| The P21SUB is a high performance quarter-wave loaded subwoofer system. extending the low frequency response of Nova’s PARIZ line-array and point source systems, in both permanent and portable applications. Featuring a state-of-the-art 21” Neodymium transducer, this subwoofer is designed to offer maximum, prolonged high impact SPL performance from a relative small footprint.For this, the latest materials and innovations have been applied: A very large displacement transducer with all-carbon fiber cone + dust cap, 5.3” voice-coil with vented triple-spider frame plus optimized low resistance impedance, and port-vented magnet structure to maximally reduce power compression.The extensively internally-braced cabinet features features double-tuned, high-pressure loading, through a rounded 236mm/9.3” diameter low-tuned bass-reflex vent and a wide, high-tuned quarter wave tunnel. This provides optimised breathing at high SPLs, yet keeping the total system weight to a minimum. Slider feet on cabinet bottom and side enable stacking of multiple P21SUB’s into vertical LF arrays. The cabinet is constructed from plywood and is covered with weather and impact protecting Nova Polyurea Protection finish. The front of the loudspeaker is protected by a robust metal front grill with acoustically transparent foam. Each side includes two handles On top of the cabinet are cutouts for the P212. The acoustical and mechanical design enables the P21SUB to be used as a very powerfull subwoofer or extremly deep Infra Sub. The P21SUB is compatible to all P-Series and MF-Series fullrange, line array or mid/high cabinets. Ideal to use where very high SPL, deep and clear subwoofer performance is needed. |
