The Kappalite 3010LF-4 from Eminence is a new direction in professional subwoofer driver design. Eminence chose a neodymium motor, known for maximum BL product (magnet energy) while remaining lightweight, a truncated die-cast aluminum basket for rigidity, vented pole piece (for reduced power compression), and a treated paper cone with cloth accordion surround.
