I've updated my single 12" T-line recently, got a pair of Pioneers 10's (ts-w257D2) and adapted them in a new baffle mount.

They sound pretty clear and Loud on the 35-45hz range, and peaks at the blurry's 50-51hertz :)) you can feel the air moving at 30hz to 25hz

So I'm finally rejoining the T-Line game. Since my Xterra doesn't have room for a full on T-Line I've gotten some help and will be building an offset driver tapered T-Line for a pair of Eminence LAB 12's. Fs of 22hz, I'm excited to see what kind of lows this will put out.

Here's a sketchup of it. Don't mind the uncentered holes in the bracing, it probably won't be circles, just wanted to get the point across.

looks interesting. bit overkill on the bracing for a pair of 12's.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through.

I'm wanting to build one of these boxes for a pair of fosgate p3 12s. I'm confused with all the math here so I was curious if someone could possibly draw up a couple designs for me. It needs to be no more than 48" wide. Height and depth are not a problem cuz its going in an suv. But the smaller the better. Would like it to be tuned around 30hz.. would be cool if each sub had its own port but not necessary. .

Thinkin about doing a T line for a pair of Exodus Anarchy's I have laying around, just because. Figure it should do pretty well on my DC 5k.

At 16 ohms :nuts:

"Clipping" is the biggest forum boner now. It's like witchcraft... it automatically explains just about everything people don't understand.

Want to stay informed... Thinking about TLine'ing HDC3 12... Sorry, I haven't read all 70 pages yet, as i have to get back to work, but can I run the subwoofer's RMS power? Or will I bottom up the woofer and screw something up? I see what 300RMS on an 18 can do, I can just imagine what 1500RMS on a 12 would do... I'm willing to build, if they come....

I don't see why not. I've built a number of them and I've yet to run a sub at or below it's RMS in one.
