Create a neat and accessible connection point on a compatible speaker enclosure with the TFF Round Speaker Box Terminal Cup.

The round recessed housing features two gold-coloured binding-post connectors for positive and negative speaker connections. Red and black polarity indicators help identify the correct terminals, while the recessed design helps protect the connectors from accidental contact.

Four mounting holes allow the terminal cup to be secured to a suitable speaker cabinet or subwoofer enclosure. On the rear, two gold-coloured connection tabs provide attachment points for the internal speaker wires.
