After the South African gems from Vivid Audio, my virtual audio journey left me in Lublin/Poland at the doors of the Autotech conglomerate. Established in the early 2000s, they deal with various productions of automotive parts, motorbike trailers, housings for electric vehicles – and yes, loudspeakers. The guy behind this unusual panoply of products is Lukasz Lewandowski, founder and chief designer. The division in charge of audio has simply been named hORNS since their core business is the manufacture of horns and wave guides (another name for very shallow horns) which are disseminated as kits or as complete loudspeakers. DIY in fact was hORNS’ very first market.
Wave guides and horns help to match the acoustic impedance of compression drivers which produce a highly concentrated sound to the impedance of the room which dispersed that sound. They act as a kind of acoustic transformer and came standard with the very first gramophones. Lewandowski offers a large choice of horn types but mainly promotes Jean-Michel Le Cléac’h (JMLC) hyperbolic horns and SEOS hybrid forms (Super Elliptical Oblate Spheroid) which are slightly less intrusive and offer wider horizontal dispersion. But he can meet most customization requests with many different sorts of horn shapes.
hORNS’ specialty is poly-glass as the overlap with Autotech’s automotive glass-fiber productions. The company manufactures parts from epoxy and polyester laminates as well as with RIM tech (reaction injection molding). They specialize in developing concepts, designs, build patterns and molds, manufacturing finished parts as well as conduct R&D of prototype parts. Autotech use CAD & CAM for their production as well as 3D laser scanners and CNC planer mills and are experienced also in more traditional mold making. Autotech can manufacture in rigid polyurethane foam (PUR) with injection molding. We are suddenly not that far removed from the gestation process of my Vivid G1 where their enclosures are concerned.
