    The HD1040 has been designed for use in high quality audio systems. With a 1-inch exit throat, the HD1040 has been developed to match the XT1086 constant directivity horn.
    Equipped with unique Phase Plug architecture (Patent n. WO 2004/040942), the HD1040 has been designed to give high level manufacturing consistency and smooth coherent wave front at the horn entrance across the whole working frequency range. The phase plug with its short openings and high flare rate value assures low distortion and demonstrates remarkable improvements in mid-high frequency reproduction.
    The greatest innovation in the HD1040 is the new diaphragm assembly made from proprietary treated Polyethylene material. Thanks to its superior diaphragm dimensional stability (160°C), the HD1040 is able to maintain constant behaviour during its whole working life. Moreover, this particular material with its very high value of elasticity modulus, (50% more than standard Mylar and 100% more than polyimide film) is capable of superior transient and intermodulation distortion response. The flat suspension shape is designed to maintain low stiffness and low mid band distortion and response.
    An edge-wound aluminum voice coil wound on proprietary treated Nomex completes the diaphragm assembly. Thanks to its physical properties, the proprietary treated Nomex former shows a 30% higher value of tensile elongation at a working operative temperature, (200°C) when compared to Kapton. This feature enables proper energy transfer control from the voice coil to the dome in real working conditions. Moreover, this proprietary former material is suitable for use in damp and wet environments.
    The HD1040’s powerful ceramic magnet assembly has been designed to obtain 16KGauss in the gap within a compact ferrite motor structure.
