Designed for portable PA applications including Point Source, Front of House, side and drum filling as well as sound reinforcement. The low distortion waveguide provides optimal 70° H x 50° V dispersion for optimal audio performance. The result is exceptional British audio quality.

The high excursion British Designed Cast alloy BDP15FR 15" LF Driver includes a low mass voice coil for improved transient response and punches in the low-end. The BishopSound titanium dome BRC175 44.4mm compression driver delivers extended high-frequency reproduction.

Combined together, the two drivers produce an extended frequency range (40 Hz, 20 kHz -10 dB) capturing every note and tone of the original recording just as it was intended. The drivers are matched using an internal passive crossover network in a reflex-loaded enclosure for optimal audio performance.

Marine Birch Plywood 21" cabinet finished in Heavy Duty black splatter paint it will withstand all the knocks and scrapes gathered through touring.

Fitted with my purpose made BWN21 12kg driver with its 5-inch voice coil which goes down to 27Hz.

The neodymium 21" driver is very efficient and takes modest amplification to drive it. Study our BP4k amplifier.
