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.

Many suggest that my BWP15s Performs better than the PD1550 - I will leave you to judge.

The technical specifications are accurate and interesting.
