Funktion-One PSM18 is Reverse speaker a point sound source, a standard 15 "together with the compressed arrangement drives, more traditional foldback speakers, has a very great advantage, which uses a a very powerful 18" low-frequency driver, coaxially mounting a two-way compression driver in front of the low frequency driver 18 ', consisting of a three-way set structure.
Funktion-One PSM18 is a point sound source feedback speaker. It is a standard 15" plus a compression driver structure. Compared with traditional feedback speakers, it has very great advantages. It uses a very high-power 18" low-frequency driver. A two-channel compression driver is installed in front of the 18" low-frequency driver to form a three-channel concentrated structure. The crossover point between the middle and low frequency is 700Hz, and the intermediate frequency driver made of natural materials achieves crystal clear and high Analytical vocal frequency band. Newly developed ultra-high-speed 5" tone map 18" neodymium magnet low frequency unit, which is very suitable for drummer's return. The projection angle of PSM18 is 70° high-efficiency and controlled conical waveguide, point sound source The processing has the advantages of smooth coverage and minimized feedback. Like other Funktion-One speakers, it has Funktion-One driver technology, and equalization correction is not needed, so as not to affect the phase coherence and maximum sound pressure of the speakers Output and other performance.
