{"product_id":"infinity-kappa-9-2i","title":"Infinity Kappa 9.2i","description":"\u003cp\u003eTwo newly developed 30 cm cone-type woofers using IMG cones are mounted in the low range. The IMG cone is a lightweight, highly rigid diaphragm that retains the characteristics of polypropylene. It is made from a composite material of graphite fiber and polypropylene using high-temperature, high-pressure injection molding. In this cone, the graphite fibers are arranged radially from the center to the outer circumference, resulting in a large non-deformation operating range and excellent performance without cone breakup. The combination of polypropylene and graphite fiber also ensures excellent damping and high strength without unnecessary resonance. In addition, the Kirby linear cone features a specially designed shape that adds strength to the piston during motion, while the newly designed inverted dust cap further improves strength, enabling motion with minimal cone deformation even under high-power conditions. The second-generation Kappa series is a further improvement of the IMG cone, achieving a weight reduction of approximately 10% and a hardness improvement of approximately 5%. It also uses a lightweight, heat-resistant Kapton bobbin and ribbon wire for high currents.  A 16 cm cone-type mid-bass unit is installed in the mid and low ranges. An IMG cone is also used in this unit.  A newly designed 7.6 cm dome-type mid-high unit is installed in the mid and high ranges. This unit is an improvement on the polydome used in the original Kappa series and uses a newly developed ultrathin (0.3 mm) soft polypropylene composite diaphragm. This low-Q dome-shaped diaphragm is driven from the dome periphery by a large-diameter edge-wound voice coil. In addition, an aluminum mesh diffuser has been added to the back of the dome. This diffuser suppresses disturbances in the frequency response caused by back waves without placing a load on the dome-shaped diaphragm, resulting in a flatter frequency response and lower distortion. Furthermore, the acoustic energy radiated to the back surface of the dome is guided from the center of the magnetic circuit through a special structure to the rear cavity, eliminating the influence of back sound pressure.  EMIT-R, Infiniti's original planar tweeter, is installed in the high range. The EMIT-R uses an ultrathin Kapton membrane as the flat diaphragm, with a ring-shaped voice coil photo-etched onto the surface. By combining this diaphragm with a specially shaped magnetic circuit, the diaphragm is driven directly. This achieves a flat response with few peaks and valleys, wide-directional characteristics, and a low distortion factor.  The crossover section incorporates an L\/C tuning circuit that draws sufficient current from the power amplifier to the woofer to extend the bass playback range. This circuit can be turned off and can be combined with amplifiers that are relatively weak against low-impedance loads.  Equipped with level controls for the mid and high ranges.  The enclosure uses a column-shaped polygonal design to minimize the effects of internal standing waves and uses high-density, low-resonance particleboard for a natural sound.  Bi-wiring is supported.\u003c\/p\u003e\n\n\u003cp\u003eMethod 4-Way, 5-Speaker, Bass Reflex System, Floor-Standing Units Used For low range: 30 cm cone x2 For mid and low range: 16 cm cone-type For mid and high ranges: 7.6 cm dome-type For high frequencies: planar-type (EMIT-R) Frequency response 27 Hz to 35 kHz +\/- 2 dB Input impedance 4 ohms Output sound pressure level 89 dB Allowable input 400 W Crossover frequencies 180 Hz, 750 Hz, 3.5 kHz External dimensions Width 457 x Height 1,525 x Depth 376 mm Weight 54 kg Attachment Spikes\u003c\/p\u003e","brand":"Infinity","offers":[{"title":"Default Title","offer_id":59370778263897,"sku":"2679","price":1390.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/5721\/8905\/files\/infinity-kappa-9.2i-1.jpg?v=1789119416","url":"https:\/\/wenwaudio.com\/en-de\/products\/infinity-kappa-9-2i","provider":"W\u0026WAudio","version":"1.0","type":"link"}
