AUDAX HM130Z0 - Midrange 5.25"  HDA cone - 8 ohm

HD-A (High Definition Aerogel) cone. Non resonant die cast chassis. Ventilated chassis under spider. High loss rubber suspension. Edgewound, flat copper wire. Kapton Voice Coil Former. High loss phase plug. Gold plated terminals.

High Definition Aerogel represents a true breakthrough in loudspeaker cone technology, surpassing all conventional materials being used today. Through an extraordinary combination of newly developed materials and processes, audax has created an innovative composite membrane whose properties are very close to ideal for making loudspeaker diaphragms. Ultra light, extermely rigid and maximized internal damping. This no-compromise cone is based on a totally controlled matrix of acrylic polymer gel in which an optimized proportion of Carbon and Kevlar fibers are embedded. An exclusive, proprietary process acts to perfectly align the fibers alon the polymer chain. The procedure allows total control over the contour and weight of the cone, while making it possible to vary the thickness of the membrane along the profile.

This 5.25 inch Midrange driver was designed for top range, no-compromise high end 3 or 4-way systems. It features a die cast Zamack chassis with unobstructed venting for enhanced transient response and a non resonant phase plug for high end frequency equalization. High power handling resultats from the flat, edgewound copper coil mounted onto a fiberglass reinforced Kapton voice coil former. Unequaled definition is achieved over a wide spectrum of frequencies and dynamic ranges while retaining a neutral tonal balance with precise and detailed imaging.
