This Windows-based program calculates the theoretical acoustical impedance, SPL response, electrical impedance, diaphragm displacement, phase response and group delay versus frequency characteristics of finite and infinite horn loaded loudspeakers.

Finite horns radiating into free space, half space, quarter space or eighth space can be analysed (4 x Pi, 2 x Pi, Pi or Pi / 2 steradians solid angle).

Horn systems can have an oblate spheroidal waveguide, a single Le Cléac'h, tractrix, spherical wave or Salmon's family hyperbolic-exponential flare segment, or up to four conical and/or exponential flare segments connected in series, coupled to a throat chamber, loudspeaker driver and acoustically lined or vented rear chamber.  Horns with multiple drivers and arrays of multiple loudspeakers can be modelled.
