Apocalypse DВ-5.5K 15" D1/D2 | 5500W RMS | 15" Subwoofer

The Deaf Bonce 5.5K 15" is built for extreme power applications where thermal strength, motor force, and structural rigidity matter more than anything else. With a true 5,500W RMS rating, a massive ferrite motor, and a 4.5" PIAL voice coil, this subwoofer is engineered to survive the kind of abuse that destroys ordinary drivers. A composite carbon‑sandwich cone, long‑throw suspension, and a reinforced aluminum frame give the 5.5K the precision and durability needed for violent low‑frequency output from 20–80 Hz. If you’re building a no‑compromise daily monster or a competition‑ready setup, the 5.5K Series delivers the output, control, and reliability that Deaf Bonce is known for at the highest levels.
