HELIX Ci7 C165.2FM-S3

• 6,5″ 2 way coaxial• 225W• 3 Ohm• FlexMount compatible&lt p&gt Born 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 HELIX COMPOSE platform that, according to the motto ″developed inside the vehicle, for the vehicle″, combines classic universal speakers with the advantages of vehicle-specific systems.&lt br&gt &lt br&gt 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.&lt br&gt &lt br&gt i7 – High-end Car Hifi made in Germany&lt br&gt Our HELIX COMPOSE i7 series represents uncompromising high-end for an outstanding sound experience in the automobile. With obvious influence of the high-end sister brand BRAX, the i7 speaker series is completely made in Germany and optimized for uncompromising music enjoyment. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time. In addition, HELIX COMPOSE introduces four new mechanical technologies that offer unbeatable practical benefits.&lt br&gt &lt br&gt High efficiency&lt br&gt HELIX COMPOSE equals smart engineering and accordingly implements highly efficient 3 Ohms technology, that perfectly harmonizes with all HELIX and MATCH amplifiers and at the same time allows a clearly perceptible plus in efficiency and maximum sound pressure.&lt br&gt &lt br&gt High-End Coaxial Coincident Speaker&lt br&gt The Ci7 C165.2FM-S3 is a unique coaxial speaker that combines the best of the Ci7 W165FM-S3 High-End midbass driver and the Ci7 T20FM-SC high-end tweeter. Due to its complex design, the Ci7 C165.2FM-S3 is not just a simple coaxial speaker but a true coincident driver. This provides the advantage that the sound from both drivers is produced at exactly the same time, turning the speaker into a point-source. This results in extremely precise and time-coherent sound reproduction, which is particularly advantageous in acoustically challenging environments, making this speaker another smart, practical solution in the COMPOSE platform.&lt br&gt With the i7’s renowned UHD paper cone and the silk-dome tweeter, incl. the integrated coupling volume damped with pure lamb’s wool, the C165.2FM-S3 delivers an exceptional combination of powerful, precise midbass and brilliant, smooth treble response. The alignment of the drivers along the same sound axis ensures optimal phase coherence and a consistent sound image. This makes the C165.2FM-S3 a versatile solution for audiophiles who want to experience a coherent soundstage from a single speaker position, while still benefiting from the intelligence and integration-friendly design of the COMPOSE platform.&lt br&gt &lt br&gt High-tech polymer basket&lt br&gt All HELIX COMPOSE i7 and i3 speaker baskets are 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.&lt br&gt &lt br&gt FlexMount165 – Universal meets car-specific&lt br&gt FlexMount 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.&lt br&gt &lt br&gt ProConnect – The new industry standard&lt br&gt Our innovative ProConnect terminal of the midbass is the new industry standard: A professional, automotive connector that provides a safe connection to our WireKits, but also allows the use of conventional speaker cables or car-specific adaptor cables via flat plugs, giving maximum flexibility in the design of the sound system upgrade. Furthermore, the connection is interlocked, offers reverse polarity protection and is electrically and mechanically highly stressable.&lt br&gt &lt br&gt WireKits – Plug &amp amp Play at its best&lt br&gt Our WireKits realize the connection of HELIX COMPOSE coaxial speaker system to the original wiring harness in the most comfortable way. With manufacturing according to the high standards of the automotive industry, these arrestable adaptor cables meet all requirements for the harsh environmental conditions that installers are facing in vehicles every day.&lt br&gt &lt br&gt &lt br&gt Features&lt br&gt 2-way high-end coaxial coincident speaker which combines outstanding sound performance with versatile physical integration options&lt br&gt Concentric speaker as a true point source for superior sound dispersion &amp amp unparalleled audio precision&lt br&gt Tweeter&lt br&gt Super-wide dispersion 0.75” / 20 mm high-end silk dome tweeter with coupling volume for lowest possible resonance frequency&lt br&gt Exceptionally lightweight and fine-meshed silk dome ensures brilliant and smooth treble response&lt br&gt Integrated, dampened coupling volume allows a low crossover frequency thanks to its low resonance frequency&lt br&gt 4 Ohms impedance&lt br&gt Midbass&lt br&gt 6.5″ / 165 mm midbass with Ultra High Damping (UHD) crafted paper cone for outstanding impulse response and unmatched frequency response&lt br&gt High-tech polymer composite basket reinforced with glass beads for enormous rigidity and minimized ringing&lt br&gt Large 1.46” / 37 mm voice coil ensures minimum thermal compression and high power handling&lt br&gt High efficiency and 3 Ohms technology for maximized power output of the amplifier&lt br&gt Automotive grade ProConnect connection terminal allows the use of conventional speaker cables or a fast, secure and fail-safe connection via optionally available WireKits&lt br&gt Designed for the optionally available car-specific FlexMount165 adaptors which allow an acoustically optimized and professional integration in the original mounting location of the vehicle&lt br&gt Designed for optionally available, car-specific WireKits which allow a non-destructive integration&lt br&gt Made in Germany&lt br&gt Note: The speaker does not have an integrated crossover. For active operation, two amplified DSP channels per speaker are required and it is essential to set a highpass filter for the tweeter in the pre-connected DSP or DSP amplifier. Alternatively, the separately available crossover Ci7 FX-UNI.2 can be used.&lt /p&gt
