Dayton Audio PCS175-4 6-1/2″ Poly Cone Woofer 4 Ohm
Engineered for precision and durability, the PCS175-4 woofer features a damped poly cone paired with a rubber surround, which together provide a controlled yet extended frequency response from 50 Hz up to 5,000 Hz. The use of a poly cone reduces unwanted resonances, while the rubber surround enhances the driver’s longevity. This construction ensures that the woofer delivers a smooth and natural sound, making it a solid choice for both speakers and custom audio projects.
At the heart of the PCS175-4 is an aluminum former with a 4-layer voice coil, allowing for improved power handling and thermal management. This design supports a continuous RMS power handling of 30 watts, making it suitable for integration with a wide range of amplifiers and audio systems. The ferrite magnet motor structure ensures stable, reliable performance throughout the woofer’s operating range, minimizing distortion even at higher volumes.
The low-profile stamped steel frame not only adds to the structural integrity of the woofer but also makes it exceptionally easy to install, especially in surface-mounted or shallow enclosure designs. With a sensitivity of 89.2 dB at 2.83V/1m, the PCS175-4 delivers impressive output and efficiency, making it suitable for use in both home audio and DIY speaker kit applications where space and power efficiency are important.
Whether used as a replacement driver or in new custom builds, the Dayton Audio PCS175-4 stands out for its blend of performance and versatility. Its frequency response and controlled excursion make it an excellent choice for midbass duties in two-way or three-way systems. The woofer is also compatible with a wide array of woofers and crossover components, offering flexibility for DIYers and professionals alike looking to optimize their audio setups.
The PCS175-4 is a direct replacement woofer for the Dayton Audio B65 and B65A bookshelf speakers, offering a simple solution for B65 speaker repair and restoring the original midbass performance.
