Ciare PW455 – 18″ High-Power Low-Frequency Driver
The Ciare PW455 is a high-output 18-inch low-frequency driver engineered for professional audio applications that demand deep, clean bass and robust performance. Designed in Italy, this transducer combines high power handling, extended excursion, and refined efficiency—making it ideal for vented subwoofer enclosures, bass modules in full-range cabinets, or high-output handling systems.
Built around a ferrite motor and copper-wound coil, the Ciare PW455 delivers strong mid-bass energy alongside reliable thermal endurance, ramping up its value in sound reinforcement and fixed installation systems.
Powerful Low-End and Wide Frequency Range
With a nominal diameter of 450 mm (18 inches), the Ciare PW455 moves air effectively for impactful low-frequency output. Its frequency range spans 35 Hz to 1200 Hz, providing strength in both sub-bass and lower midrange duties—making it versatile for a variety of cabinet designs.
Whether used in vented sub enclosures or as the lower band in two-way boxes, it delivers tight, dynamic bass response with authority and minimal coloration.
Superior Power Handling with Thermal Control
The PW455 is rated for 900 watts nominal power handling, with a robust 1800 watts continuous program rating that gives extensive headroom for dynamic musical peaks and live sound dynamics. Its 100 mm (4-inch) sandwich aluminum voice coil, wound on a Kapton former and paired with a ventilated gap, keeps thermal compression to a minimum during extended high-output operation.
This thermal design, coupled with a demodulating cooling structure, ensures sustained, distortion-free bass even under continuous use in demanding environments.
Efficient Sensitivity and Performance
The Ciare PW455 achieves a sensitivity of 100 dB (1W/1m) in its 8-ohm variant—an excellent number for an 18-inch driver. This high sensitivity translates into loud, controlled bass output requiring less amplifier power, ideal for portable striking systems and large-format PA, where dynamic response and headroom are critical performance factors.
It supports substantial acoustic output while conserving amplifier resources—a plus for streaming energy efficiently without sacrificing performance.
Solid Impedance and Integration Characteristics
Operating at a nominal impedance of 8 Ω, with a minimum impedance of around 5.5 Ω, the Ciare PW455 integrates easily with common audio systems and crossover designs. Its impedance curve is predictable and stable—which simplifies both passive and DSP crossover integration, allowing designers to build reliable, repeatable systems.
Rugged Construction for Professional Environments
The PW455 features a fiber-treated cone for stiffness and acoustic clarity, a robust Nomex fabric surround for permit high excursion, and a demodulating ring for a linear magnet field. These components ensure its reliability under prolonged use or harsh conditions.
Encased in an aluminum basket with mounting optimized for airflow and structural rigidity, this driver is ready for mobile rigors, high-SPL situations, and long-term install durability.
Ideal Applications
The Ciare PW455 excels in:
-
High-output vented subwoofer systems
-
Bass module integration in compact two-way cabinets
-
Touring PA front-end bass reinforcement
-
Sub-satellite systems in distributed line arrays
-
OEM speaker designs requiring consistent, high-efficiency performance
Its balance of low-frequency reach, efficiency, and strength in build quality make it a versatile, go-to driver for serious sound systems.
