Replaces factory speaker spacers on fairing-based HD motorcycles. Contoured reduction shaping allows for a smoother sound transition to the factory speaker opening without narrow platform step mounting like other speaker rings. Smooth funnel reduction shaping prevents speaker from resting on sharp edges, reduces potential frequency cancellation, and improves overall output of new larger speakers.
• Higher performance
• Allows for 6.5″ speakers in place of factory 5 1/4″ speakers w/out mod
• Increase mid bass response (speakers sold separately)
