pro audio horn 3d model

Create a highly detailed professional midrange horn waveguide for pro audio applications. The horn must be designed for an 8-inch midrange compression chamber throat input and expand smoothly into a rectangular mouth output measuring exactly 470 mm wide by 350 mm high. Coverage pattern target: - 60 degrees horizontal - 50 degrees vertical The horn geometry must maintain controlled directivity with a smooth continuous flare. The internal expansion must be progressive and acoustically optimized, avoiding sharp transitions or diffraction edges. Design requirements: - Smooth round-to-rectangular transition - Large smooth internal curves - Constant directivity inspired geometry - No sudden area expansion - No decorative shapes inside acoustic path - Symmetrical horizontal and vertical profile - Thick rigid outer walls for 3D printing - Professional touring speaker aesthetic - Functional engineering style - Optimized for PETG or ASA large format 3D printing - Modular segmented design for
