3-4 inch Tang Band in a TL

[fireman]

I just finished assembling a 1/4 wave TL sub for the living room. I still have a little tweaking to do but already I am very pleased with the result. !

But now I have more and more reserve with my old Toshiba speakers. As a matter of fact, they sound like crap. They have absolutely no highs, the mids are not bad but not exactly lively and the bass is terrible.

The sub has definitely helped a lot with it's tight bass. Now I need something that can replace the Toshibas. I remember first looking at Rob Sampson's web site and finding the concept quite interesting. Unfortunately, I have no clues how to do the calculations to achieve such a project.

My goal would be to use a 3-4 inch Tang Band friver in a configuration that might look something like the Boomtube.

Is this possible ? If so, could someone point me in the right direction in order to find the calculations required to achieve such a design ?

Simple sealed boxes are all you need to integrate with the sub.

If you like the Tangband drivers (as I do, especially the W3-871S) I would suggest the following.

For a single driver application see:

For two driver applications see:

or

For a four driver application see:

I know that many have built Voigt pipes using RS 40-1197s and Fostex FE-103s and that the Tangband W3-871S should be able to work in something similar although I've not actually tried it.
