Hi, I plan to build a new 3 way open baffle someday when I can afford all the pieces. However, for now, I would just like to make some quick temporary baffles for a pair of Eminence Beta 12 LTA's that should arrive here about Monday. I have been playing with The Edge program. So far I have gotten the smoothest simulation by making a 450mm x 700mm Oval shape with the driver either placed at the very bottom or the very top of the tall oval. I am new to this. One question I have about The Edge is why whenever you start a new simulation the mic distance always goes automatically to 100m? If I change the number to the distance I will be listening from (say 2 meters) the response does not look so good.
If I am doing the above equation right, it means my baffle should be at least 15.7 inches wide?
I am not much of a computer person. I would have liked to try the other free program mentioned in this thread. I was able to download it, but perhaps my computer is not set up to actually use the program, I don't know.
I would be greatfull for any suggestions or help. The specs for the Eminence Beta 12 LTA's are as follows:
Sd in sq cm 532.4
Effective diameter 12.0 inches, 305mm
Qts. 0.51
Fs 45Hz
Listening distance 2 to 3 meters
Any suggestions much appreciated
Sincerely,
Benjamin
