With our cast alloy BDP12 woofer and BRC135 HF titanium compression driver, this 2 -way monitor is crystal clear from 50 Hz up to 18KHz. The 45-degree angle is perfect for performers to hear precisely what they are singing or playing.

Performers who use them have voted the BishopSound Delta Wedge Monitor the Number 1 for clarity and performance. Try one! Clarity is king with this my BDM12P, the ultimate stage wedge monitor.

These Delta Wedge Monitors are made to meet the toughest conditions whilst touring in the studio or in a fixed club situation. Renonowed for getting the angle correct I have been making wedge monitors for a significant number of years.

This cabinet has acoustic foam behind the extra thick "ding proof" grille to prevent dust and moisture ingression.

The 2 Speakon sockets are concealed on the rear of the delta wedge monitor to allow ease of linking and protection against the rigours of a live stage performance.

Birch plywood construction means that if artists feel the need to climb on the top no damage is done. And if the roadie is on a promise rough handling on "pull out" will not be apparent.

The tough 3 stage paint process gives a waterproof highly durable finish. DuraTex® is a high-performance protective texture coating with tremendous adhesion to wood. It is a 3 part spray process creating a tough, beautiful, weather-resistant and easily maintained texture surface. DuraTex® provides the ultimate protection to wood speaker cabinets, road cases, and other applications. DuraTex® is a blend of highly technical polymers, and special LOW V.O.C coalescent's for creating high relief spatter textures.

This 12 Stage Monitor houses my purpose made 12-inch professional BDP12  stage loudspeaker, designed to meet the professional standards of live audio application and delivers a flat response to provide the most accurate audio reproduction possible whilst being exceptionally powerful.

Learn more about the BDP12 in my drivers' section on this website.

Superb clarity combined with ultimate durability makes this monitor (housed in a durable birch ply casing) with it hard-wearing finish the best in class for its price because it delivers the acoustic needs and qualities required by the vocalist performing at a live gig.
