Utilizing a neodymium driver in a reflex-loaded design, it achieves a remarkable frequency range down to 20Hz with a peak output of 142dB.\r\n\r\nDesigned with cardioid deployment in mind, the MS121 offers advanced arraying options including electronic delay steering for optimized rear rejection. The subwoofer features a 4-point rigging system for suspension—either standalone or in combination with MV210-HC line arrays—supporting up to 9 units at a 10:1 safety factor.\r\n\r\nThe rugged enclosure is crafted from Baltic birch plywood with a tour-grade finish, ensuring reliability in demanding conditions. For ground stack setups, integrated feet and stacking recesses provide added stability, while the M20 pole mount allows use with satellite speakers. NL4 connectors on both the rear and front panels simplify signal routing for standard or cardioid applications.\r\n\r\n\u003ch3\u003eModel Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e21\" neodymium driver in a reflex-loaded enclosure\u003c\/li\u003e \u003cli\u003e2000W continuous, 8000W peak power handling\u003c\/li\u003e \u003cli\u003eUp to 142dB maximum SPL\u003c\/li\u003e \u003cli\u003eCardioid-arrayable with front and rear connectors\u003c\/li\u003e \u003cli\u003eOptimized for use with Lab Gruppen amps and Lake DSP\u003c\/li\u003e \u003cli\u003e4-point flyable rigging system supports mixed arrays\u003c\/li\u003e \u003cli\u003eGround stacking feet with stacking recesses\u003c\/li\u003e \u003cli\u003eM20 threaded pole mount for satellite configurations\u003c\/li\u003e \u003cli\u003eWeather-resistant IP54-rated enclosure\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eModel Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eFrequency Response (-3 dB): 25 Hz – 95 Hz\u003c\/li\u003e \u003cli\u003eFrequency Response (-10 dB): 20 Hz – 200 Hz\u003c\/li\u003e \u003cli\u003eMax SPL: 142 dB\u003c\/li\u003e \u003cli\u003ePower Handling: 2000W continuous \/ 8000W peak\u003c\/li\u003e \u003cli\u003eSensitivity: 97 dB (1W @ 1m)\u003c\/li\u003e \u003cli\u003eNominal Impedance: 8 Ω\u003c\/li\u003e \u003cli\u003eDispersion: Omnidirectional (configurable cardioid)\u003c\/li\u003e \u003cli\u003eDriver: 1 x 21\" (530 mm) neodymium LF\u003c\/li\u003e \u003cli\u003eConnectors: 3 x twist-lock NLT4MP STX (rear + front)\u003c\/li\u003e \u003cli\u003eWiring: Pins 1+\/1- LF, Pins 2+\/2- LINK (Front: Pins 2+\/2- only)\u003c\/li\u003e \u003cli\u003eDimensions: 23.6 x 30.6 x 31.5 in (599 x 777 x 800 mm)\u003c\/li\u003e \u003cli\u003eWeight: 192.7 lb (87.4 kg)\u003c\/li\u003e \u003cli\u003eEnclosure: 21 mm and 18 mm marine birch plywood\u003c\/li\u003e \u003cli\u003eFinish: Polyurethane black\u003c\/li\u003e \u003cli\u003eGrille: Powder-coated perforated steel\u003c\/li\u003e \u003cli\u003eIP Rating: IP54\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eWhat's In The Box\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eTS-MS121 subwoofer\u003c\/li\u003e \u003cli\u003eUser documentation\u003c\/li\u003e \u003c\/ul\u003e","brand":"TurboSound","offers":[{"title":"Default Title","offer_id":51589785518362,"sku":"116608","price":5400.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/2714\/9082\/files\/turbosound-ts-ms121--21in-subwoofer---142db-spl--touring-and-install-with-cardioid-capability_b46b6481-cc69-418c-b7d4-ac45bca2e7de.webp?v=1768599119","url":"https:\/\/squarecable.com\/products\/turbosound-ts-ms121-21in-subwoofer-142db-spl-touring-and-install-with-cardioid-capability","provider":"SquareCable","version":"1.0","type":"link"}
