The rectangular planar wavefront thus obtained can be loaded by an appropriate horn or waveguide to ensure the necessary coverage.įour high-efficiency 8” mid woofers: two band-pass loaded (110 – 400 Hz) and two reflex high-pass (110 – 1250 Hz) loaded by the sides of a waveguide with a 90° dispersion angle are connected in parallel without any type of passive crossover, so can both be powered using one amplifier. Discover 12368 Butterfly outline vectors for royalty-free download from the Depositphotos collection. that of a compression driver) and transforming it into a rectangular planar wavefront at its output, keeping signal paths identical from every emission point of the source. You never know when inspiration will strike causing you to need a black outline for a project. So download and print these outlines and store them with your crafting supplies. (Double Parabolic Reflective Wave Guide) device geometrically based entirely on precise mathematic calculations to take a circular planar (flat) wavefront emitted by the source at its input (e.g. Butterfly Outlines The black butterfly outlines add a decorative element to bulletin boards, and they are so much fun for kids to decorate. The high frequency section of the Butterfly system is equipped with a 3” (1.41” throat) compression driver coupled with a D.P.R.W.G. This original design solution favours the optimum coupling of array elements up to the highest frequencies, keeping the distance between the sources as short as possible and at the same time providing them with a continuous loading ‘baffle’. the cabinet has an unmistakable shape which brings to mind the butterfly from which it takes its name, thanks to the triangular opening in the upper and lower “sides”. 483 Hi-Pack is the Butterfly system’s element for mid-low, mid and high frequency reproduction.
