My T-line and halfa$$ explination for those who were asking about it.

couldn't think of the exact work before but it velocity, it changes the velocity of the air,

his a cut from t-section in sticky

Here is the Sketchup schematic in 3D

Those 7"x7" blocks on each side are used for measuring, so the middle divider goes in straight, and if you want to get technical, they assist in compressing the air together while entering the line

Those side blocks would be fun to experiment by adding more to tighten the throat, to change velocity, you will change the tightness of sound, and even adjusts excursion, you can literally watch excursion change while tightening the throat up

But, lets just say they are there to keep the line divider straight, don't get confused

arent you supposed to have the speakers vertical, not horizontal? because the one closer to the port is "farther away" internally than the other one.

like side by side instead of front and back?

[locomanny569]

nice!

Just keep the power low and you'll be fine

How low is low?
