Product Information
Full details
This 12-inch, 8-ohm woofer driver is designed for users needing robust low-frequency reproduction in full-range PA systems. Its key benefit is high power handling for efficient delivery of deep bass. A potential caveat is its specific impedance requirement of 8 Ohms, which must match your system's configuration. Key features include a reinforced paper cone, a sturdy steel frame, and a broad frequency response suitable for demanding audio applications.

FAQs
What is the impedance of this woofer driver?
This Citronic woofer driver has an impedance of 8 Ohms.
What is the power handling capacity?
The driver can handle 300W RMS (Root Mean Square) power.
What frequency range does this driver cover?
It covers a frequency range from 50Hz to 3kHz.
Can this driver be used for home stereo systems?
While it can be used, it's primarily designed for PA systems. Its frequency range and power handling are optimized for professional audio applications, and it would likely need specific integration into a home system.
Do I need a crossover with this driver?
If used in a multi-way speaker system (like a typical PA cabinet with a tweeter), a crossover is essential to direct the appropriate frequencies to this woofer and prevent damage from high frequencies.
What are the physical dimensions?
The dimensions are a depth of 160mm and a diameter of 310mm.
What is the sensitivity rating?
The sensitivity is rated at 96dB, indicating good efficiency in converting power to sound.
What is the weight of the driver?
The driver weighs 4.8kg.
Troubleshooting
No sound output from the driver
Check all wiring connections for looseness or incorrect polarity. Ensure the amplifier or system is powered on and outputting a signal. Verify the driver's impedance (8 Ohms) is compatible with the amplifier's minimum load rating.
Distorted or rattling sound
Reduce the input signal level. Check for obstructions around the voice coil or cone. Ensure the driver is securely mounted to the enclosure and that the enclosure itself is rigid and well-braced. Verify the audio signal is not clipping.
Reduced bass output
Confirm correct wiring polarity. Ensure the speaker enclosure is properly sealed to prevent air leaks. Check that the driver is being fed appropriate low-frequency signals, possibly via a crossover, and that the amplifier is providing sufficient power.
Driver overheating or smelling of burning
Immediately disconnect power. The driver may be overloaded or receiving a signal that is too powerful. Verify the RMS power handling (300W) is not exceeded and that the amplifier's output is suitable for an 8 Ohm load.
Pros and Cons
Pros
- Excellent low-frequency output for bass-heavy applications.
- High RMS power handling (300W) accommodates demanding sound levels.
- Durable build quality with a steel frame and reinforced cone.
- Versatile 8 Ohm impedance is common in PA systems.
- Designed to integrate seamlessly into full-range PA cabinets.
Cons
- Specific 8 Ohm impedance may not suit all amplifier configurations.
- Frequency response limit of 3kHz means it's primarily a woofer, requiring a separate tweeter for full-range sound.
- Weight of 4.8kg requires secure mounting.
- Requires appropriate enclosure design for optimal performance.
Setup, Compatibility & Care
Setup:
- Enclosure Fit: Ensure the driver fits the mounting holes and depth of your existing or custom-built speaker cabinet. The dimensions are 160mm (depth) x 310mm (diameter).
- Wiring: Connect the speaker wires to the terminals, ensuring correct polarity (+/-) to match your crossover or amplifier.
- Sealing: Ensure a good acoustic seal between the driver gasket and the speaker baffle to prevent air leaks, which can degrade bass response.
Compatibility:
- Impedance: This driver is 8 Ohms. It should be used with amplifiers or systems that can safely handle an 8 Ohm load. Connecting to a lower impedance load than the amplifier is rated for can cause damage.
- Crossover: For full-range systems, this driver requires integration with appropriate mid-range and high-frequency drivers, typically via a passive crossover network set around 3kHz.
Care:
- Cleaning: Keep the cone and surround free of dust and debris. Use a soft, dry brush or a slightly damp cloth for gentle cleaning. Avoid solvents or abrasive materials.
- Environment: Protect the driver from excessive moisture, extreme temperatures, and direct sunlight when not in use.
- Handling: Avoid applying excessive pressure to the cone or voice coil assembly during installation or maintenance.
