The outcome is a response that reaches down to 42 Hz (up to 23 kHz, within ±3 dB) and a sensitivity of 90 dB. It can go on a shelf or on a stand, and it is compatible with MartinLogan's STAND25.\u003c\/p\u003e\n\u003cp\u003eThe two-way crossover hands over at 3,800 Hz. Below that point the work is done by a woofer with a Unibody aluminium cone, the same approach the brand uses in its Motion XT and Motion ranges, with a stamped steel basket and an asymmetrical chamber devised to counter resonances. The cabinet is a bass reflex type venting at the rear. Impedance is 5 ohms and the recommended amplifier rating runs from 15 to 100 watts.\u003c\/p\u003e\n\u003cp\u003eAbove 3,800 Hz the Folded Motion S Gen2 tweeter, in Obsidian form, takes over. It uses a folded thin film that provides 22.6 cm² of surface while occupying only 24 x 25 mm: it is light, moves very little and therefore responds promptly. The waveguide that houses it spreads the output over 90° both horizontally and vertically, so the sound stays even for listeners seated off centre.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003eType: two-way stand or shelf speaker, reflex-loaded at the rear\u003c\/li\u003e\u003cli\u003eFrequency range: 42 Hz to 23 kHz, ±3 dB\u003c\/li\u003e\u003cli\u003eImpedance: 5 ohms\u003c\/li\u003e\u003cli\u003eSensitivity: 90 dB\u003c\/li\u003e\u003cli\u003eSuggested amplifier: 15 to 100 W\u003c\/li\u003e\u003cli\u003eCrossover point: 3,800 Hz\u003c\/li\u003e\u003cli\u003eTweeter: 24 x 25 mm Folded Motion S Gen2, 22.6 cm² diaphragm\u003c\/li\u003e\u003cli\u003eTweeter coverage: 90° horizontally and vertically\u003c\/li\u003e\u003cli\u003eWoofer: 16.5 cm Unibody aluminium cone, stamped steel basket\u003c\/li\u003e\u003cli\u003eCabinet: bass reflex with rear port\u003c\/li\u003e\u003cli\u003eTerminals: five-way posts, no bi-wiring\u003c\/li\u003e\u003cli\u003eGrille: magnetic cloth grille over the woofer\u003c\/li\u003e\u003cli\u003eMatching stand: STAND25\u003c\/li\u003e\u003cli\u003eSize (H x W x D): 38.1 x 19.7 x 29.2 cm\u003c\/li\u003e\u003cli\u003eWeight: 6.8 kg\u003c\/li\u003e\u003cli\u003eSupplied: sold as a pair\u003c\/li\u003e\u003cli\u003eFinishes: black, white, walnut\u003c\/li\u003e\u003c\/ul\u003e","brand":"Martin Logan","offers":[{"title":"Nero","offer_id":47927313236312,"sku":"10606429238","price":897.73,"currency_code":"EUR","in_stock":true},{"title":"Bianco","offer_id":47927313269080,"sku":"10606429234","price":897.73,"currency_code":"EUR","in_stock":true},{"title":"Noce","offer_id":47927313301848,"sku":"10606429338","price":897.73,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5278\/7645\/files\/MartinLogan_Foundation-B2_black_01_ebcda507-6b38-4cc4-8c8e-69b41c0a96ad.jpg?v=1710148769","url":"https:\/\/videosell.eu\/products\/martinlogan-foundation-b2","provider":"Videosell store","version":"1.0","type":"link"}
