Home Theater Series 4k Neo Carbon Fiber Subwoofer

For customers seeking the highest level of performance, the optional carbon fiber composite cone and dust cap upgrade provides increased stiffness, improved strength-to-weight ratio, and greater resistance to cone flex under extreme power levels. These characteristics can improve sensitivity, transient response, accuracy, and long-term durability while helping maintain exceptional linearity at high excursion. The result is tighter, cleaner bass reproduction with lower distortion and increased output efficiency. While our standard paper cone remains an excellent performer, the carbon fiber upgrade is designed for enthusiasts looking to extract every last bit of performance from their system.

Rated at a conservative 4,000 watts RMS, each Pierce Audio Home Theater Series 4K Neo-Mag Carbon Fiber Subwoofer is custom designed and hand-built in the USA. Featuring our premium carbon fiber composite cone technology, the 2026 Series 4K Neo-Mag Carbon Fiber delivers increased stiffness, an exceptional strength-to-weight ratio, reduced cone flex, improved sensitivity, and outstanding durability under extreme power levels.

Engineered for the most demanding home theater enthusiasts, this 4,000-watt masterpiece is capable of reproducing the deepest frequencies with authority while maintaining exceptional accuracy, dynamics, and musical detail. At its core are eight pillars of genuine N52 neodymium magnet power, providing tremendous motor strength, efficiency, and control.

Each driver is equipped with an American-made 4-inch, four-layer flat copper wire voice coil wound on a premium BAA former and features an impressive 3-inch winding height for exceptional thermal handling and long-term reliability.
