{"product_id":"piega-coax-411-gen2-bookshelf-loudspeakers","title":"Piega Coax 411 Gen2 Bookshelf 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 Coax 411 Gen2 is the bookshelf expression of the Coax architecture, and it is the smallest Piega in which every important sonic decision of the larger floorstanders is preserved intact. The C112+ coaxial ribbon module — the same driver used in the 611 Gen2 — handles midrange and treble as a single point source, with the imaging precision and lateral coherence that only a coaxial design delivers. A single 160 mm UHQD woofer in the extruded aluminum cabinet covers the bass to 35 Hz, which is remarkable for a speaker of this size and reflects the efficiency of Piega's sealed-cabinet alignment with Tension Improve Module 2 reinforcement. On the right stands, in a properly treated room, the Coax 411 Gen2 produces a soundstage and image density that listeners reflexively associate with much larger and more expensive floorstanders. For desktop near-field, second-system, or a deliberate small-room main pair, this is the rare bookshelf that competes against the flagship-tier presentation rather than apologizing for its size.\u003c\/p\u003e \u003cp\u003eFor owners who want the Coax 411 in something beyond the standard aluminum, black, or white finishes, the Coax Excellence program offers eight additional colors hand-finished in Switzerland: Blue Lagoon, Misty Green, Shiny Ash, Desert Gold, Bordeaux Red, Havana Tobacco, Autumn Bronze, and Alpine Stone.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSeries:\u003c\/strong\u003e Coax Gen2\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Three-way bookshelf with coaxial ribbon module\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDrivers:\u003c\/strong\u003e 1 × 160 mm UHQD woofer; 1 × C112+ coaxial ribbon driver\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFrequency Range:\u003c\/strong\u003e 35 Hz – 50 kHz\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 90 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 – 200 watts\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDimensions (H × W × D):\u003c\/strong\u003e 17.7\" × 8.3\" × 12.2\" (45 × 21 × 31 cm)\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 55 lb (25 kg) each\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCabinet:\u003c\/strong\u003e Extruded aluminum with Tension Improve Module 2 (TIM2)\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eStandard Finishes:\u003c\/strong\u003e Silver polished aluminum, Black anodized aluminum, White lacquer\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCoax Excellence Finishes (optional upgrade):\u003c\/strong\u003e Blue Lagoon, Misty Green, Shiny Ash, Desert Gold, Bordeaux Red, Havana Tobacco, Autumn Bronze, Alpine Stone\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eBuilt by hand in Horgen, Switzerland.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Piega","offers":[{"title":"Silver polished aluminum","offer_id":48790580756699,"sku":null,"price":11995.0,"currency_code":"USD","in_stock":true},{"title":"Black anodized aluminum","offer_id":48790580789467,"sku":null,"price":11995.0,"currency_code":"USD","in_stock":true},{"title":"White lacquer","offer_id":48790580822235,"sku":null,"price":11995.0,"currency_code":"USD","in_stock":true},{"title":"Blue Lagoon (Excellence)","offer_id":48790580855003,"sku":null,"price":14495.0,"currency_code":"USD","in_stock":true},{"title":"Misty Green (Excellence)","offer_id":48790580887771,"sku":null,"price":14495.0,"currency_code":"USD","in_stock":true},{"title":"Shiny Ash (Excellence)","offer_id":48790580920539,"sku":null,"price":14495.0,"currency_code":"USD","in_stock":true},{"title":"Desert Gold (Excellence)","offer_id":48790580953307,"sku":null,"price":14495.0,"currency_code":"USD","in_stock":true},{"title":"Bordeaux Red (Excellence)","offer_id":48790580986075,"sku":null,"price":14495.0,"currency_code":"USD","in_stock":true},{"title":"Havana Tobacco (Excellence)","offer_id":48790581018843,"sku":null,"price":14495.0,"currency_code":"USD","in_stock":true},{"title":"Autumn Bronze (Excellence)","offer_id":48790581051611,"sku":null,"price":14495.0,"currency_code":"USD","in_stock":true},{"title":"Alpine Stone (Excellence)","offer_id":48790581084379,"sku":null,"price":14495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1363\/6553\/files\/Coax-411-Front-silver-2.png?v=1779242754","url":"https:\/\/almaaudio.com\/products\/piega-coax-411-gen2-bookshelf-loudspeakers","provider":"Alma Music and Audio","version":"1.0","type":"link"}
