Danny, a related question.

Given two 4 ohm woofers rated at 89 DB @ 2.83v efficiency are hooked up in series yielding a nominal 8 ohm load and an 8 ohm tweeter rated at 89 DB @2.83v efficiency, using a standard first order crossover, what would the relative efficiency between the woofer and tweeter section be?

Would the woofer section and tweeter both produce 89 DB? (at 2.83v)
