Equal-area cell partition of a CD exit under an imposed Hypex expansion — per-cell ducts routed to a coverage-defined mouth, exported as solids

The same throat partition routed into one vertical column of slots — path spread, vertical beamwidth and the HOM limits of cell and slot

Hypex family horn profiles — S(x) = St·(cosh(mx) + T·sinh(mx))²

Wall-primitive sectional area tool for square annular folded horns

Horn ↔ cone crossover — −6 dB coverage and DI step through crossover

Curved-mouth aperture arrays — wavefield, polars and beamwidth vs frequency by direct summation

Standing-wave pressure inside a rectangular enclosure — where a port entrance sees the modes that couple to the driver

Box Modes for any shape — load an STL of a speaker's air space and find where its standing waves press on the port entrance
