THESE SPEAKER SPACERS ARE MADE FOR MOST 6.5" SPEAKERS!
NOT ALL 6.5" SPEAKERS!
SOME 6.5" SPEAKERS HAVE A LARGE MOUNTING DIAMETER, ESPECIALLY INEXPENSIVE SPEAKERS OR REALLY EXPENSIVE SPEAKERS! HOWEVER, THESE ADAPTERS ARE MADE FOR 6.5" THAT HAVE A 5" MOUNTING DIAMETER!
WE DO NOT, NOR HAVE WE EVER, MADE A LOWER FAIRING SPEAKER ADAPTER FOR ANY SIZE SPEAKER OTHER THAN FOR A 6.5" SPEAKER! NO, THESE ARE NOT FOR 5.25" SPEAKER. 5.25" SPEAKERS REQUIRE A 4" HOLE! (JUST SAYIN)
