3D CAD Model for Horn No.1155 —- Biradial for RAAL 7020XR
- Funds in CAD Currency
- Plastic throat adapter to ensure smooth horn flare transition
- 1.2kHz Fc
- 3D CAD Files can used for 3D printing or CNC Machining
- Support stand and rear foam
The below measurement is a comparison between the 1155 Horn (Green) and the driver mounted to a regular speaker baffle (Red).
The 1155 horn drastically improves the off-axis performance providing much wider coverage in the upper treble and also controlling the coverage in the midrange so that it matches the power response into the room. This drastically improves the natural sound of instruments giving them better musical timbrel accuracy. Edge diffraction is completely eliminated with the 1155 horn which improves transient detail.
