We never use other people's drivers in our sub-woofers. We make our own as we want to match the drivers perfectly to the cabinet and our cabinets have stood the test of time for over 20 years. We have a less than 1% failure rate.

The combination of twin 15" and dual 18" subs is hugely popular and this is why.

Built to take the rigours of touring the 18mm (13 plies) birch plywood, the Delta BD215 speaker is a twin 15″ upright full range speaker made from 100% Birch Marine Plywood boasting an incredible 2400 continuous/program or 4800w Peak! These speakers will easily cater to audiences in excess of 6000 people.

This BD215 cabinet includes 2 x 600w RMS BishopSound BDP15FR cast Alloy woofers and 1 x 100w BRC175 Titanium Compression Driver. So the drivers in this cabinet are 1300w rated. I guess you ask why we don't rate this cabinet at 1300w RMS? I guess we like some headroom which is why our failure and returns rate is less than 1%!

The BD218 dual 18" subwoofers are made for those constantly on the road touring my all plywood bass reflex port design enclosure, loaded with my BDP18 die-cast aluminium, high powered 18" sub frequency driver that utilizes our Brtish Paper cones and extra cooling for better heat dissipation, high power handling capacity, and improved efficiency.

These long-throw cabinets have acoustic foam behind the extra thick ding proof grille to prevent dust and moisture ingression.

The rear panel connector upward water-resistant backplate carries 2 Neutrik Speakon NL4 connectors. In and Out for linking.
