Hi Wayne,I am building the 18 Pi, but using corner-placed BR-cabinet for the Magnum 18HO.
Did you modify in between the cornerspeaker crossover, like you did for the 4 PI? You send me the plans for my speakers in March 2006.
If you have modified the crossover for the Cornerhorns, please send me
the changes.
Thank you and have a nice Day
Karl
