Deaf Bonce DB-3.5K 12" – Extreme Bass with 3,500W RMS

The Deaf Bonce DB-3.5K 12" is built for those who demand brutal bass, extreme power handling, and uncompromising performance from a powerful 12-inch subwoofer. With an impressive 3,500W RMS and up to 7,000W maximum power, it delivers massive sound pressure with the deep and aggressive character Deaf Bonce is known for.

The high-strength ferrite motor provides excellent control and impressive force in the lowest frequencies. Combined with a long-throw suspension and 25 mm Xmax, the cone can move a huge amount of air while maintaining control, even when the subwoofer is pushed hard for extended periods.

The 3-inch PIAL voice coil is designed for high thermal durability and efficient cooling. This makes the DB-3.5K an excellent choice for extreme daily systems where the subwoofer is expected to play loud, deep, and reliably.

The pressed-paper cone combines low weight with high rigidity and fast response, while the foam surround provides powerful and controlled cone movement. The rigid aluminum frame minimizes flex and keeps the motor and suspension aligned during extreme excursion.

With a frequency response of 20–80 Hz, the DB-3.5K delivers deep, physical bass that can both be heard and felt. It is the ideal subwoofer for anyone looking to build a high-performance bass system with extreme power and maximum attitude.
