Need TL plans
I'm planning on using the Pioneer 8" full range driver from Partsexpress and was interested in some TL plans. Can anybody lead me in the right direction?? I don't know how to find line length and all that, so that's why I really want some plans.

Hi, try this site

I have been using Martins calculation for a while now and the results are remarkable. Regards :cool: 
Yeah, I've been there but I'm still confused on where to start. I just need some plans. I found some for a BIB transmission line for the Pioneer driver but I don't know how to start it out. The height and width will be 10" x 20" ( the Sm is 200 square inches so I just went with 10" x 20") I just don't know how tall to make the enclosure though:bawling: The line length is 138"

Hi... "The line length is 138"
Imagine the BIB without the center baffle. Just a tall tapered ‘triangular shape’… the BIB is basically this ‘triangular shape’ folded in half. http://www.zillaspeak.com/bibhowtobuild.asp In the case of the PioneerB20, the line length is 138 inches. That means the total length of the cabinet unfolded is 138”… by folding it in half you still have a line length of 138” but the actual cabinet inner dims is half, or 69 inches. You simply halve the line length. Does that make sense? Godzilla PS. Yeah 69! 
Yeah, I got it all sketched up, L=138". Center of speaker 30" down from the top of the enclosure. The thing is, I didn't know if was supposed to make the inside board 69" long. It makes sense now that I think about it. So now the box will be around 79" tall if the inside piece is 10" from the bottom of the enclosure (a=b=c=depth/2) But is it okay that the width and depth is 10"x20"?

No inside board 69" long, but inside height of enclosure is 69".
Total height of enclosure will be 69" + baseplate thickness. Inside depth of enclosure D= sqrt(Sm*sqrt(2)) + inside board thickness Inside width of enclosure W= Sm/D or D=sqrt(2)*W = 1.41*W 

argh, so what exactly should the dimensions of my TL be then? I'll figure it out, I just want to know exactly. So someone smarter than I, please chime in :D

visit http://www.zillaspeak.com/bibhowtobuild.asp  there's enough and more information there.

yeah, that's where I got my plans from but it doesnt tell you how tall to make it, unless I'm missing something.
