Hand drawn ornamental butterfly outline illustration with decorative ornaments. 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. Download 31904 Butterfly Outline Stock Illustrations, Vectors & Clipart. The children were given an outline of a stereotypical butterfly, and could choose from pink, blue and yellow screwed-up tissue paper, and they filled in the. 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. (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. 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.
