Can you explain a little about how the crossovers overlap each other on the middle speaker(s)

what are your thoughts on crossover frequencies for these drivers in an arrangment like this.

I should have some finished pics of this monster soon. I was thinking of putting these cabinets on wheels, backloading the cabinet with a gas generater to power the amp. play some rap music and propel myself around town! reminds me of bar stool races.......

Secondly, but just as importantly, in my opinion, is the directivity performance and the behaviors that arise when there are multiple sound sources. These include the collapsing directivity of direct radiators and some horns, the loss of pattern control at low frequency of horns, and the nulls that form off-axis in the same line that drivers are stacked. For example, the matched-directory two-way concept is to crossover to the tweeter horn at the frequency where the directivity of the direct radiating midwoofer collapses to the point where it matches the horizontal pattern of the horn. At the same time, the vertical spacing is set so the vertical nulls are just outside the horn's vertical pattern.

Thirdly, where possible, consider the enviroinment the speakers will be used in. Speakers with controlled directivity do this to some degree by limiting early reflections. But if the speaker is placed in stands a few feet above the ground, then self-interference from the floor reflection will cause a notch in the upper bass or lower midrange. By placing the woofer lower to the ground, this can be avoided. A midrange that is placed higher, which would otherwise suffer from a floor bounce notch, can be covered by overlapping the range with the woofer. The distribution of sound sources this way will cover the notch and prevent it from occuring.

Thanks for the suggestions! Lots to think about there. I think I can experiement and dial it in with an active setup. Making it easier in the long run. In an effort to conserve an amp and being able to use a 3way crossover. (not having to get another to make a pair of 4ways) What would be any draw back from using a passive crossover between the 2426 and the 2405? If so, would 2nd order be ok? or out of place with 4th order from the active unit.

just thinking outloud. as usual there are a lot of options so I'm just tossing around a few ideas. What would work nice is one multi channel amp so I dont end up with a rack in my living room. 6 channel amps are popular, 8 channel there are a few but not as popular. Perhaps a 6 channel and continue to use the plate amps for low frequency power. This isnt a tremendous issue yet since I'm still short a pair of 2405's. tweeters outside the box!
