The SD18-1700EL is a high output low frequency transducer. The 18 inch 
(457mm) diameter piston will produce extremely high sound pressure levels 
at very low frequencies and is ideal for high level deep bass and sub woofer 
response in both live sound and 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 SD18-1700EL employs a very large 4.5 inch (114.3mm) diameter voice 
coil that provides an AES rated 1700 watts of continuous power handling 
and a full 6800 watts of peak rated power handling when sufficient amplifier 
headroom is available. It is recommended that the transducer be loaded into 
a properly designed vented enclosure and that active high order high pass 
filtering be employed if extremely high power levels are expected at low 
frequencies. The SD18-1700EL utilizes P Audio’s Auto Balanced Cooling 
(ABC) technology to not only improve transducer power handling and reliability 
but to also increase power compression performance by carefully balancing 
and directing airflow to critical areas.
The voice coil design is an “inside/outside” geometry with P Audio’s square 
wire technology to improve conversion efficiency and provide a very large 
cross-sectional area for superior cooling.
System linearity is achieved by employing magnetic flux demodulation 
devices in the structure to increase fidelity and sonic accuracy. The system
suspension has been designed specifically for high linear displacement and 
extended low frequency response. The double spider design insures very 
high displacement and linear response while maintaining excellent control.
The cone has been treated with a conformal coating designed to provide 
additional mechanical damping and moisture resistance.
The transducer chassis is a die cast aluminum design that insures a very 
high degree of structural integrity
