Default Active crossover from scratch.

I want to build an active crossover to go between a dayton rs hifi sub and an altec model 288c horn speaker at 500 hz.
I will also have to attenuate the horn from the 115db efficiency to the 89db of the woofer. I suppose a higher order crossover would be best because of the differences of the two speakers. An active crossover needs to be powered, how do i know what voltage to supply?
