EM12-LB600


The P Audio EM12-LB600 is a high performance 12 inch (305mm) diameter low frequency/full range transducer. The EM12-LB600 is an excellent choice for full range two way designs where high reliability and power handling as well as excellent transient detail are specified. The EM12-LB600 features 2400 watt peak power handling (600 watts continuous) and extended bandwidth frequency response. The unique 3.5 inch voice coil diameter provides an excellent balance between high power handling and controlled moving mass. The result is a high efficiency design that offers high impact full range response and high reliability. The 3.5 inch coil design offers less moving mass than a conventional 4 inch design. The reduced moving mass offers superior transient response as well as extended high frequency response. The unique 3.5 inch coil diameter offers higher reliability and higher power handling then conventional 3 inch (76mm) designs.

The EM12-LB600 offers a 45Hz to 3500Hz useable bandwidth. The performance of the EM12-LB600 is optimized when using a high pass 4th order Butterworth filter tuned to near the enclosure vent frequency. Although the woofer is rated to 3500Hz, typical high frequency crossover points will be based on the compression driver and horn combination used for the high frequency section.
