Loudspeaker designers can look forward to a couple of exciting materials that have been in stealth mode but are about to step into the spotlight. A lightweight military aviation-grade nanocomposite from Alpine Advanced Materials, HX5 may be an alternative to beryllium and high-performance aluminum alloys used in woofer, midrange, and full-range cones. Compared to aluminum, cones can be made at half the weight with comparable strength. This article was originally published in audioXpress, January 2022.
