P-Audio SD18-1700EL 18" Driver Four Pack
Please note - this is not the same driver as the original SD18 specified for X1 subwoofer, this driver is not suitable for the X1 subwoofer.
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 ensures 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 aluminium design that ensures a very high degree of structural integrity.
