• Precision-machined horn flare adapter designed to connect 1-inch screw-on compression drivers to bolt-on style horn throats.
• Features standard 1-3/8" - 18 TPI male threaded neck to accept threaded high-frequency compression drivers.
• Constructed with a heavy-duty die-cast metal body to eliminate acoustic resonance and ensure structural rigidity under heavy driver mass.
• Features a smooth 1-inch (25.4mm) internal throat taper to maintain seamless acoustic transfer and prevent internal standing waves.
• Ideal for sound engineers, cabinet builders, and repair technicians adapting mismatched compression drivers and horn flares in PA speaker systems.

Features

• Threaded-to-Flange Conversion: Adapts 1-3/8" threaded compression drivers to fit standard 2-bolt or 4-bolt horn flare patterns.
• Acoustically Tuned Taper: Smooth internal expansion profile preserves high-frequency dispersion and minimizes air turbulence.
• Heavy-Duty Die-Cast Construction: Durable metal casing supports heavy high-frequency drivers without flexing or cracking.
• Multi-Pattern Mounting Flange: Features pre-drilled mounting holes compatible with standard 2-bolt and 4-bolt horn patterns.
• Compact Footprint: Low-profile depth minimizes physical displacement behind horn flares inside speaker cabinets.
