anyone got this or can direct me to it? my active crossover has died, and i've had to drag the old passive boards out of the closet. i thought i'd saved a copy of the circuit schematic, but apparently not, and the relevant page from the forum archives is dead. i can figure out gross but not fine points of connection orientation.

I was thinking about this design but had a questions. What did the effecency end up being.
And if I used real fullrange drivers would a tweeter still be neaded.

I believe it was still right at 96dB.
And if I used real fullrange drivers would a tweeter still be needed.
You would be starting from scratch.  The crossover posted above would be useless, the cabinet dimensions and tuning would change, etc. etc.  Generally speaking, a line array of full range drivers will almost always also require a tweeter.  (There are a few exceptions)
