STUDIO

The drive units at the heart of every new Turbosound enclosure arebuilt by Precision Devices Ltd.A company specifically established by our parent company, EdgeTechnology Group, to develop drive units with unsurpassed reliability and audioperformance.DEVELOPING THE CONE AND COIL.Particular attention has been paid to designing each cone's profile andmaterials for its intended application.The voice coils are wound with pure copper for long term strength andreliability, coated with high temperature enamel, onto an epoxy resin -impregnated woven fibreglass former.The whole assembly is cured at high temperature to give it acompletely rigid, integrated structure for greater strength and energytransmission abilities.AN ADVANCED MAGNET ASSEMBLY.The magnet assemblies are of the traditional iron and ceramic'sandwich' type. The difference lies in our attention to detail and the quality ofmaterials.Top quality low- carbon steel is machined to very fine tolerances tomaximise contact between plates. And as tight a magnetic gap as possible inturn gives greater magnetic power and increased cooling for the coil. (In ourlarger drivers, we also bolt the parts together for extra strength).Finally, the loudspeakers' frame designs are based on the soundest ofengineering principles, with generous use of die -cast aluminium alloy to ensuretheir indestructibility on the road. In fact, our frames weigh twice as much asmost other manufacturers'.Guaranteeing that even under massive physical shock, the assemblywon't suffer.ATTENTION TO DETAIL.All this attention to detail means that every step in the manufacturingchain is designed to enhance our enclosures' performance.Finally, the components come together in a modular assembly process,with testing at every step, before being fitted into enclosures that have beenbuilt with equal precision.The result is a finished product that produces accurate, natural soundsimply through the precise matching of its components. Which means that,more than ever, there is no need for external electronic compensation.So that's a breakdown of what Precision Devices will mean to you.And what makes Turbosound enclosures so exceptionally reliable.OTurbosound4`ONCE HEARD NEVER FORGOTTENTURBOSOUND LIMITED, STAR ROAD, PARTRIDGE GREEN, WEST SUSSEX RH13 5EZ.
