Do the tml's exit at top and bottom? I like how each driver excites a different position in line, I have wanted to put two drivers along same line but was warned that there may be cancellation effects. Is this not a problem? I love the Viva TC9FD by the way - awesome driver for many applications.

Yes exactly.
This will be an aperiodic vented labyrinth.
It's not designed to be a quarter way resonator.
Do you mean cancellation between drivers as in lobing and comb filtering?
If so, it's been covered earlier in this thread.
Yes, the tc9 is great! It might just be the best value in audio....well, next to lamp cord

No, I meant cancellation as in the quarter wave bass portion on the backside. How do you design an aperiodic vented labrynth if there is no 1/4 wave distance to calculate? I am not familiar with it.

Well, aperiodic means without period.
The line will be stuffed to max capacity, with the vents on the top a bottom.
This is to insure the back wave will not return to the drivers.....(or as little as possible)
What will come out of the vents will be so attenuated and low in frequency that there should be no cancellation or reinforcement with the front wave.
Especially when I'm not going to boost the low end. The low end BW will be the Fb of the drivers, around 150Hz or so. (I'm using stereo subs).

Thanx brother!
It's not too hard to build. The only hard part is keeping the cuts perfect. If you are even 1/2 a millimeter off, it's screwed because of the length of the cuts.
I have to wait for a week to cap the ends....I didn't have enough foam so it's being shipped to me

Cannibalize some old pillows like I did. Do you have to use foam vs polyester fill?
