Ideal for New Designs and Subwoofer Replacement

With its 8" frame, 4Ω impedance, and subwoofer-focused design, the PCS8-4 is a great replacement option for many existing powered and passive subwoofers. It is also a drop-in replacement woofer for the Dayton Audio CS800 powered subwoofer, making it especially useful for restoring that model to proper performance. Whether repairing an older subwoofer or building something new, the PCS8-4 offers a practical balance of fit, value, and output.

Modern Styling, Clean Installation

The grey poly-coated paper cone gives the PCS8-4 a balance of durability and modern style. The matching inverted dust cap creates a cohesive look that works well in both hidden and exposed-driver installations. A large-roll rubber surround supports controlled excursion, while the shallow flange stamped steel frame provides solid support with a clean finished appearance.

Efficient Output with Reliable Cooling

With a 43 Hz Fs, 90 dB sensitivity, 5 mm Xmax, and low Vas, the PCS8-4 is built for useful output from compact bass systems. Its high sensitivity helps produce strong output from modest amplifier power, making it a good fit for powered subwoofers and small bass cabinets. Extensive venting through the voice coil former, pole piece, and under-spider area helps move heat away from the motor during demanding playback.

Built for Compact Bass Projects

The PCS8-4 is a great choice for compact subwoofer builds, replacement repairs, bass modules, and budget-friendly DIY speaker projects. Its 150 watt RMS power handling, strong ferrite motor, aluminum voice coil former, and 4-layer voice coil give it the durability needed for real subwoofer use. For builders who need an affordable 8" driver with solid output, clean styling, and impressive low frequency extension, the PCS8-4 is an extremely versatile option.
