Two beveled PVC spacer rings with a 148 mm mounting hole and tapered 38 mm to 19 mm depth position 6.5 in speakers for clearer sound projection
This 2-pack of beveled spacer rings fits most aftermarket and OEM 6-1/2 speakers. Each ring has a 148mm mounting hole diameter and is moulded from moisture-resistant PVC. The set suits car, marine and custom audio installs where factory depth is insufficient.
The beveled profile tapers from 38mm to 19mm, directing sound toward listeners while clearing door panels and window tracks. Builds that require flat-mount rings, larger diameters or metal construction will not match this design.
Rings press into the existing speaker cut-out and accept standard 6.5in screw patterns; no adhesives or special tools are required. Mis-aligned bolt holes or over-tightened screws can crack the PVC, and uneven door metal may leave gaps that let water in.

The rings have a 148mm mounting hole diameter designed for most aftermarket and OEM 6-1/2 speakers.
The beveled profile tapers from 38mm down to 19mm, angled to avoid interference with door panels and window mechanisms.
The speaker should mount flush against the beveled surface with no gaps, and the cone must move freely without contacting the door panel or window track.
