Actual official professional footage of the Joachim-Gerhard-Collection Darling Master 4 speaker with Purifi midrange, 1″ Bliesma Beryllium tweeter and passive radiator on the rear. Cabinet is 40mm solid smoked oak, black glass.
The surround geometry of this woofer allows the cone to move seamlessly. Whether inward or outward, it always stays in the same area. This reduces distortion as this woofer has an extremely long excursion (linear Xmax +/- 8.5mm).
