A nice looking box, but which 6in driver in particular? Since like any other vented alignment the box tuning & volume of a QW pipe need to be appropriate for / designed for the intended drive unit's requirements, it would be useful to know which you had in mind.

Many 6in or 5in drivers can be used and tuning response with damping material.
This box is idea for test TQWT and I will share project with crossover.

Very possibly, but in what general region of Q and Vas for the alignment you anticipate / intend?

Indeed! A TQWP as shown would want a fairly low Q driver. A high Q driver would need an entirely different folding to place the driver nearer to the closed end. Finally, the overall volume of the pipe would depend on the Vas of the driver, which is all over the place in available 5-6" drivers.

I intended to use VISATON AL130

AH! OK.

My first impression looking at the T/S parameters is that a Qts of 0.38 may be a little high for a TQWP, but probably doable. The Vas of 13l, though is going to produce quite a challenge making the passages small enough.

Good luck!
Bob

I think that the AL130 driver would work well in MLTL.

Thanks, AL130 is from old T line box and I like this box size for small room.
