One of the problems with horns is the inflexibility of frequency cut-off: you are limited to a discrete number equal to the number of horns you have. This makes experimentation difficult without having an absurdly large array of different horn sizes to try. So how about the following configuration:
The entire loudspeaker is a single profile that changes continuously in cross section from floor to ceiling with high frequencies being in the centre and low at the extremes. Any cut-off frequency is therefore always available (in two positions): it is simply a matter of driver positioning. Equally, the only limit on the number of "horns" is the number of drivers. Removable horizontal septations can be introduced if necessary but it would be nice to do without them.
Once the optimal profile is determined the thing would be trivial to build: it could be just a series of CNC'd slabs of mdf stacked on top of each other.
