{"product_id":"presonus-air18s-active-18-inch-subwoofer","title":"PreSonus AIR18S Active 18-Inch Subwoofer","description":"\u003cp\u003eEqually at home in mobile and installed systems, PreSonus AIR18s active subwoofers feature a 18-inch LF driver, driven by 1,200W of Class D power for a powerful, clear, and accurate low-end punch down to 35 Hz. DSP presets enable extended low-end performance and let you create ground-stacked or endfire subwoofer arrays. A variable alignment delay properly aligns your three-way system. Use the lowpass filter to set a crossover frequency for a smooth transition from sub-bass to full-range, adjust the master output level of the power amplifier, even turn the grille LED off for install applications or set it to illuminate only when the protection limiter is engaged—all at the touch of a button. AIR18s subwoofers also include integrated ground-stacking provisions and a castor kit.\u003c\/p\u003e \r\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \r\n\u003cul\u003e \r\n  \u003cli\u003e18-inch custom woofer with 3-inch voice coil\u003c\/li\u003e \r\n  \u003cli\u003e1,200W Class D power (dynamic)\u003c\/li\u003e \r\n  \u003cli\u003e35 Hz to 150 Hz frequency response\u003c\/li\u003e \r\n  \u003cli\u003e137 dB SPL (max)\u003c\/li\u003e \r\n  \u003cli\u003eStereo 1\/8” input\u003c\/li\u003e \r\n  \u003cli\u003eLocate controls adjust performance for arrayed and non-arrayed applications:\u003cbr\u003e \r\n    o Normal – non-arrayed applications\u003cbr\u003e \r\n    o Cardioid—create a ground-stacked cardioid subwoofer array (using two of the same model subwoofer)\u003cbr\u003e \r\n    o Endfire – create an endfire cardioid subwoofer array (using two of the same model subwoofer)\u003c\/li\u003e \r\n  \u003cli\u003eVariable lowpass filter lets you dial in upper frequency limit\u003c\/li\u003e \r\n  \u003cli\u003e“Mo’ Bass” tuning for extended low-end performance\u003c\/li\u003e \r\n  \u003cli\u003eAlignment delay up to 12m\u003c\/li\u003e \r\n  \u003cli\u003ePolarity invert\u003c\/li\u003e \r\n  \u003cli\u003eDefeatable front-panel LED for low-visibility installs\u003c\/li\u003e \r\n  \u003cli\u003eRugged, texture-painted birch enclosures and tour-grade 17 gauge steel grille\u003c\/li\u003e \r\n  \u003cli\u003eComfortable ergonomic handles, ground-stacking provisions, and castor provisions (castor kit included)\u003c\/li\u003e \r\n\u003c\/ul\u003e","brand":"Presonus","offers":[{"title":"Default Title","offer_id":48413411796,"sku":"1029603","price":999.95,"currency_code":"INR","in_stock":true}],"url":"https:\/\/sg-2111.myshopify.com\/products\/presonus-air18s-active-18-inch-subwoofer","provider":"SG_2111","version":"1.0","type":"link"}
