The line array speaker system PS22D is a dual frequency single
drive speaker. It provides a frequency range of 65Hz-18kHz. It
consists of a 75 core (voice coil) 36 core throat compression
tweeter and two 12 inch bass drivers to form a speaker system with
great dynamic margin.
The low frequency part of the PS22D uses two 450W 12 inch paper
basin bass drivers, and the two bass drivers work in parallel
symmetrical structure. The high frequency part uses a 75 core
(voice coil) titanium film compression driver, through a plane wave
converter combined with a 90 degree exponential curve constant
pointing horn to produce a consistent wave front. The PS22D
produces a peak sound pressure level of up to 135dB with a
sensitivity of 99.5dB.
PS22D cabinet is trapezoidal, the adjustable angle of each cabinet
is 0-10 degrees, adjustable every 1degree. The hanger is made of
high-precision and high-strength steel and aluminum alloy, which
ensures the quick and efficient connection and safe hanging of the
speaker. When hanging more than one speaker, the hanger has a
safety factor of 6:1. The cabinet is made up of 18mm plywood,and
the surface is made of wear-resistant black matt paint. There are
two humanized handles on both sides of the speaker, which makes it
safer to carry. The back terminal block has two NL-4 four core
sockets. Black perforated iron mesh lined with black waterproof
mesh cotton can protect the speaker driver.
