3D Printed Rear Cover No.2376 for SB Audience 65CDN-T

05/07/2025: We've updated the design to allow easier printing. We've eliminated the need for supports. This creates a better surface to seal against the compression driver. 

Old Design (REV00)

This product is the 3D printed part that I designed specifically for the SB Audience 65CDN-T compression driver.  This cover will also work for the ceramic version (65CD-T).
