    Compression drivers and the horns that comprise the horn loudspeaker system have been a part of the audio industry from the very beginning of product development in sound reinforcement systems. As is true for cone loudspeakers, most of the early development in horn loudspeakers began when sound was first put to picture back in the 1930s when the first “talking films” were released.  Since that time, compression driver technology coupled with horn development advances have been in the areas of… View this story

    An Examination Of Bandwidth, Dynamic Range And Normal Operating Levels
    bandwidth
    John Eargle & Chris Foreman 02/26/13 05:12 PM,
    Audio signals are, of course, speech and music, and in this article we will examine the nature of those signals in terms of their requirements in bandwidth, dynamic range and normal operating levels. The nature of peak and average levels of music and speech will be discussed. In addition, we’ll look at the standard methods of dealing with signal peaks and required shifts in signal operating levels. AUDIO SPECTRA The data of Figure 1 shows the approximate limits of bandwidth… View this story
