BD215 - Summary

Built to take the rigors of touring the 18mm (13 plies) birch marine plywood, the Delta BD215 speaker is a twin 15″ upright full range speaker made from 100% Birch Marine Plywood boasting an incredible 1200w RMS power that's 2400 continuous/program or 4800w Peak!, these speakers will easily cater to audiences in excess of 5000 people.

The thick recessed grill gives added protection. Punching out Twice the power of other leading brands from overseas.

This 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%!

We have recessed the grilles and doubled its thickness, added 4 coats of high impact, textured jet black PU paint to withstand the inevitable bumps and knocks whilst on tour.

BD221 - Summary

My 21-inch Dual Subwoofer made with 18mm Marine Birch Plywood. This pair of passive neodymium subwoofers deliver 3000w RMS and over 139 dB SPL. Each driver in the cabinet is compartmentalized and delivers 1500w RMS, 4-ohm impedance.

The Twin 21" is housed in a sturdy cabinet and finished in a durable hard-wearing protective waterproof coating. The coating has a primary use for automotive linings, industrial and military coating markets due to the superior finish and the very high abrasion resistance. This box is perfect for touring or fixed installations.plywood ported box for sub-bass very little comes near for sound quality and power.

Those who know the capability of these speakers and are entertaining the masses need little more detail. But here is a quick glance.

The Subwoofers will be new to you as few are brave enough to harness the power of Neo drivers that deliver 1500w RMS each.
