- 4.5" Very Large Format Voice Coil
- 6800 Watts Peak Power Handling
- Active Balanced Cooling
- Ferrite Magnetics
- Square Wire Inside/Outside Coil Design
- Double Spider Suspension Integrated Demodulation Rings
- Die Cast Aluminum Chassis
(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.
