This speaker terminal cup is designed for installation into subwoofer enclosures or speaker boxes to provide a clean connection point for your audio cables. It features two binding posts for positive and negative terminals, housed within a black plastic casing that allows for a recessed, flush mount against the cabinet surface. To secure the unit in place, you can use the four integrated screw holes, which ensure a stable fit during use. This component is a practical choice for anyone building or repairing their own sound system who needs a simple and reliable way to route wiring from the outside of the box to the internal driver.
