KEF labyrinth

Get lost! – This geometry resembling a medieval labyrinth garden is KEF's newest energy absorption tech slated to appear in a range of future products. Rather than rely on wool/foam-type stuffing and filler to deal with driver rear waves otherwise running amok inside a box, this mathematically derived geometry claims to capture 99% of a driver's rear energy. If so, that's far more efficient than existing solutions. Of course Boenicke speakers have been doing something similar for years simply executed in solid wood across their entire cabinets.
