This is a high-quality 15" replacement subwoofer driver utilizing my cast aluminium chassis and a British Paper Cone.

Available in 8 Ohm from stock and 4 Ohm by special order.

I have added extra cooling to this driver and used properly it will go louder than 800w RMS. Fit them in scoops, bandpass, sealed, ported, isobaric, etc...

Made from professional grade materials the BWP15s is a replacement driver for a subwoofer and features Kapton coils, ferrite magnets, paper cones with rolled cloth edge and push terminals.

This 15" subwoofer loudspeaker is ideal for those who prefer earth-shaking, chest-thumping bass with no compromises.

After a sub driver blew of mine, I searched the internet and eBay for new drivers and came across Bishop Sounds and saw the price and the reviews and ordered 2.

These drivers are powerful and punch you right in the chest when used with a crossover.

I will be buying the 800w full range drivers next.
