The PXH64 was engineered to be a powerful medium/long throw mid/high-frequency cabinet in a coaxial configuration, covering the frequency range from 150 Hz to 19 kHz.
To obtain the highest possible on-axis sound pressure levels and clear and intelligible sound reproduction over long distances, the PXH64 mid/high unit is entirely horn-loaded. The coaxial arrangement of the High Frequency CD horn and the Mid Frequency 12″ speaker (also horn-loaded) creates a precise coverage pattern of 60°H x 40°V over a frequency range from 400 Hz–17kHz, ensuring equal sound within the coverage area. The HF range from 1.150 kHz upwards is reproduced by a Neodymium 1.4” driver with a 3” voice coil and a Constant Q horn, whilst coverage in the mid-range from 150 Hz to 1.25 kHz is provided by a low power compression 12” driver loaded by a midrange horn.
Wider coverage can be achieved using multiple tops, laterally stacked or flown. The PXH64 cabinet must be rotated (90°) to maintain at minimum the comb-filter effects.
A Tilt Unit (available as an option) permits the cabinet to be angled in 5° increments up to a maximum of 15°; as a result, the upper cabinet can be aimed directly at the audience area even when the system is ground stacked.
