PT 9

PT 9 single


Perfect sound and simple operation.


The Fohhn® WaveLine line array is a complete system consisting of perfectly developed speakers and specially adapted amplifiers and control technology. The Perform WaveLine is a completely symmetric line array that is capable of generating virtually identical acoustic sound patterns on the right and left and can be aligned accurately and symmetrically. The PT-9 operates with two of the most powerful 10” speakers (neodymium) currently on offer, which are positioned symmetrically so that the horn produces a dispersion angle of approximately 110° (twin coaxial). There is a diffraction gap between the two 10” speakers that separates the two bass reflex chambers with help from the multi-channel phase EQ. The spherical sound wave dispersed by the 2” tweeters is converted into a coherent wave front by the time delay in the multi channel phase EQ. The wave then exits the diffraction gap to produce a cylindrical wave across the entire frequency range. The 4” voice coils on the 2” high-frequency driver can produce a relatively deep crossover frequency (approx. 650 Hz), whereby the acoustic performance is drastically increased, preventing load dumps from 10” speakers at approx. 900 Hz.
