User manual ALTEC LANSING 19 HI FI SPEAKER

[. . . ] After your first meeting with the client, you are faced with another dilemma: the only place to hang the speakers is right in front of the stage, and the auditorium can't afford a cluster of DSP-steered four-way speaker systems. The DE-series uses a proprietary high efficiency, high output single magnet point-source Duplex® speaker "engine" mounted in a 500 Hz bass horn cabinet. [. . . ] The DE-series uses a proprietary high efficiency, high output single magnet point-source Duplex® speaker "engine" mounted in a 500 Hz bass horn cabinet. This unique combination virtually eliminates the interference and cancellation you get from adjacent devices in traditional two-way speaker systems, while allowing you to steer most of the damaging low frequency energy away from the performance areas. Altec's new LF215-4A dual 15"/380mm subwoofer system provides full-range music playback ability. The Altec Lansing DE6412 and DE9412 provide you with the ability to reproduce both music and the spoken word. . . at a price point that allows you to profitably include it in the majority of your performance venues. The DE-series from Altec Lansing delivers the best of both worlds. The heart of Altec's DE6412 and DE9412 is the unique point-source 12"/300mm Duplex® engine component. The high frequency diaphragm is on the back of the magnet structure, and the low frequency voice coil is on the front.
