10" Subwoofer Speaker Spacers - 1/2" Thick PVC Depth Extender Rings

These subwoofer spacers are an absolute lifesaver when you're trying to install aftermarket speakers that are deeper than your original equipment. The 10-inch size with 9-1/8 inch inner diameter and 10-7/8 inch outer diameter fits most standard subwoofer applications perfectly. What makes these stand out is the PVC construction - unlike MDF or wood spacers that can rot or warp over time, these PVC rings are practically indestructible and resistant to moisture damage. The 1/2 inch thickness gives you decent clearance, but the real genius is that they're stackable - you can use two or more together if you need even more depth for those massive subwoofers. Made right here in the USA with CNC machining, the quality is consistently precise with clean edges and perfect circles. I've used them for car audio installations where the new subs were just a bit too deep for the factory locations, and they provided the exact spacing needed without compromising sound quality. The material is dense enough to prevent resonance or vibration issues. Installation is straightforward - just place the spacer between your speaker and mounting surface, and use longer screws to secure everything. Whether you're upgrading your car audio system, building custom enclosures, or need to adapt speakers to non-standard openings, these spacers make the installation clean and professional-looking. They're particularly useful for fiberglass enclosure work where you need precise framing. For the price, they deliver professional results that make aftermarket speaker installations so much easier.
