Horn Adapter 100 mm 34 mm Thread
This black ABS adapter connects a horn to a tweeter speaker by converting the mounting interface. It is built for home-theater, sound-bar and DJ-system installations where the driver and horn have mismatched bolt patterns. The single-piece design means no extra hardware is required beyond the adapter itself. Buyers who need a packaged kit with screws or gaskets should look elsewhere.
Installation Ease and Common Issues
The adapter screws directly onto the horn using the 34 mm thread and aligns to the tweeter through bolt-circle holes spaced between 51 mm and 87 mm. Long-distance holes give some lateral adjustment so minor misalignment can be corrected by hand. The only frequent issue is discovering that the existing horn flange falls outside the 51–87 mm range, which makes the part unusable without custom drilling.
Critical Fit Specification
The bolt-circle diameter range of 51 mm to 87 mm is the single measurement that decides compatibility. If the tweeter mounting holes sit inside that window the adapter will bridge the 100 mm outer horn flange and the 34 mm thread cleanly. Outside that window the holes will not line up and the adapter cannot be used.

The adapter mates when the 34 mm thread engages fully and the bolt circle aligns between 51 mm and 87 mm.
What does the package contain and what extra parts are needed?
The box includes one black ABS horn adapter only; mounting screws and any horn or tweeter units must be sourced separately.
Which version should I choose for a 100 mm outer-diameter horn?
This single model has a 100 mm outer diameter, 34 mm thread and adjustable 51-87 mm bolt circle, covering that size directly.
