{"product_id":"piega-master-line-source-mkii-ltd-loudspeakers","title":"Piega Master Line Source MKII LTD Loudspeakers","description":"\u003cp\u003ePiega is a Swiss loudspeaker maker that has spent four decades doing one thing better than almost anyone else: building ribbon transducers and mating them to extruded aluminum cabinets that disappear from the music. The company was founded in 1986 on Lake Zurich, and every speaker that wears the Piega badge — from the entry models to the limited-edition flagships — is still assembled by hand in Horgen, Switzerland. The ribbon-tweeter architecture that defines the brand is not borrowed technology. Piega develops and manufactures its own ribbon drivers in-house, including the coaxial ribbon module that places the midrange and treble at a single physical point and resolves the time-alignment problem that conventional two-way and three-way crossovers can only approximate. The cabinets are pulled from a single piece of extruded aircraft-grade aluminum, internally damped with Piega's Tension Improve Module to remove panel resonance before it can color the sound. The result is a presentation that listeners describe in the same vocabulary year after year: fast, clean, dimensionally precise, and free of the boxy signature that almost every traditional cabinet imposes on the music.\u003c\/p\u003e \u003cp\u003eThe Master Line Source MKII LTD is Piega's statement. It is a multi-cabinet, three-way dipole line-source system built around twenty-four LDR 2642 MKII ribbon tweeters arranged in front-firing and rear-firing arrays, nine MLS 110-100 dipole midrange ribbons, and a pair of dedicated bass towers each loaded with six 220 mm UHQD woofers. The line-source principle delivers a coherent cylindrical wavefront rather than the spherical radiation pattern of point-source speakers, which preserves frequency response and dynamic contrast across an unusually long listening distance — the speaker plays as cleanly at twenty feet as at six. The dipole midrange and treble arrays radiate equally to the front and rear of the listener, producing a soundstage that is genuinely three-dimensional rather than the flat proscenium most conventional speakers project. Each MLS MKII LTD pair is built to order over a period of weeks by a single senior Piega technician. Production is intentionally limited; total system weight is approximately 600 kilograms across the four cabinets.\u003c\/p\u003e \u003cp\u003eThe MKII LTD reflects a specific philosophical position about what a flagship loudspeaker should be. It is not the most expensive Piega builds — it is the most resolved expression of the line-source principle Piega has ever produced, in the trim level its engineers chose when they were no longer constrained by anything but the physics of the medium. Buyers at this level are not comparison-shopping against other flagships on a spec sheet; they are deciding which company's chief engineer they trust to define the upper limit. The answer Piega offers is documented in 38 years of continuous refinement of one fundamental idea.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSeries:\u003c\/strong\u003e Master Line Source\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Three-way dipole line-source system, multi-cabinet (mid\/high panels + bass towers)\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDrivers:\u003c\/strong\u003e 24 × LDR 2642 MKII ribbon tweeters (12 front-firing, 12 rear-firing); 9 × MLS 110-100 dipole midrange ribbons; 6 × 220 mm UHQD bass drivers per side\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFrequency Range:\u003c\/strong\u003e 18 Hz – 50 kHz\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 94 dB\/W\/m\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eImpedance:\u003c\/strong\u003e 4 ohms\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eRecommended Amplification:\u003c\/strong\u003e 20 – 1000 watts\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDimensions (Mid\/High Panel):\u003c\/strong\u003e 70\" H × 17.3\" W × 2\" D (178 × 44 × 5 cm)\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDimensions (Bass Tower):\u003c\/strong\u003e 70\" H × 15\" W × 23.6\" D (178 × 38 × 60 cm)\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSystem Weight:\u003c\/strong\u003e approximately 1,323 lb (600 kg) total across all cabinets\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFinishes:\u003c\/strong\u003e Aluminum (polished aluminium cabinet with silver cover) or Black (black anodised cabinet with black cover)\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eBuilt by hand in Horgen, Switzerland.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Piega","offers":[{"title":"Aluminum","offer_id":48790579708123,"sku":null,"price":390000.0,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":48790579740891,"sku":null,"price":390000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1363\/6553\/files\/PIEGA-MLS-MK-II-cover-600x1000-1.png?v=1779242728","url":"https:\/\/almaaudio.com\/products\/piega-master-line-source-mkii-ltd-loudspeakers","provider":"Alma Music and Audio","version":"1.0","type":"link"}
