6.75-inch Universal Custom Made Speaker Adapters
Are you looking to add speakers to a custom project or add additional mid-bass speakers to a new location?

If so, our custom made speaker adapters are a perfect fit! These adapters are made in-house out of premium expanded polyvinyl chloride (PVC) or high-density polyethylene to ensure a solid platform for your new speakers.

We also include some universal mounting hardware along with an MDF ring to allow easy tracing to cut the hole out of your material.

Common uses for these adapters are for audiophile-grade mid-bass installations, pro-audio style drivers (PRV, Beyma, Ground Zero, DD Audio, etc) or even mounting of subwoofers in an infinite baffle application.

We offer these rings in virtually every size and can build custom rings if needed. Contact us with any questions you may have.
