Applications
The P Audio C18-4800CA is a high output low frequency transducer.
The C18-4800CA is a upgraded design that features many of P Audio’s new technologies & performance upgrades.
The 18 inch (457mm) diameter piston will produce extremely high sound pressure levels at very low frequencies & is ideal for high level deep bass & sub woofer response in both live sound & recorded music venues.
The operating range is 30Hz to 200Hz.
The transducer uses high energy ferrite magnetics to achieve a very high acoustic output to weight ratio.
The C18-4800CA employs a large 3.9 inch (99.3mm) diameter voice coil that provides an AES rated 1200 watts of continuous power handling & a full 4800 watts of peak rated power handling when sufficient amplifier headroom is available.
The transducer has been optimized for use in properly tuned vented enclosures.
The addition of an active high pass filter is always recommended if ultra high input levels are expected at low frequenciea The C18-4800CA utilizes P Audio’s Auto Balanced Cooling (ABC) technology to not only improve transducer power handling & reliability but to also increase power compression performance by carefully balancing & directing airflow to critical areas.
The voice coil design is a bobbin wound geometry w/P Audio’s rectangular wire technology to improve conversion efficiency & provide a large cross-sectional area for superior cooling.
The transducer employs magnetic flux demodulation devices in the structure to increase system fidelity & sonic accuracy.
The suspension has been designed specifically for high linear displacement & extended low frequency response.
The transducer chassis is a die cast aluminum design that insures a very high degree of structural integrity.
