PW418N | Die Cast Aluminum Basket 4″ Voice Coil 8.0Ω
The PW418N is an very high output low frequency transducer. The 18 inch(460mm)diameter piston will produce extremely high sound pressure levels at very low frequency and is ideal for high level deep bass and subwoofer response in both live sound and recorded music venues.the operating range is 30hz to 200hz.the transducer uses high enery neodymium magnetic to achieve a very high acoustic output to weight ratio.
The PW418N employs a large 4inch diameter voice coil that provides an AES rated 1500 watts of continuous power handing and a full 3000 watts of peak rated powe handing when sufficient amplifier headroom is available .it is recommended that the transducer be loaded into a properly designed vented enclosure and suitable active high pass filtering be employed if extremely high power levels are expected at low frequencies.the PW418N utilizes CFS auto balanced cooling technology to not only improver transducer power handing 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” API copper wire technology to improve conversion efficiency and provide a very large crss-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 han been designed specifically for high liner displacement and extended low frequency response. The double spider desigen insures very high displacement and linear response while maintaining excellent control.the cone has been treaed 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. The cast chassis base venting and large motor venting ensures efficient ventilation of the unit to keep power compression to a minimum.
