HiFi Vector Adapter spacer ring for American Bass XFL 15" 2025 model Subwoofer
 
 
This is a custom made 3D printed adapter ring to use with the 2025 model American Bass XFL 15" subwoofer. This subwoofer has a larger mounting hole and will NOT fit into a 13.6"to 14" standard cutout. This adapter makes it fit into the smaller box hole without cutting your box.
 
 Check out our 2025 American Bass XFL video on Youtube to see the spacer being used.
 
Make sure your 15" XFL is like the one in the picture.
