Precision Dimensions for Easy Installation
Each terminal cup measures 56.5mm in overall diameter with a required cutout of 50mm. The mounting depth is 30mm, fitting most standard MDF or plywood enclosure thicknesses. Four corner screw holes (countersunk for flush mounting) ensure a secure, airtight seal that prevents air leaks and cabinet resonance. Installation is simple:
Mark and cut a 50mm square hole in your speaker cabinet
Insert the terminal cup from the outside
Secure with four screws (included) through the corner holes
Connect internal wiring to the rear terminals
