Here is my proposal for an ideal horn system. The concept derives from the really of the horns as I know them, the available park of the drivers, the drivers’ real capacity and from… everything else that I might comment upon if you would not figure out where I was coming from…

110dB multi-channel installation, multi-amping with identical two-stages SET amplifiers, with each amp optimized for own channel. Here are the channel from top to bottom

1) HF channel. A120dB-sensitive hemispheric array of compression drivers, with a dispersion approximately 180° x 230°, sitting deep in the transition slop. First order high-pass.
2) Upper MF channel. A soft magnet compression driver with severely meticulous phase plug, taking out of the driver all that it’s 2’-4’ would be able to give. Response from 13K to 1.2K. First order high-pass. 550Hz spherical horn.
3) Lower MF channel. A soft magnet driver with no phase plug. Response from 150Hz to 1.2K. First order band-pass. 120 Hz spherical horn.
4) Upper bass channel.  A single driver of Fs 40Hz loaded into 45Hz horn. Response, floor coupled, - 45Hz to 150Hz. Diagonal horn spreading.
5) LF channel. A line array of the entire room height with individually sealed enclosures featuring 18” underhand with Fs of 11Hz. The array should be positioned outside the upper bass channel.

Interestingly that having a sufficient amount of space (many of lofts that I have seen or juts the homes/apartments with open floors layout) to position such an installation alight the horn naturally would not be a big deal.

As the shortcoming of this I can see only size and space. Also, it is not clear what amplification might be used for bass channel.  If it were a tube amp, then should be a SET and to use the same driver and the same linestage coupling principle as the rest amps but it might use a different output tube stage.  For instance some of those high voltages transmission tubes with 400-500W plate dissipation. With 2-4 drivers of 99dB sensitivity 200W of SET power should be enough to drive the LF channel in the room of that size.
