The Dayton Audio PCS175-8 Poly Cone Subwoofer is a 6-1/2-inch, 8-ohm driver designed to deliver tight, controlled bass in compact enclosures. Engineered for versatility, this subwoofer excels in both car audio systems and home theatre projects, making it an ideal choice for DIY enthusiasts seeking to upgrade their low-frequency performance without sacrificing space. Its robust construction ensures reliable operation in sealed or ported cabinets, offering a balanced response that complements mid-range speakers seamlessly.

At the heart of this driver lies a durable polypropylene cone, which provides consistent sound reproduction and long-lasting performance even in demanding environments.
