A 9 mm M9-R dynamic driver and two balanced armatures form the low-frequency system, three further armatures handle the midrange, and two MP-2 planar drivers plus four electrostatic tweeters complete the upper section.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12 drivers per side in a quadbrid configuration.\u003c\/li\u003e\n\u003cli\u003e1 VOLK M9-R 9 mm dynamic driver.\u003c\/li\u003e\n\u003cli\u003e5 Sonion balanced-armature drivers.\u003c\/li\u003e\n\u003cli\u003e2 VOLK MP-2 planar-magnetic drivers.\u003c\/li\u003e\n\u003cli\u003eUpper treble section based on 4 Sonion electrostatic tweeters.\u003c\/li\u003e\n\u003cli\u003eProprietary six-way crossover.\u003c\/li\u003e\n\u003cli\u003e10 Hz-45 kHz frequency response and 7.17-ohm impedance at 1 kHz.\u003c\/li\u003e\n\u003cli\u003e4.4 mm cable using 5N copper, 4N silver and 24K gold conductors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTwo hybrid systems at opposite ends of the spectrum\u003c\/h3\u003e\n\u003cp\u003eIn the low range, the LF-H system combines the M9-R dynamic unit with two armatures in a chamber designed to control pressure and phase. At the opposite end, HF-H joins two planar drivers with four electrostatics: the planars manage the upper transition while the EST array extends response to 45 kHz.\u003c\/p\u003e\n\u003ch3\u003eAluminium, steel and sapphire crystal\u003c\/h3\u003e\n\u003cp\u003eThe chassis is machined from 6061-T6 aluminium, with a 316 stainless-steel faceplate frame and a 9H sapphire-crystal panel. The vent and acoustic-path architecture is part of the tuning, intended to stabilise diaphragm behaviour while reducing internal pressure build-up and unwanted resonances.\u003c\/p\u003e\n\u003ch3\u003eWhere it sits in the range\u003c\/h3\u003e\n\u003cp\u003eCompared with Novus, Stella omits bone conduction and uses a different transducer balance with greater emphasis on planar drivers. XIO reduces the driver count and introduces 64 Audio apex, tia and LID technologies, while Luna relies on a single planar unit. Stella suits listeners who want an elaborate multi-driver design with a distinctly different architecture from Novus. Its 103.8 dB sensitivity and 7.17-ohm impedance suit high-quality DAPs with low output impedance, without demanding unusually high voltage from the connected amplifier or player.\u003c\/p\u003e\n","brand":"Astell \u0026 Kern","offers":[{"title":"Default Title","offer_id":58600246444376,"sku":null,"price":4999.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5278\/7645\/files\/astell-kern-stella-front-dfbkb.jpg?v=1790777011","url":"https:\/\/videosell.it\/en\/products\/astell-kern-stella","provider":"Videosell store","version":"1.0","type":"link"}
