The BishopSound BSP18 18″ Subwoofer Driver delivers 800W RMS / 1600W Program / 3200W Peak Power with 98dB sensitivity and a smooth 35Hz–1kHz range, providing huge low-end punch. Its 4″ copper voice coil (inside/outside windings) ensures reliability under heavy loads, making it perfect for PA subwoofers, three-way enclosures, or bass guitar rigs. Engineered with a ribbed fibre-loaded cone, pressed steel frame, and British voicing, the BSP18 is designed for 100–250 litre ported cabinets, offering both strength and clarity. Unlike cheaper alternatives, it’s built for long-term durability, making it an excellent choice for replacement drivers or new cabinet builds in professional sound systems.
