P.Audio CXP-21 SUB
The P.Audio CXP-21 SUB is a very high performance professional sound reinforcement system sub woofer. The CXP-21 SUB is an active design that features fully bridged class D amplification and a universal power supply. The design includes 96kHz DSP processing with high order IIR filtering and multiple presets for design optimisation. The CXP-21 SUB is designed for general purpose sound reinforcement applications where substantial deep bass and ultra-low frequency output is required. The CXP-21 SUB is ideal for fixed installation applications such as restaurants, bars, retail outlets, and general purpose indoor public address and full range music systems. The design includes four high quality casters mounted on the back of the enclosure The CXP-21 SUB combines a 2000w peak power amplifier with a matched pre amp. The precision 96kHz DSP PCB combines an electronically balanced input and output XLR connection. The DSP provides all necessary filtering and equalisation, and peak limiters to optimise system dynamics and performance. The is also a level control that allows the subwoofer level to be set independently from the system level. The optional USB-RS485 cable allows full remote control of all DSP parameters, and gives the user access to extra equalisation and system delay as required. The low frequency section is a 21 inch (533mm) transducer that features a large format voice coil 5 inch (127mm) diameter voice coil. This design assures ultra high power handling and high reliability. The vented enclosure design has been optimized for use with this low frequency device and is tuned for deep bass and sub woofer applications in professional environments. The enclosure is constructed with high quality plywood and finished in a very durable polyurea coating. The system includes a top hat style stand adaptor for use with the CXP-121C, CXP-151C, CXP-122F or CXP-152F ultra high performance full range enclosures.
