The top is a unique hand-finished wood element that creates the connection with their loudspeaker siblings and is available in the three unmistakable Sonus faber finishes: the elegant Wengè, the iconic Red, and the essential Piano Black.\u003cbr\u003e\u003cbr\u003e\n\nSpeaker unit:\u003cbr\u003e\n The Gravis V \u0026amp; VI subwoofer speaker unit has a powerful, long stroke 12” design. The core technology is built on an extremely stiff and lightweight Trilaminated sandwich ‘ParaNanoCarbon’ cone diaphragm that resists flexing even with under strongest signal to produce the tightest and most accurate bass reproduction. A dual voice coil winding (each winding presents 4-ohm impedance) is also implemented to perfectly manage the driver’s excursion.\u003cbr\u003e\u003cbr\u003e\n\n Amplifier:\u003cbr\u003e\n For the Gravis V \u0026amp; VI subwoofers Sonus faber designed an extremely powerful and highly efficient Class AB amplifier rated at 850W into an 8 ohm load for the Gravis V and 1800W into 4 ohm for the Gravis VI. This huge energy reserve is responsible for a fast response and a wide frequency range. The latter is further linearized thanks to a specially designed DSP (Digital Signal Processor) implemented in the input preamp stage. This also allows numerous adjustments in order to optimize dynamic impact and sonic reproduction depth, satisfying every application need.\u003cbr\u003e\u003cbr\u003e\n\n Subwoofer connection and control:\u003cbr\u003e\n Many input options are available at the subwoofer backplate. Both high-level and low-level signals are accepted. The first by means of a Speakon© 4 pin connector, managing the two L and R channels. One or two-line level signals can be carried by means of balanced or unbalanced cables, respectively through two 3-pin XLR and RCA plugs. The LFE signal can be fed to the subwoofer through the shared XLR or RCA. If it becomes necessary to avoid cables back to the receiver\/preamp\/processor, Gravis V and VI integrate a wireless receiver for use with the optional transmitter, allowing complete connectivity without long wiring runs.\u003cbr\u003e\u003cbr\u003e\n\n The Gravis V and VI are fully controllable by means of a dedicated, user-friendly app. The user can choose among 4 presets, or even modify the cutoff frequency and the acoustical output phase for seamless integration with the main loudspeakers. Delay, parametric filters and limiters are also available for the most accurate sonic performance calibration.\u003cbr\u003e\u003cbr\u003e\n\n Last but not least, to minimize the energy footprint, the Gravis V and VI have a selectable auto--on and auto-off function.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications of Gravis VI:-\u003cbr\u003e\n\nLoudspeaker Type: Closed box loading, two-driver, active subwoofer\u003cbr\u003e\n Woofer: 2 x 320mm (12”) double coil 4+4ohm, very long throw, sandwich honeycomb cone, wide rubber surround woofer\u003cbr\u003e\n Amplifier Type: High performance, class AB amplifier\u003cbr\u003e\n Power amplifier: 1.800 W\u003cbr\u003e\n Frequency response: 18 Hz (@ - 6dB, acoustic Linkwitz 4th order roll-on, EQ1 setting) to Fc (user continuously adjustable)\u003cbr\u003e\n Mains input voltage: Selectable, 120Vac - 60Hz or 230 Vac - 50 Hz\u003cbr\u003e\n Fuse: T12A H 250V (for 230 Vac – 60Hz) T6.3A H 250V (for 110 Vac – 50Hz)\u003cbr\u003e\n Controls: Direct access Master volume; App control featuring: volume, continuously adjustable crossover frequency (40 to 150Hz), filtering slope 24dB\/oct; continuously adjustable signal phase; parametric EQ (4 presets available), Delay (1 to 20 ms); auto eq; auto power on\/off switch\u003cbr\u003e\n Additional features: Wireless connection (receiver included and transmitter unit available separately)\u003cbr\u003e\n Audio signal inputs: 2x Line level, left and right\/LFE RCA phono plugs (unbalanced) 2x Line Level, left and right\/LFE XLR plugs (balanced)\n 1x High level, Neutrik 4-pole Speakon©\u003cbr\u003e\nData connection: Ethernet (external control) and USB (for firmware update only)\u003cbr\u003e\n Power consumption: 0.5 W (Stand-by) 1800 W (Peak)\u003cbr\u003e\n Finish: Black leather\u003cbr\u003e\n Top finish: Piano Black, Wengè, Red\u003cbr\u003e\n Dimensions (H x W x D): 616 x 448.5 x 585.5 mm 24.2 x 17.6 x 23 in\u003cbr\u003e\n Weight: 52 Kg 114.6 lb\u003cbr\u003e\n Supplied accessories: \u003cbr\u003e\n User manual\u003cbr\u003e\n AC Power cord\u003cbr\u003e\n Neutrik Speakon© 10m amplifier to sub interconnection cable","brand":"Sonus Faber","offers":[{"title":"Sonus Faber Gravis VI - Piano Black","offer_id":57414278873420,"sku":"SFABERGRAVIS6-PB","price":5791.67,"currency_code":"GBP","in_stock":true},{"title":"Sonus Faber Gravis VI - Red","offer_id":57423505326412,"sku":"SFABERGRAVOS6-RED","price":5791.67,"currency_code":"GBP","in_stock":true},{"title":"Sonus Faber Gravis VI - Wenge","offer_id":57423505359180,"sku":"SFABERGRAVIS6-WENGE","price":5791.67,"currency_code":"GBP","in_stock":true},{"title":"Sonus Faber Gravis VI - Graphite","offer_id":57539497034060,"sku":null,"price":5791.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/gravis-vi-wenge.webp?v=1778752620","url":"https:\/\/www.stoneaudio.co.uk\/products\/sonus-faber-gravis-vi-subwoofer","provider":"Stone Audio","version":"1.0","type":"link"}
