Horn No.1887 ES-600 Biradial for TAD TD-4001
By purchasing these plans you will automatically receive via email the 3D CAD file required to CNC machine or 3D print the horn for DIY purposes.
Based on the popular ES-600 Biradial, horn No.1887 is specially matched to the TAD TD-4001 compression driver which uses a 49.20mm (1.937") diameter throat.
The rear of the horn extends to provide a platform for a super tweeter. We recommend the Fostex T96A. We've optimized the location of the platform so that tweeter is physically time aligned with the TAD diaphragm. Additionally, driver center to center spacing is as close as possible which improves coherency.
