A reference overview of Jensen’s Bass Ultraflex enclosures from Jensen Hi-Fi Speaker Systems (1956), treating the 15″, 12″, and 8″ cabinets as one scaled design family defined by fixed internal volume and duct geometry.
In 1982, Jacques Mahul explored how the classic Onken bass-reflex principle could be reduced in scale without losing musical integrity. This article—faithfully translated from L’Audiophile—details the Mini-Onken enclosure, its theoretical foundations, precise calculations, and the development of the Focal 10C01, offering rare insight into the transition from Japanese Onken designs to what would later become Focal/JMLab.
