Product Overview
Make room for a large-basket 10-inch subwoofer or midbass driver in the shock-bump location of a compatible Harley-Davidson saddlebag. Nagy’s Customs Monster-Mega adapter rings are designed for 1998–present models and accommodate driver bolt patterns larger than 9.4 inches.
Use this pair when a standard adapter ring will not suit your driver’s basket and bolt pattern. The rings are intended for saddlebag installations, with fitting work sometimes needed to suit the bag.

Why Choose This Product?
These Monster-Mega rings address a specific fitment need: large-basket 10-inch drivers that do not fit standard adapter rings. Their 9.40-inch mounting diameter and larger-bolt-pattern design help avoid removing gaskets, trimming the speaker basket, or forcing a fit.
They are not intended for a 9-inch basket subwoofer or midbass driver. Choosing by the driver’s basket and bolt pattern helps you determine whether this oversized ring is the right option.
Installation & Compatibility Notes
- Check the driver: Confirm it is a large-basket 10-inch driver with a bolt pattern larger than 9.4 inches. These rings will not fit a 9-inch basket.
- Plan the bag fit: Some fitting may be required depending on the saddlebag manufacturer. Minor sanding or silicone caulk may be needed to address small gaps.
- Secure the installation: A two-part epoxy, such as 3M 08115, is recommended for bonding the adapter to the saddlebag.
- Allow for separate inserts: Mounting screws are included, but threaded inserts must be purchased separately if needed.
- Consider the work involved: Installation requires cutting the saddlebag, and some knowledge of bodywork is recommended. OEM stock bags or quality aftermarket bags are noted as the easiest options.
