Ciare 18.00SW – 18″ High-Power Subwoofer Driver
The Ciare 18.00SW is a professional-grade 18-inch low-frequency driver engineered for high-output subwoofer applications. Designed for demanding audio environments, it delivers deep, controlled bass, high sensitivity, and reliable performance in both touring and fixed installation systems.
With robust materials and precision engineering, the Ciare 18.00SW offers dependable low-frequency output, making it ideal for vented subwoofer enclosures, bass modules in full-range cabinets, or high-output sound reinforcement systems.
Powerful Low-Frequency Performance
The Ciare 18.00SW features a nominal diameter of 450 mm (18 inches), providing substantial cone area to move large volumes of air. Its frequency range spans 20 Hz to 200 Hz, producing authoritative sub-bass and low-frequency output while maintaining clarity and control.
Whether deployed in dedicated subwoofer cabinets or as part of a multi-way system, this driver offers clean, distortion-free low-end performance, making it suitable for live concerts, club installations, and high-output PA systems.
High Power Handling and Thermal Efficiency
The Ciare 18.00SW is engineered to withstand demanding usage, with a nominal power handling of 1000 W and continuous program power of 2000 W. Its 100 mm (4-inch) voice coil, constructed with copper on a high-temperature Kapton former, manages heat efficiently during extended high-SPL operation.
The ventilated motor structure and robust coil design ensure consistent output under long-duration use, minimizing thermal compression and delivering stable bass performance at all times.
Efficient Output and System Headroom
With a sensitivity of 91.5 dB (1W/1m), the Ciare 18.00SW converts amplifier power into high SPL efficiently, making it an excellent choice for systems that require impactful low-frequency response without excessive amplifier strain.
This efficiency, combined with its extended excursion capability, provides significant headroom for transient-heavy content such as kick drums, bass synths, and low-end percussion in both live and installed environments.
Electrical Stability and Integration
The Ciare 18.00SW operates at a nominal impedance of 8 Ω, with a minimum impedance of approximately 5.5 Ω, offering predictable electrical behavior for seamless integration with amplifiers and crossover networks.
System designers benefit from its stable impedance characteristics, which simplify cabinet design, crossover selection, and overall system tuning.
Rugged Construction for Professional Use
Built with a die-cast aluminum basket, treated paper cone, and reinforced suspension, the Ciare 18.00SW is designed for durability and longevity. The rubber half-roll surround provides controlled cone excursion, while the demodulating motor ring minimizes distortion and improves linearity.
These mechanical and acoustic features ensure that the driver maintains performance integrity, even under prolonged use and high-output conditions.
Ideal Applications
The Ciare 18.00SW excels in:
-
High-output vented subwoofer systems
-
Bass modules in two-way or multi-way cabinets
-
Touring PA and concert subwoofers
-
Fixed installations requiring deep, accurate bass
-
OEM designs that prioritize reliable low-frequency performance
Its combination of deep extension, power handling, and mechanical durability makes it a versatile solution for professional audio designers and installers.
