Rear panel controls offer adjustable crossover (80Hz\/120Hz), polarity switch, and EQ settings for tuning to any system or space.\r\n\r\nWith a built-in stereo crossover, the SUB 702AS MK3 is easy to integrate into full-range systems. M20 pole mounting, recessed side handles, and a steel grille with dust-reducing foam lining make it ideal for portable setups and installs alike.\r\n\r\n\u003ch3\u003eModel Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e1400W Class-D amplifier (700W RMS)\u003c\/li\u003e \u003cli\u003e12\" woofer with 2.5\" voice coil and ceramic magnet\u003c\/li\u003e \u003cli\u003eMax SPL: 129 dB for tight and punchy low-end\u003c\/li\u003e \u003cli\u003eBass Motion Control (BMC) excursion management\u003c\/li\u003e \u003cli\u003e80Hz \/ 120Hz crossover switch with phase invert\u003c\/li\u003e \u003cli\u003eRear-panel EQ, volume, and polarity controls\u003c\/li\u003e \u003cli\u003eStereo XLR inputs and outputs\u003c\/li\u003e \u003cli\u003eFanless convection cooling for silent operation\u003c\/li\u003e \u003cli\u003eM20 threaded pole mount and rugged side handles\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eModel Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eMax SPL: 129 dB\u003c\/li\u003e \u003cli\u003ePower Output: 1400W Peak \/ 700W RMS\u003c\/li\u003e \u003cli\u003eFrequency Response: 40 Hz – 120 Hz\u003c\/li\u003e \u003cli\u003eWoofer: 12\" with 2.5\" voice coil\u003c\/li\u003e \u003cli\u003eInputs: XLR (balanced\/unbalanced)\u003c\/li\u003e \u003cli\u003eOutputs: XLR\u003c\/li\u003e \u003cli\u003eControls: Volume, EQ, Phase, Xover (80Hz\/120Hz)\u003c\/li\u003e \u003cli\u003eCooling: Convection (fanless)\u003c\/li\u003e \u003cli\u003eCabinet: Baltic birch plywood with polyurea coating\u003c\/li\u003e \u003cli\u003eMount: M20 threaded pole mount\u003c\/li\u003e \u003cli\u003eGrille: Steel with internal foam backing\u003c\/li\u003e \u003cli\u003eDimensions: 20.59 x 14.17 x 20.28 in (523 x 360 x 515 mm)\u003c\/li\u003e \u003cli\u003eWeight: 47.4 lb (21.5 kg)\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eWhat's In The Box\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eRCF SUB 702AS MK3 Subwoofer\u003c\/li\u003e \u003cli\u003eVDE Power Cable\u003c\/li\u003e \u003cli\u003eUser Guide\u003c\/li\u003e \u003c\/ul\u003e","brand":"RCF","offers":[{"title":"Default Title","offer_id":50153248620826,"sku":"114595","price":999.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/2714\/9082\/files\/rcf-sub-702-as-mk3--12in--129db.webp?v=1756141205","url":"https:\/\/squarecable.com\/products\/rcf-sub-702-as-mk3-12in-129db","provider":"SquareCable","version":"1.0","type":"link"}
