4. Setup and Installation
4.1 Mounting
The DC28F-8 tweeter is designed for flush mounting. Ensure the mounting surface is flat and rigid to prevent vibrations. A cutout diameter of approximately 2.875 inches (73 mm) is typically required, but always measure your specific unit before cutting.
- Carefully mark the desired mounting location.
- Cut the appropriate hole for the tweeter using a suitable tool.
- Drill pilot holes for the mounting screws.
- Secure the tweeter using appropriate screws, ensuring not to overtighten.
4.2 Wiring
Connect the tweeter to your audio system using high-quality speaker wire. Pay close attention to polarity: the positive (+) terminal on the tweeter should connect to the positive output of your amplifier/crossover, and the negative (-) terminal to the negative output.

- Strip a small amount of insulation from the ends of your speaker wire.
- Connect the positive wire to the red terminal and the negative wire to the black terminal on the tweeter.
- Ensure connections are secure to prevent intermittent sound or short circuits.
4.3 Crossover Integration
A passive or active crossover network is essential for protecting the tweeter from low-frequency signals and ensuring proper integration with other drivers in your system. The recommended crossover frequency for this tweeter is typically above 2 kHz (2000 Hz) with a 12 dB/octave slope or higher.
- Consult your crossover's manual for specific connection instructions.
- Ensure the crossover point is set appropriately to prevent damage to the tweeter from frequencies below its operational range.
5. Operating Principles
5.1 Audio System Integration
Once installed and wired correctly, the DC28F-8 tweeter will reproduce high-frequency audio signals as part of your complete speaker system. Proper system setup, including amplifier selection and crossover tuning, will significantly impact overall sound quality.
- Ensure your amplifier provides clean power within the tweeter's specified power handling.
- Adjust volume levels gradually to avoid sudden peaks that could damage the tweeter.
- For optimal sound staging, position tweeters to direct high frequencies towards the listening area.
6. Maintenance
The Dayton Audio DC28F-8 tweeter requires minimal maintenance. Follow these guidelines to ensure longevity:
- Cleaning: Gently wipe the mounting flange with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Do not touch the silk dome.
- Inspection: Periodically check wiring connections for tightness and inspect the tweeter for any visible damage.
- Environment: Keep the tweeter away from excessive moisture, direct sunlight, and extreme temperatures.
