Title: straight 8 crossover v3 schematic
Post by: khingila on December 15, 2014, 12:15:15 PM

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.

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)
