EAW - Eastern Acoustic Works, Inc.","Long throw LF Phased PointSource Technology™ module. (4) 15-in. LF (two separate push\/pull cells) PPST™ systems build arrays for the largest spaces. Pre-configured DSP defines coverage by integrating cells and modules to fit its application.","The KF930 is a dedicated low frequency module engineered for use with Phase PointSource Technology digital signal processing in the creation of PPST arrays. The system comprises two cells each consisting of two specially designed 15-in. low frequency cones loaded magnets-out on angled baffles to maximize acoustical coupling of the drivers. Both horizontal and vertical coverage are determined by PPST processing. PPST processing allows the use of a variety of directivity enhancing schemes including line arrays and EAWs Tuned Dipolar Array technology. Properly PPST settings can also maximize low frequency output and LF extension. The specific needs of the application should determine which type of settings are implemented. A toggle switch controls the KF930s only passive filtering which provides appropriate settings for modules located in inner or outer columns. Outboard digital signal processors must provide all other system control.
