Hi wayne,after my 1 st project using pi align on my beta lt, i have more confidence and knowing that the quality of the Pi, i have just bought a pair of delta 15 and the psd 2002 but for the horn i might use a wooden horn. i wonder if you could help me out with the crossover, i would be much thankful if you could e mail me the schematic for the xover for the 4 pi.
