Ciare PW257 – 10″ High-Output Low-Frequency Driver
The Ciare PW257 is a 10-inch pro-audio mid-bass/low-frequency driver built for serious performance. Designed in Italy with premium materials and robust design, this driver delivers strong bass fundamentals, solid power handling, and reliable sensitivity. The PW257 is aimed at applications where tight, clean low-frequency output is needed without resorting to massive cab sizes or excessive amplifier demand.
With its balance of excursion, efficiency, and rugged build, the Ciare PW257 is well suited for vented cabinets, full-range tops, fill speakers, and install systems that require dependable low-mid and bass response under tough conditions.
Deep and Controlled Low-Mid Output
Featuring a nominal diameter of 250 mm (10 in), the Ciare PW257 moves enough cone area to deliver impactful low-mid and bass frequencies. Its frequency range of 50 Hz to 3000 Hz gives the driver a wide usable bandwidth, allowing it to reproduce the low bass and still maintain clarity well into the midrange.
In vented or reflex enclosures, the PW257 delivers punch on bass guitar, kick drums, and provides foundation for full-range systems without introducing mushy bass or bleeding midrange. The output remains tight and defined, even at elevated SPLs.
High Power Handling and Thermal Stability
The Ciare PW257 is rated with nominal power handling of 400 W and continuous program power handling of 800 W, giving it good headroom for dynamic peaks and real-world usage. The driver includes a 75 mm (3-inch) voice coil, engineered to cope with heat and mechanical stress, maintaining performance without power compression under heavier loads.
Its thermal path, motor design, and overall mechanical structure combine to ensure that even during extended use or higher gain applications, the PW257 holds its tone—bass remains present, midrange stays clean, and distortion stays low.
Efficient Sensitivity and Load Compatibility
With a sensitivity of 96 dB (1W/1m), the Ciare PW257 offers excellent output per watt, letting systems reach usable SPLs without overloading amplification. This efficiency is a key benefit when drive power or amplifier capacity is constrained.
The driver’s performance makes it effective in both portable PA scenarios and fixed installations, where headroom matters and you want reliable, repeatable loudness from each cabinet or driver stack.
Electrical Stability and Integration
The Ciare PW257 operates at a nominal impedance of 8 Ω, with a minimum impedance around 6 Ω, giving stable and predictable behavior when paired with amplifiers, crossover networks, or DSP systems.
Designers can rely on that electrical consistency to align crossover points, match amplifier output, and maintain reliable behavior across multiple driver units without unexpected dips or strain.
Rugged Design for Real-World Use
Ciare has built the PW257 to survive the demands of pro audio use. The driver uses a treated paper or equivalent rigid diaphragm, a robust suspension system, and a steel or aluminium frame to withstand vibration and stress. Its voice coil former and winding are selected for durability and thermal resilience.
This means the PW257 can endure repeated use, service, transport, and high output without mechanical fatigue, maintaining function and sound quality over time.
Ideal Applications
The Ciare PW257 is perfect for:
-
Low-mid or bass modules in full-range top boxes
-
Vented mid-bass cabinets for FOH or stage monitoring
-
Fill or side-fill speakers where clean bass and efficient output are required
-
Portable PA rigs needing strong low-mid response without big size or weight
-
Install systems where reliability and consistent performance are non-negotiable
It’s a go-to driver for audio professionals who need strength, clarity, and dependability without overkill.
