line / New Box Ideas

[infkt]

Alright guys i just made a T-Line and it isnt doing to well, i calculated it out to 8.5ft of port at 176sqin tuned at 33hz but mine was 8.5ft at 165sqin, dont know if that matters that much. Also when i took the sub out of the other box and put it in the t-line it sounded like it was bottoming out but it DEFINITELY WAS NOT. So i need a T-line masters input and also whats the best truck box? as per say sub up port up? im not trying to wall this at all since its only 1 15" but i dont want to sound like a truck with 12" shallows (not knocking anyone who is doing that)

The Truck is a 02 Dodge 2500 Cummins if that helps

Could try choking the line a bit. Or stuffing it.

IMO 95s don't suit T-Lines though, how much power are you giving it?

Not all subs are built for Tlines. Some SPL subs work great in Tlines, others are sloppy as hell

I have never had a problem with line area when I start off with a small line, and work to a larger opening

This is Choked, and it starts off with a small opening and slightly flares larger towards the exit

Its Ran off a DD z-LV, not sure on how many watts its getting exactly, its enough to push it, without it getting smelly

and forever, the box i build is ruffly like that except it isnt choked,

using the same picture you have its about 2' x 2' x 3' x2' (thats not exact but a ruff idea) and i dont have that box/ space user in mine.
