Maximum .  · A compression driver (CD) is a professional loudspeaker driver usually intended for mid or high frequency use with waveguides or horns. They can be thought of as similar to hifi dome tweeters in that they have a dome diaphragm and a motor. The main physical difference is that the dome is coupled to an exit tube via a phase plug where the dome is large than the www.doorway.ruted Reading Time: 4 mins.  · abstract={most of compression drivers have phasing plugs with annular slots. existing theories give recommendations for positioning of annular slots to suppress air resonances in compression chamber. however, interaction of diaphragm’s mechanical resonances with the compression chamber’s air resonances makes the problem very complex Author: Alexander Voishvillo.

The use of compression drivers, says Theory, makes possible the sb85’s claimed high power handling of W and very high sensitivity of 94dB/W/m. The soundbar’s maximum output is specified as a deafening dB/channel, or dB with all three channels driven, and its frequency range as 58HzkHz—no tolerance is given, but from my listening, 58Hz seems a realistic spec. The tweeter used in the sb25 is a ″ advanced-polymer compression driver manufactured by a third-party company to Theory’s specifications. A compression driver operates differently than a conventional dome tweeter. With dome drivers, the surface of the dome radiates sound directly into your listening space. However, compression drivers contain a chamber with a vibrating diaphragm; the sound emanates through a hole in the chamber and then out into the listening space. natural performance characteristics of drivers and horns. A compression driver depends upon the acoustical coupling of the horn for it to operate properly. The reason that compression drivers are called compression drivers is because, when the diaphragm moves, it “compresses” the air in front of it. There has to be a certain.

basic idea is to separately describe the acoustic source (horn driver) Furthermore, the models used in the early time of horn theory are simplified to a. the compression-driver phase plug and compression cavity is discussed and targets To discover the theoretical performance limits of compression drivers. ২২ ডিসেম্বর, ২০১১ A loudspeaker driver with new horn throat configuration has a indicate good agreement with the theory of the present invention.
