4. Installation
The DS18 PRO-HP52/BK horn waveguide is designed for easy bolt-on installation with compatible compression drivers. Ensure that the compression driver you intend to use has a 2-inch throat and a matching bolt pattern.
- Prepare the Driver: Ensure your compression driver is clean and free of debris.
- Align the Horn: Carefully align the bolt holes on the PRO-HP52/BK horn with the corresponding bolt pattern on your compression driver. The horn features a driver bolt pattern of 4.05 inches (102mm) x 4-0.26 inches (6.8mm).
- Secure the Connection: Use the provided bolts (or appropriate hardware for your driver) to securely fasten the horn to the compression driver. Tighten the bolts evenly to prevent damage and ensure a proper seal.
- Mounting: Once the horn is attached to the driver, mount the assembly into your desired location. The horn's mounting bolt pattern is 6.3 inches (161mm) x 4-0.21 inches (5.5mm), and the mounting hole diameter is 5.43 inches (138mm).

5. Operating Instructions
The DS18 PRO-HP52/BK is a passive horn waveguide and does not require specific operating instructions beyond proper installation. Its function is to direct and amplify the sound produced by a connected compression driver.
- Ensure the compression driver connected to the horn is properly wired to an appropriate amplifier.
- Refer to the instruction manual of your specific compression driver and amplifier for their operating parameters and recommended settings.
- Always operate your audio system within the recommended power handling limits of all components to prevent damage.
6. Maintenance
Regular maintenance will help preserve the appearance and performance of your DS18 PRO-HP52/BK horn waveguide.
- Cleaning: Use a soft, damp cloth to wipe down the horn. Avoid abrasive cleaners or solvents, as these can damage the plastic and chrome finish.
- Inspection: Periodically inspect the horn for any signs of physical damage, cracks, or loose connections. Ensure all mounting bolts remain tight.
- UV Exposure: While the horn is UV resistant, prolonged and extreme exposure to direct sunlight can still affect its longevity and finish. Consider protective measures if the horn is installed in an area with constant direct sun exposure.
7. Troubleshooting
As a passive component, troubleshooting for the horn waveguide is generally limited to installation and physical integrity.
- No Sound or Distorted Sound: This issue is typically related to the connected compression driver or amplifier. Verify that the compression driver is correctly installed and wired, and that the amplifier is functioning properly. Check all connections for tightness and proper polarity.
- Loose Horn: If the horn feels loose or vibrates excessively, re-tighten the bolts securing it to the compression driver and the mounting surface. Do not overtighten.
- Physical Damage: If the horn is physically damaged (e.g., cracked, broken), it may affect sound quality and should be replaced.
