I have a wonderful basshorn available - the 12π basshorn subwoofer. It is available as a completed cabinet, as a flat pack kit or a driver kit. I can send plans if you're interested.
The matching 9π top box is conceptually designed but not ready for sending plans out yet. My progress on new projects is very slow because I have a lot of other responsibilities right now that keep new loudspeaker development at a snail's pace. You can take the 9π concept and implement it easily though since it is just three straight horns.
Thanks you Wayne, for the concept pertaining to the top for basshorn subwoofer.I awaits your plan when it's available,in the meantime i will accept the plans for the basshorn.
Thanks for well needed information. I plan yo try and try and implement a 9Pi top, can i get a side elevation sketch, so that i can understand more, the horn placement concept?

Each horn is to be independent of each other. This makes them more configurable for the installer. The challenge is how to make them most configurable and at the same time make them easy to setup in a building block approach. For example, with the cabinets in the shape of a truncated pyramid, they are easily splayed but they don't sit nicely on top of one another. The solution is external hardware brackets, which allow multiple placements to be possible. That's where I'm at with the design. Conceptually, it is three indepedent horns having cabinets shaped like truncated pyramids with brackets that are adjustable to allow them to sit one on top of each other or to be arrayed in groups.

Sure, passive line level crossovers could be used. If you think about it, analog active filters are generally just passive components surrounded by active buffer stages. So a passive line level crossover is not much different than an analog active crossover.
On the other hand, the basshorn is long enough that some delay for the mains is in order. The midrage and tweeter horns are about the same length, but the midbass horn is longer. Appropriate delays for each subsystem could be done with position, but electronic delay lines are probably more convenient. This makes more sophisticated crossovers somewhat attractive.
