Wayne, Would the Alpha 10 be usable in a transmission line? If there are curious audiophiles out there, and you can say there is at least a small chance of the alpha 10's working well in them, I might give it a try.
I have a TL that was designed for a 8" driver, but might be able to enlarge it for the Alpha 10 and try out. It is a 2 - tube design, 4 ft tall and a board down the middle on a angle separates the twin tubes(areas).
I also have a Radford TL with the larger area behind the driver, then exits down the back and folds a few times(can't see that part), and exits to the bottom of the front.
I could try these if you give a indication that it might work, or let me know what the downfalls to this would be. TL's generally have drivers with higher "Qts", and the Alpha 10 is sort of middle of the road.
What comments would you have on this!!!!!
