Any reasons not to go 4th order LW when going all active crossovers?

[MarkB1]

I am thinking of tri amping with Seas Millenium, Seas W15 and Seas W26. With my limited knowledge, it seems like a good idea to use 24 db LW crossovers, mainly due to the fact that it would help avoid the peaks of the excel drivers.

Any reason why this would not be a good idea? All the info I can find seems to suggest that it would be the best option, but I am aware that some high end speakers use different slopes including 1st order crossovers in certain situations. I assume that this is because of the phase charactoristics, and it not being fesable to use 24db passively.

Any help is greatly appreciated.

Do it, it's good. Just make sure you either take the responses of the drivers into account when designing the crossover, or make the crossover points an aboslute minimum of an octave away from resonance.
