as long as you have a nice blade it cuts good, but i would like to have a larger table on top, because when cutting larger pieces it starts to become a pain.

its aported box with a huge port and its long to maintain the tuning
this is wat a 1/4 wave box looks like...http://en.wikipedia.org/wiki/Image:TransmissionLineSpeaker.png
if u notice how some of the wood is slanted and at the end of the box its just an opening..

other than that....beautiful fuc.kin box...u have good wood working stills

However, a TL does not need to be tapered.

iirc the port opening area of a T-Line enclosure matches the Sd of the woofer. so depending on how big the vent/box starts out at some ports are tapered down to size.

From what I understand, t-lines can either taper down from the mouth, taper down to the mouth, or be the same throughout.... though I've never designed one myself, this is just from the reading I've done so far

they are used to keep the port a more constant width, but work great for structural integrity:)

It doesn't really matter if you guys think it isn't a "true" TL, that's how it'll perform, just try and model it as a ported box and see how far you get.

Yep, but not all are.

From what I understand, t-lines can either taper down from the mouth, taper down to the mouth, or be the same throughout.... though I've never designed one myself, this is just from the reading I've done so farRight. They don't actually have to taper, but the point of the enclosure is to slow the rear wave down significantly so that it goes from completely out of phase to back in phase with the front wave by the time it emerges. Usually you fill it with some form of batting to slow it down even further, although you don't have to if it's long enough. JBL's enclosure here does not appear to be a true TL, but a ported enclosure without a pressure chamber. It should work around the same way, however.
