Product Information
Full details
The Citronic 10-inch coaxial driver (902.690UK) is designed for audio technicians and DIY speaker builders who need a reliable, high-performance replacement component for full-range PA cabinets and stage monitors. Its primary benefit is superior phase alignment due to the concentric design, which provides clear sound reproduction across a wide frequency spectrum; however, users should note that this is a raw component requiring a compatible enclosure and crossover knowledge for optimal installation.

FAQs
Is this driver suitable for a guitar cabinet?
While it can be used, this is a full-range PA driver designed for accurate reproduction; it may sound different from traditional dedicated guitar speakers.
Can I run this at 8 ohms?
No, this driver has a fixed impedance of 4 ohms. Using it with an amplifier that cannot handle 4-ohm loads may damage your hardware.
Do I need a separate crossover?
Yes, as a coaxial driver with both LF and HF components, it is recommended to use a high-quality crossover to ensure the frequencies are sent to the correct parts of the driver.
What is the mounting hole pattern diameter?
Please refer to your specific cabinet specifications to ensure the mounting holes align with the industry-standard steel frame dimensions of this 10-inch unit.
Is the tweeter replaceable?
The tweeter is integrated into the coaxial assembly; it is designed to be replaced as a single unit rather than serviced separately.
Troubleshooting
Distorted sound at high volumes
Check your amplifier settings and ensure the signal is not being clipped. Verify the crossover frequency to ensure the driver is not handling frequencies outside its range.
No high-frequency output
Inspect the internal crossover wiring to ensure the HF signal path is intact and the connection to the concentric tweeter is secure.
Rattling noise during playback
Ensure the driver is tightly mounted to the cabinet baffle and that the mesh dust cap is not loose or damaged.
Pros and Cons
Pros
- Excellent phase coherence due to the coaxial driver architecture
- High power handling suitable for professional PA and foldback applications
- Robust steel frame construction ensures long-term reliability
- Direct replacement compatibility for Citronic CM-series active units
Cons
- Requires technical knowledge for enclosure integration
- Raw driver component only; does not include external cabinet or grill
- Requires a compatible 4-ohm amplifier setup
Setup, Compatibility & Care
Installation requires basic soldering skills and knowledge of speaker wiring. As a 4-ohm driver, ensure that your amplifier is rated to handle this impedance load to avoid overheating or hardware damage.
- Wiring: Ensure positive and negative terminals are connected to the correct crossover outputs.
- Care: Avoid exposing the paper cone to moisture or direct sunlight for extended periods.
- Maintenance: Periodically check that the mounting bolts are secure to prevent unwanted vibrations and rattles during high-output sessions.
