how big is that box, port included?
any numbers or videos?

Looks sick!

I want to see some numbers.

Mickey B here is a post from stratusrt01 on the t-line box. I didnt build this box just to let you guys know as it seems some of you may think.

heres the formula, its simple, you would just need a pen , paper, and calculator. Quarter wave is all based on speed of sound, and length of the sound wave.

Sound travels at 1130ft / sec

to calculate length of Freq Devide 1130 / (freq) say 30hz

1130/ 30 = 37.66 ft long Full wave length But we need to devide this by 4- for 1/4 wave wich equals= 9.41ft long

Pretty long huh? And the worst part is, to have a true T-line, you need to keep the port/tunnel/line - a Line, that equals Cone area, or pretty close to it. If you have a 10" The average SD/Cone area is about 50-60sq inches (to find SD in inches, you measure the cone, by useing a tape measure, and measure from middle of surround, to middle of surround on opposite side) 10" is usually close to 9"- 8.5"-9". This is where Pie comes in 9"/2 = 4.5-------- 4.5"x 4.5"x 3.14" = 63.58sq"

That is your Port AREA ( usually round this number Down- say 60sq")

So, a Tline for a 10" with a Fs of 30hz, and a cone area of About 60sq inches, will be about 9.25ft-9.5ft long (rounded) Its okay to be a little off, because this is car audio tlines, the cars accoustics will not notice it, because of cabin gain. But, when building a t-line for a sub based on Fs, you need to keep in mind the speakers Qts, and Qms, they should be low for SQ, Qts of .40 and lower, and Qms of 7 and lower will work great. Qts is speakers total quality in Ratio to its electrical, and mechanical characteristics, Qms is the Mechanical ratio.

still no numbers?

what's the height, width and depth?

Legacy's are great cars for a trunk install, and an awesome car as well.

I installed a Kenwood flip-out for my father and have all the external units hidden above the spare tire.

i dont have the specs as far as the box size i had them saved on a PM someone sent me about the same box but i have since then cleared my inbox. as DB to measure it up real quick for you!

Still never saw any numbers from this. And a few of us were interested.

No numbers yet because I traded a pair of SSD's for it the next morning and it is sitting in my jeep being ran @ 1000w until my other HDC3 15" gets here and my new amp. I'll be sure to get #'s and vids once I get it all setup in the Jeep.

I mean, I can always run out and put it on the TL the way it sits now, but it's probably only low 140's
