{"product_id":"borr-c1","title":"Borresen C1 Loudspeakers","description":"\u003cp\u003eDeveloped by Michael Børresen and Flemming Erik Rasmussen, the Børresen C1 is a reference 2-way stand-mount loudspeaker designed for high-end stereo systems in small to medium-sized listening spaces. The cabinet is constructed from dense hardwood laminates reinforced with 1mm carbon fiber side panels for maximum acoustic rigidity and resonance control. It comes complete with custom-designed matching stands made from non-magnetic composite materials, equipped with integrated Ansuz Darkz S2t resonance control decouplers to isolate the speaker system from floor vibrations.\u003c\/p\u003e\n\n\u003cp\u003eIts driver complement combines an ultralight RP94 planar ribbon tweeter (0.01g moving mass, 94 dB efficiency) with a custom 5-inch Børresen DCC5 Neo bass\/midrange driver. The DCC5 Neo driver utilizes a tri-layer composite membrane—an aramid honeycomb core sandwiched between carbon fiber skins—to deliver low distortion and rapid transient dynamics. Managing frequency distribution is a phase-coherent serial crossover network engineered to preserve phase alignment and ensure seamless driver integration.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eBørresen DCC5 Neo Driver:\u003c\/strong\u003e Custom 5-inch bass\/midrange driver featuring a powerful neodymium magnet structure for precise dynamics and low distortion.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003e3-Layer Composite Membrane:\u003c\/strong\u003e Diaphragm constructed with an aramid honeycomb core between carbon fiber skins for high stiffness and minimal energy storage.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eRP94 Planar Ribbon Tweeter:\u003c\/strong\u003e Features an ultra-light 0.01-gram moving mass and 94 dB efficiency for extended, transformer-free high-frequency response up to 50 kHz.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eResonance-Controlled Enclosure:\u003c\/strong\u003e Dense hardwood laminate cabinet clad in 1mm carbon fiber side panels to suppress structural vibrations.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003ePhase-Coherent Serial Crossover:\u003c\/strong\u003e Serial crossover topology ensures drivers remain in phase alignment for cohesive imaging and realistic spatial presentation.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eCustom Matching Stands \u0026amp; Darkz S2t Decoupling:\u003c\/strong\u003e Includes dedicated non-magnetic composite stands equipped with integrated Ansuz Darkz S2t resonance control devices for mechanical decoupling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\n\n\u003ctable style=\"width: 100%;\"\u003e\n\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpeaker Type\u003c\/td\u003e\n      \u003ctd\u003e2-Way Stand-Mount \/ Bookshelf Loudspeaker with Dedicated Stands\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHigh Frequency Driver\u003c\/td\u003e\n      \u003ctd\u003e1x Børresen RP94 Planar Ribbon Tweeter (0.01g Moving Mass)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBass \/ Midrange Driver\u003c\/td\u003e\n      \u003ctd\u003e1x 5\" Børresen DCC5 Neo Driver\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFrequency Response\u003c\/td\u003e\n      \u003ctd\u003e45 Hz – 50,000 Hz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSensitivity\u003c\/td\u003e\n      \u003ctd\u003e87 dB \/ 1W\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNominal Impedance\u003c\/td\u003e\n      \u003ctd\u003e\u0026gt; 6 Ω\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Amplifier Power\u003c\/td\u003e\n      \u003ctd\u003e\u0026gt; 50 W\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eEnclosure Material\u003c\/td\u003e\n      \u003ctd\u003eDense Hardwood Laminate with 1mm Carbon Fiber Side Panels\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStand \u0026amp; Isolation System\u003c\/td\u003e\n      \u003ctd\u003eNon-Magnetic Composite Stands with Integrated Ansuz Darkz S2t Decouplers\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFinish Options\u003c\/td\u003e\n      \u003ctd\u003eBlack Piano Lacquer \/ White Piano Lacquer\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions (Speaker Unit)\u003c\/td\u003e\n      \u003ctd\u003e469 x 204 x 430 mm (H x W x D)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions (With Stand)\u003c\/td\u003e\n      \u003ctd\u003e705 x 297 x 433 mm (H x W x D)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight (Speaker Unit)\u003c\/td\u003e\n      \u003ctd\u003e18 kg per speaker\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight (With Stand)\u003c\/td\u003e\n      \u003ctd\u003e24.5 kg per speaker\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Borresen","offers":[{"title":"Gloss Black","offer_id":52739984589066,"sku":"BORRESEN-9116","price":14995.0,"currency_code":"GBP","in_stock":true},{"title":"Gloss White","offer_id":52739984621834,"sku":"BORRESEN-9117","price":14995.0,"currency_code":"GBP","in_stock":true},{"title":"Please Select:","offer_id":52739984654602,"sku":"BORRESEN-9118","price":14995.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/3283\/6618\/files\/borresen-c1-loudspeakers-50874-p.png?v=1773933909","url":"https:\/\/audioemotion.co.uk\/products\/borr-c1","provider":"Audio Emotion Limited","version":"1.0","type":"link"}
