We strongly advise you to pre-order as we only hand make these in carefully controlled batches of 50 to maintain quality and reliability.

The BWP18 is our fastest-selling driver as it is deployed in other makers cabinets. More than often improving the sound quality and saving money on expensive branded replacement parts.

Powerful and proven in many different cabinet designs and classed by curly professional speaker cabinet designers as a superb cost-effective solution that does not break the budget. We load this driver in all our UK built sub-woofers as we need power and reliability.

Many compare this driver to the PD1850 but mine runs colder due to extra cooling and it is designed to outperform its rivals.

The Premium Series are high-quality PA speakers using a Cast chassis. Made from professional grade materials the Premium Series features Kapton coils, ferrite magnets, BRITISH paper cones with rolled cloth edge and push terminals.

All blacked up by our personal no quibble guarantee. If you break one and it's our fault, I will replace it Free of Charge. P.S. Not replaced for re-coned one yet!

This 18" Sub Speaker is ideal for use in Touring, club systems and when your customers want earth-shaking subwoofers
