The four π loudspeakers is a hifi speaker. Its drivers and crossover are robust enough it can be used for prosound but it is not suitable for arraying. The only exception is pairs - You can put one speaker on top of another with tweeters together to form an MTTM arrangement.
The thing I think you're looking for is an arrayable speaker that can be flown. Something with a vertical row of midwoofers and a vertical row of tweeters. One cabinet that holds one woofer and two tweeters, designed to be connected together and hung in a vertical array.
This could certainly be built in a configuration very much like the four π speaker but it would require a complete design/test/optimize lifecycle and unfortunately, we do not have plans to do anything like that at this time.
However, if you are willing to do some testing, I can help guide you through the process. That's what AudioRoundTable.com is here for. So if you do build an arrayable speaker like this, please keep us posted.
