It extends the system’s low-frequency response down to 38Hz and delivers exceptional impact, with a peak SPL of 130dB (136dB with crest factor 4).\u003cbr\u003e\nQ118 features an 18” (460 mm) driver with a 4” (100 mm) voice coil, housed in a durable plywood enclosure finished in tough black paint. A perforated, impact-resistant steel grille protects the driver, while slot ports enhance efficiency and minimize noise turbulence.\u003cbr\u003e\nDesigned for versatile deployment, Q118 can be used individually, stacked or flown using integral M10 inserts. It also includes an M20 1.4” (35 mm) pole-mount fitting for seamless integration with other loudspeakers in BlacklineQ series. There are two signal link outputs—one positioned at the top and one at the bottom of the enclosure when oriented vertically. This allows for flexible, discreet and tidy signal connections to other BlacklineQ loudspeakers, regardless of setup.\u003cbr\u003e\nErgonomic side handles ensure easy handling and rubber feet on the base align with top-surface recesses to provide secure and stable stacking. A castor kit is available as an optional accessory.\u003cbr\u003e\nWhen paired with BlacklineQ Series full-range systems, crossover and EQ functions can be managed via the DX0.4, DX0.6 or DX4.0 system controllers, or the onboard DSP of an iKON amplifier.\u003cbr\u003e\nProduct Features\u003c\/p\u003e\n\n\u003cp\u003eCompact, direct-radiator subwoofer\u003cbr\u003e\n1 x 18” (460mm) driver with 4” (102mm) voice coil\u003cbr\u003e\nPeak SPL of 130dB (136dB with crest factor 4)\u003cbr\u003e\nDurable plywood enclosure\u003cbr\u003e\nSlot ports for reduced air noise\u003cbr\u003e\nPerforated steel grille\u003cbr\u003e\nM20 \/ 1.4” (35mm) pole-mount socket\u003cbr\u003e\n8Ω nominal impedance\u003cbr\u003e\nIntegral ergonomic handles\u003cbr\u003e\nRebate recesses for stable vertical stacking\u003cbr\u003e\nM10 flying inserts\u003cbr\u003e\nFittings for optional castors\u003cbr\u003e\nThree NL4 connectors\u003cbr\u003e\n85% Post Consumer Recycled ABS Plastic\u003cbr\u003e\nFSC Certified Cardboard Packaging\u003cbr\u003e\nBiodegradable Box Sealing tape\u003c\/p\u003e\n\n\u003cp\u003eProduct Specifications\u003c\/p\u003e\n\n\u003cp\u003eType:  Compact, high-performance 18\" subwoofer\u003cbr\u003e\nFrequency Response:  38 Hz – 100 Hz ± 3 dB, -10 db @ 31 Hz\u003cbr\u003e\nDriver:  18” (460 mm) with 4” (100 mm) long excursion voice coil, ferrite motor system\u003c\/p\u003e\n\n\u003cp\u003eRated Power:  800 W AES, 3200 W peak\u003cbr\u003e\nRequired Electronics:  Processor and amplifier, or a combined amplifier-processor unit\u003cbr\u003e\nRecommended Electronics:  DX0.4, DX0.6 or DX4.0 system processor and VIA amplifier, or iKON amplifier-processor\u003cbr\u003e\nSensitivity:  95 dB\u003cbr\u003e\nMaximum SPL:  124 dB continuous, 130 dB peak, 136 dB peak with crest factor 4\u003cbr\u003e\nNominal Impedance:  8 ohm\u003cbr\u003e\nDispersion:  Omnidirectional\u003cbr\u003e\nCrossover:  N\/A\u003cbr\u003e\nEnclosure:  Durable plywood\u003cbr\u003e\nFinish:  Black textured paint\u003cbr\u003e\nProtective Grille:  Black perforated steel grille with scrim cloth backing\u003cbr\u003e\nConnectors:  3 x NL4 connectors: 2 at bottom rear (input and link A), 1 at top rear (link B)\u003cbr\u003e\nPin Connections (Input):  1+\/1–\u003cbr\u003e\nPin Connections (Link A):  1+\/1– to 1+\/1– and 2+\/2– to 2+\/2–\u003cbr\u003e\nPin Connections (Link B):  1+\/1– on input to 2+\/2– on link B\u003cbr\u003e\nFittings:\u003c\/p\u003e\n\n\u003cp\u003e16 x M10 inserts: 2 on top, 2 on bottom, 4 on left, 4 on right, 4 on rear\u003cbr\u003e\n16 x M8 inserts on rear for optional castors\u003cbr\u003e\n2 x bar handles with recycled ABS pockets: 1 on each side\u003cbr\u003e\nM20 top-mounted thread plate for pole mounting\u003cbr\u003e\n4 x skids on base, 4 x recesses on top: for stacking vertically\u003c\/p\u003e\n\n\n\u003cp\u003eDimensions (WxHxD):  530 mm x 606 mm x 690 mm (20.9 in x 23.9 in x 27.2 in)\u003cbr\u003e\nWeight:  45.5 kg (100.3 lbs)\u003cbr\u003e\nAccessories (Optional):\u003c\/p\u003e\n\n\u003cp\u003eM10 eye bolt HTKCT06\u003cbr\u003e\nWind-up telescopic pole ASF20071\u003cbr\u003e\nSet of four castors WHEELKIT\u003cbr\u003e\nTransit cover\u003c\/p\u003e","brand":"Martin Audio","offers":[{"title":"Default Title","offer_id":58332911141238,"sku":"MAUQ118","price":1064.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0361\/2681\/files\/WEBMAU00559_Q118B_1.jpg?v=1784913189","url":"https:\/\/spartanmusic.co.uk\/products\/blackline-q118-18-passive-subwoofer-with-4-voice-coil-black","provider":"Spartan Music","version":"1.0","type":"link"}
