{"product_id":"sxp218-2x18-direct-radiating-dual-powered-subwoofer-4000w-black","title":"Martin Audio SXP218 2x18\" Direct Radiating Dual Powered Subwoofer 4000W Black","description":"The SXP218 achieves the ultimate in subwoofer performance for the most demanding professional applications – delivering very high output levels and superb transient performance with minimal distortion. With an operating range of 35Hz-150Hz ± 3dB, it houses dual 18” long-excursion (460mm)\/4” (100mm) voice coil drivers with water-resistant cones and triple roll surrounds. The design of the 18” drivers maximises output while minimising power compression and distortion, and the eight reflex ports have a large frontal area to reduce turbulent air noise at very high levels. With a prodigious maximum SPL capability of 143dB peak at 1 metre, the SXP218 is the ideal subwoofer for touring sound reinforcement, theatre and portable live sound applications — as well as premium installations — that require low frequency augmentation with low distortion at very high output levels.A self-powered system, the SXP218 incorporates a Class D amplifier, DSP and Dante™ digital audio networking — simplifying set-up, enhancing control and eliminating amplifier racks. The onboard amplifier delivers a total of 4000W peak output to the drivers, and its switched-mode power supply auto-ranges to global mains voltages from 100 to 240V 50\/60Hz. DSP functions — including parametric EQ, delay, muting, gain and preset selection — can be controlled over Ethernet from a PC or Windows® tablet via intuitive VU-NET™ proprietary software.For simple set-ups, ‘plug-and-play’ presets for operation with the CDD-LIVE 8, CDD-LIVE 12 or CDD-LIVE 15 — as well as a user-defined preset — can be selected on the rear panel, instead of using computer control. Additional presets provide the appropriate settings for the rear-facing subwoofer in a cardioid pair.Product Features\nDual-driver, self-powered subwoofer\n2 x 18” (460mm) drivers with 4” (100mm) voice coils\nVery high output capability\nOnboard Class D amplification and DSP\nDante™ Digital Audio networking\nGlobal mains operation with Power Factor Correction\nTour-grade plywood enclosure with flying inserts\nIP24 rating option with rain cowl\nApplications\nLive sound reinforcement\nTheatre sound\nCorporate AV events\nFixed installations in concert halls, ballrooms and HoW\nBars and clubs\nOutdoor restaurant, bar and hotel entertainment areas\nConcourses and Theme Parks\nProduct SpecificationsACOUSTICSTYPE:  Dual-driver, direct radiating powered subwooferFREQUENCY\nRESPONSE:  35Hz – 150Hz ±3dB, -10dB @ 30Hz\nDRIVER:  2x 18” (460mm)\/4” (100mm) voice coil, long excursion, ferrite magnet, waterproof cone\nINPUT SENSITIVITY:  -30dBu for 100dB SPL\nMAXIMUM SPL:  140dB continuous \/ 143dB peak\nDISPERSION:  Omnidirectional \/ or Cardioid (paired)\nCROSSOVER:  Active Presets for CDD Live 8, 12 \u0026amp; 15 mono-pole or cardioid (paired)\nMODULE AUDIO INPUT\nCONNECTORS:  Female XLR input, male XLR link output, Dante Audio Neutrik® Ethercon\nANALOGUE INPUT IMPEDANCE:  20 kΩ balanced to ground\nMAXIMUM ANALOGUE INPUT LEVEL:  24.6 Vpp (+21dBu), over voltage protected\nINTERNAL PROCESSING:  Multi-channel DSP, programmable via TCP\/IP using VU-Net software\nPEQ\/shelving filters\nUp to 48dB\/Oct LPF\nUp to 200mS input delay\nPre-set selection via rear panel switch\n\n\nNETWORK\nCONNECTORS:  2 x Neutrik® Ethercon RJ45\nPROTOCOL:  TCP\/IP and UDP\/IP\nAMPLIFIER MODULE\nTYPE:  Two 2 channel switch-mode, class D, Bridged Tied Load\nPEAK OUTPUT POWER:  4000W\nAVERAGE EFFICIENCY:  89%\nCOOLING:  External fan\nMAXIMUM AMBIENT TEMPERATURE:  40°C (104°F) for full output\nPOWER SUPPLY\nTYPE:  Switch mode, fixed frequency with PFC\nAC INPUT OPERATING RANGE:  85 – 265V ~ AC, 50 - 60Hz\nPOWER FACTOR:  \u0026gt; 0.98\nNOMINAL POWER CONSUMPTION:  250W\nMAINS CONNECTOR:  Neutrik® Powercon True1\nMECHANICAL\nENCLOSURE:  Extensively braced multi-laminate birch plywood.\nFINISH:  Durable Polyurea Coating\nPROTECTIVE GRILLE:  Black perforated Zintec\nFITTINGS:  \nTwo skids on base, with mating channels on top\n16 x M8 inserts for optional castors\n24 x M10 mounting points\n4x Bar handles, 2 on each side\n4x fittings for optional transit cover\nM20 Pole mount insert\n\n\nIP RATING:  IP24 factory option available\nDIMENSIONS:\n(W) 1085mm x (H) 537mm x (D) 792mm (920mm including castors)\n(W) 42.72in x (H) 21.13in x (D) 31.16in (36.20in including castors)\n\n\nWEIGHT:  101.5kg (224lbs) w\/o castors 105kg (231lbs) with castors\n","brand":"Martin Audio","offers":[{"title":"Default Title","offer_id":58332913467766,"sku":"MAUSXP218","price":6314.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0361\/2681\/files\/MAUSXP218_Martin_Audio_SXP218_Image_1.jpg?v=1784913258","url":"https:\/\/spartanmusic.co.uk\/products\/sxp218-2x18-direct-radiating-dual-powered-subwoofer-4000w-black","provider":"Spartan Music","version":"1.0","type":"link"}
