The electro-mechanical parameters of the Alpha and Delta drivers is different but the average broadband efficiency is nearly the same. There is a slight padding difference between models, but not very much. The peaks up high are due to breakup modes and you should crossover lower than that. If you'll crossover below 2kHz, you will not have the peaks from breakup modes.
