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.

This is a superb subwoofer and very little comes near for sound quality and power.

Many believe a 21″ driver is only good for near field applications. Our Bishopsound 21″ delivers far more.
