X Diamond Mk II

The Estelon X Diamond Mk II is a three-way loudspeaker manufactured by Estelon, using custom-designed Accuton drivers: a 280 mm ceramic-sandwich woofer, 173 mm ceramic mid-woofer, and 25 mm diamond inverted-dome tweeter. Its cabinet is made from a proprietary marble-based composite with no flat or parallel surfaces, separate driver chambers, a bass-reflex woofer enclosure, and an isolated tweeter chamber. The speaker uses a second-order crossover at 77 Hz and 2 kHz with Mundorf and Jantzen capacitors, Goertz and Mundorf inductors, Kubala-Sosna internal cabling, and star-wired flat-foil direct coupling; it measures 450 mm wide by 640 mm deep and weighs 86 kg per piece.
