to even out the front of the box.

What kind of mounting depth are you looking at for that speaker??

JBLCAMRY

the box allows for a max of 9 3/4" , and the Mj is 8"

just looks like normal vented box. with a longer port..

JBLCAMRY

looks very nice.

how do you like that craftsman table saw? im really thinking about picking one up but some customers say they have had problems with the cheaper models and others say they work great.

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.

just wait till you see it when its done, the motor is being rebuilt at the moment (454 bored out to a 461, all race parts= 800+hp)

my thoughts exactly

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

JBLCAMRY

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

ZOMG, not a T-line here either. Just a box with a really large external port :rolleyes:

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.
