Sample Waveguide - ST260

Type: Free standing, axisymmetric rolled-back
Dimensions: ⌀260 mm x 83 mm / 1" throat (19° opening angle)

Available STEP and STL files | ABEC Project

Note: The profile is not part of the CE series. This is a freely available predecessor with a somewhat higher DI. The smoothness of the acoustic response is nevertheless very similar.
