Customer Reviews (4.8 / 5 · 5 reviews)

Edward ★★★★★

The twist-lock mechanism clicked into place perfectly on my first attempt, saving me from having to wrestle with screws. Sound is noticeably cleaner now that the midrange is properly isolated from the door panel vibrations.

Sofia F. ★★★★★

The twist-lock mounting system was dead simple to install—took less time than I expected. Really glad these rings let me swap in the 4-inch midrange without any cutting or drilling.

Grace U. ★★★★★

The adapter rings fit perfectly into the factory cutouts, making installation take less than ten minutes. Sound clarity improved noticeably even at higher volumes, and the locking mechanism feels rock-solid once twisted into place.
