![]() The cutoff frequency is equal to the wavelength corresponding to the circumference of the horn mouth. Their disadvantage is that their frequency response is more uneven because of resonance peaks, and horns have a cutoff frequency below which their response drops off. Therefore, horns are widely used in public address systems, megaphones, and sound systems for large venues like theaters, auditoriums, and sports stadiums. ![]() Significant improvements have been made, beginning with the constant directivity horn invented in 1975 by Don Keele. The result is greater acoustic output power from a given driver.Ī major problem of horn speakers is that the radiation pattern varies with frequency high frequency sound tends to be emitted in narrow beams with poor off-axis performance. The horn can be thought of as an acoustic transformer that provides impedance matching between the relatively dense diaphragm material and the less-dense air. Wente of Western Electric, 13 multicell horns have been used in loudspeakers since 1933 to address the problem of directivity at higher frequencies, and they provide excellent low frequency loading.Ī common form (right) consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air.Īnother type is a woofer driver mounted in a loudspeaker enclosure which is divided by internal partitions to form a zigzag flaring duct which functions as a horn this type is called a folded horn speaker. ![]() You can also order your gloss coat in any other colour on the RAL colour chart for 10 extra. It is recommended that you give some support to the mid portion of the horn to take pressure off the mounting bracket when using a heavy compression driver.Īvailable in a variety of standard colours for no extra charge. Others like to sit the horn directly on top of their speaker. There are no screw holes on the front of this horn because some people prefer to build their own mounting brackets that hold the horn from the back.
