I never use other people's drivers in my subwoofers. I make my own as I want to match the drivers perfectly to the cabinet and our cabinets have stood the test of time for over 20 years. We have sold countless BWP18 subwoofer drivers with no returns. We carry spares and replacement parts but rarely need them. Any questions contact Andrew Bishop

Remember there are no middlemen at BishopSound. We design, manufacture and sell directly to you.

No middlemen at Bishopsound means fantastic value for money and great savings for you. Direct to you from my factory.

Enjoy the punchy tight LONG THROW bass and tour the UK with the Best of British Dual 18" Subwoofers.

Important information about subwoofers

Subwoofers are designed to reproduce low bass audio signals between 30Hz and 150Hz. Driving them with full frequencies will cause permanent damage, so they should only be operated with a passive low-pass filter, a crossover network, or an active electronic crossover or speaker management system.

Please go to my blog section to learn more about driving subwoofers safely.
