The BishopSound BDP18 18″ Subwoofer is a high-performance, ferrite-based driver designed for professional PA, bass, and stage applications. Featuring a 100 mm (4″) copper voice coil, laminated double silicone spider, and a water-resistant curvilinear cone with triple-roll surround, it delivers precise, linear excursion and robust low-end punch. Rated at 4000 W peak power with 97 dB sensitivity, it excels in both single and twin 18″ plywood subwoofer enclosures.

Ideal for compact vented designs from 120 litres, the BDP18 covers 35–1000 Hz with an Xmax of 11.3 mm, offering deep, clean bass in demanding live or installation environments. Customers frequently note that it outperforms top German and Italian brands at a fraction of the price, making it a cost-effective yet professional-grade choice for high-power sound reinforcement systems.
