It's the most compact model in the Motion Foundation range, and it takes the thin-film tweeter technology the brand built its reputation on and brings it down to a price and a footprint that make sense for ordinary rooms. The result is a small bookshelf speaker that sounds far bigger and far more refined than its size suggests, finished here in a clean Satin White that suits modern, light interiors.\u003c\/p\u003e\n\u003ch4 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Folded Motion Tweeter Advantage\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe heart of the B1 is the Gen2 Obsidian Folded Motion Tweeter S. Instead of a conventional dome, it uses a pleated thin-film diaphragm that packs a large radiating surface into a tiny, lightweight panel. Because that panel barely has to move to produce sound, it responds with a speed and precision a normal tweeter struggles to match, which is exactly why MartinLogan speakers are known for their airy, detailed treble. On the B1 it reproduces fine texture in voices, strings and cymbals with a clarity that genuinely surprises people at this price.\u003c\/p\u003e\n\u003ch4 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eControlled Dispersion for Consistent Sound\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePaired with the tweeter is a Folded Motion Waveguide that shapes how the high frequencies spread into the room. It widens and evens out the sweet spot so the detail holds up across a broader seating area, and it reduces the early reflections off nearby surfaces that can smear and dull the sound. In practice that means the B1 sounds clean and focused without demanding that you sit in one perfect chair to hear it at its best.\u003c\/p\u003e\n\u003ch4 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA Driver That Keeps Up\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eHandling the midrange and bass is a 5.5\" aluminium cone driver built on a cast aluminium basket with a non-resonant sealed chamber. The stiff aluminium cone resists flexing, so notes stay clear and controlled rather than soft or muddy, and the construction is trickle-down engineering from MartinLogan's higher Motion and Motion XT ranges. The B1 reaches down to 48Hz, which is plenty for music in a smaller room, and it pairs beautifully with a subwoofer when you want full home-cinema weight underneath it.\u003c\/p\u003e\n\u003ch4 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEasy to Drive and Easy to Place\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWith a sensitivity of 89dB and a recommended amplifier range of 15 to 100 watts, the B1 is happy with modest integrated amplifiers and AV receivers alike, so you don't need exotic electronics to get the best from it. Connection is via quality five-way binding posts. For a tidy, stable setup the cabinet is threaded to work with MartinLogan's STAND25 stands, and the compact size means it sits comfortably on a shelf, sideboard or desk where a larger speaker simply wouldn't fit.\u003c\/p\u003e\n\u003ch4 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA Foundation You Can Build On\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSold individually so you can configure exactly the system you need, the B1 works as a refined stereo pair in a study or second room, as rear channels in a larger MartinLogan surround setup, or as the starting point for a hi-fi system you grow over time. It is, as the name suggests, a foundation, and a remarkably musical one.\u003c\/p\u003e\n\u003ch4 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSpecifications\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]\"\u003eType: 2-way passive bookshelf speaker \u003cbr\u003eCabinet: Rear ported (bass reflex) \u003cbr\u003eHigh-frequency driver: 0.94\" x 1\" Gen2 Obsidian Folded Motion Tweeter S, 3.5 sq in diaphragm \u003cbr\u003eWaveguide: Folded Motion Waveguide \u003cbr\u003eMid-bass driver: 5.5\" aluminium cone, cast aluminium basket, non-resonant sealed chamber \u003cbr\u003eFrequency response: 48Hz to 23kHz, plus\/minus 3dB \u003cbr\u003eCrossover frequency: 3,400Hz Sensitivity: 89dB Impedance: 5 ohms (compatible with 4, 6 or 8 ohm amplifiers) \u003cbr\u003eRecommended amplifier power: 15 to 100 watts \u003cbr\u003eTweeter dispersion (H x V): 90 degrees x 90 degrees \u003cbr\u003eConnectors: Five-way binding posts (non bi-wire) Stand compatibility: \u003cbr\u003eThreaded for MartinLogan STAND25 \u003cbr\u003eFinish: Satin White Weight: 5.23kg (11.5 lb) each\u003c\/p\u003e","brand":"Martin Logan","offers":[{"title":"Default Title","offer_id":48217169068277,"sku":"ZFB1SW","price":11190.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/1731\/0453\/files\/ZFB1SW_0j3m.webp?v=1780301224","url":"https:\/\/shop.smartspaces.co.za\/products\/m-logan-foundation-b1-satinwhite","provider":"Smart Spaces Shop","version":"1.0","type":"link"}
