Daniel U. ★★★★★

Took maybe five minutes to twist the adaptor ring into place, and my 4-inch midrange now fits rock solid with zero rattles. The one-turn mounting system is exactly as simple as described, which made a finicky job almost fun.

Richard ★★★★★

Installed these adaptors in my BMW and the fit was absolutely perfect with that single turn locking system. The midrange now sits flush and secure, no rattling even at higher volumes.

Matthew ★★★★★

Took me maybe ten minutes to swap out the factory midrange in my Mini, and the ring turned smoothly with no forcing. The fit is spot-on for the 4-inch driver, so there’s zero rattling even on bumpy roads.
