The perfect speaker for any composition. \u003c\/h4\u003e\n\u003cp\u003eBorn out of the increasingly demanding challenges of modern automobile technology and the HELIX-typical pursuit of intelligent solutions, we made the progressive redesign of proven universal speaker systems our mission. The result: our innovative \u003ca title=\"HELIX COMPOSE\" href=\"https:\/\/www.audiotec-fischer.de\/en\/compose\/\"\u003eHELIX COMPOSE platform\u003c\/a\u003e that, according to the motto \"developed inside the vehicle, for the vehicle\", combines classic universal speakers with the advantages of vehicle-specific systems. Innovative materials and the latest technologies paired with smart, practical engineering – the best of both worlds in harmony: high efficiency, fantastic sound quality and enormous dynamics that fit in any vehicle. HELIX COMPOSE – universal speakers evolved.\u003c\/p\u003e\n\u003ch4\u003eThe Sound Sensation for sophisticated music lovers \u003c\/h4\u003e\n\u003cp\u003eThe HELIX COMPOSE \u003ca title=\"i5\" href=\"https:\/\/www.audiotec-fischer.de\/en\/compose\/series\/#i5-Serie\"\u003ei5\u003c\/a\u003e series is the link between \u003ca title=\"COMPOSE i7\" href=\"https:\/\/www.audiotec-fischer.de\/en\/compose\/series\/#i7-Serie\"\u003ei7\u003c\/a\u003e and \u003ca title=\"COMPOSE i3\" href=\"https:\/\/www.audiotec-fischer.de\/en\/compose\/series\/#i3-Serie\"\u003ei3\u003c\/a\u003e, created for sophisticated music lovers with a sparked ambition for a true hi-fi experience. A lovechild of phenomenal sound and unmatched practicality: Developed with the vision of unique speaker highlights that are also true problem solvers. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time. In addition, we implemented our COMPOSE-exclusive mechanical technologies that offer unbeatable practical benefits. \u003c\/p\u003e\n\u003ch4\u003ePrecise broadband performance for demanding center-channel applications\u003c\/h4\u003e\n\u003cp\u003eThe Ci5 M80FM-D3 CTR has been engineered as an audiophile broadband driver for center-channel applications in high-quality multi-way systems. Its wide linear frequency range, high power handling and generous linear excursion enable exceptionally clear, natural and dynamic sound and speech reproduction – even at high listening levels.\u003cbr\u003eA key feature of the Ci5 M80FM-D3 CTR is its separate voice coil for supporting the vehicle’s automatic emergency call function. While one voice coil carries the music signal, the second provides a separate connection for the factory eCall system. This allows the original center speaker to be replaced with a high-quality audio solution without compromising this essential vehicle function. \u003cbr\u003eThanks to its significantly reduced outer diameter compared with conventional 3 inch \/ 80 mm drivers, the Ci5 M80FM-D3 CTR also offers outstanding integration flexibility – for example in tight factory mounting locations using FlexMount technology, without compromising the cone area. This makes it perfectly suited for demanding multi-way systems, DSP-optimized setups or vehicles where precise sound reproduction and a compact form factor are equally important. In line with its intended use as a center speaker, the Ci5 M80FM-D3 CTR is supplied as a single loudspeaker.\u003c\/p\u003e\n\u003ch4\u003eSophisticated engineering for dynamics, efficiency and low distortion\u003c\/h4\u003e\n\u003cp\u003eThe remarkable performance of the Ci5 M80FM-D3 CTR is the result of a carefully coordinated combination of materials and mechanical design. Its silicon-coated paper cone provides high internal damping, an exceptionally natural and accurate sound reproduction and suppresses unwanted resonance frequencies. The particularly narrow surround structure, whose inward-folded surround edge is bonded in a complex manufacturing process, works in conjunction with the innovative magnet system to allow for a large linear excursion – a key factor behind the driver’s high power handling and low-distortion behavior, ensuring confident performance even at elevated listening levels. \u003cbr\u003eFurthermore, it noticeably reduces the outer diameter while increasing the effective cone area. The result is a compact form factor paired with high acoustic efficiency. Completing the design is an aluminum dustcap that enhances upper-midrange performance, along with a powerful push-pull neodymium magnet system that combines high efficiency with minimal distortion – contributing significantly to the precise, dynamic sonic character of the Ci5 M80FM-D3 CTR. \u003c\/p\u003e\n\u003ch4\u003eHigh efficiency\u003c\/h4\u003e\n\u003cp\u003eHELIX COMPOSE equals smart engineering and accordingly implements highly efficient 3 Ohm technology, that perfectly harmonizes with all \u003ca title=\"Amplifiers by HELIX\" href=\"https:\/\/www.audiotec-fischer.de\/en\/helix\/amplifiers\/\"\u003eHELIX\u003c\/a\u003e and \u003ca title=\"Amplifiers by MATCH\" href=\"https:\/\/www.audiotec-fischer.de\/en\/match\/amplifiers\/\"\u003eMATCH amplifiers\u003c\/a\u003e and at the same time allows a clearly perceptible plus in efficiency and maximum sound pressure.\u003c\/p\u003e\n\u003ch4\u003eHigh-tech polymer basket\u003c\/h4\u003e\n\u003cp\u003eThe Ci5 M80FM-D3 CTR speaker basket is made of a high-tech polymer composite, which has been additionally reinforced with glass spheres. The result: maximum stability with minimal self-resonance, while also eliminating flux modulation of the magnetic system and maximum resistance to thermal influences. Last but not least, this allows for much more compact basket dimensions and thus simplified installations in cramped installation conditions.\u003c\/p\u003e\n\u003ch4\u003eFlexMount80 – Universal meets car-specific\u003c\/h4\u003e\n\u003cp\u003eFlexMount is a mounting system based on specially developed adaptor rings, allowing the installation of COMPOSE FlexMount speakers in an almost infinite number of vehicles. Thus, the universal loudspeaker effortlessly becomes a vehicle-specific loudspeaker, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount adaptor ring. \u003cbr\u003eFor even greater installation flexibility, the Ci5 M80FM-D3 CTR scope of delivery also includes the \u003ca title=\"CFMK80-100\" href=\"https:\/\/www.audiotec-fischer.de\/en\/helix\/speakers\/compose\/flexmounts\/cfmk80-100\"\u003eCFMK80-100 adaptor ring\u003c\/a\u003e.
