Did you read the OP? Are you even thinking about design?

The design of the Vandersteen (and Thiel and Dunlavy) speakers is multiple phase-coherent drivers mounted in a time coherent manner (such that the sound from each driver arrives at approximately the same time), using relatively simple crossover systems, mounted on relatively small baffles (except the Dunlavy).

Obviously not your cup of tea, but a nice, simple design nonetheless.
