{"product_id":"sundown-audio-sld-12-flachsubwoofer","title":"SLD-12","description":"\u003cp\u003eThe Sundown Audio SLD series, which includes the SLD-12 12-inch shallow subwoofer, can be considered a \"reboot\" of the SD-2 line from 2011. The SD-2 was essentially a \"shallow SA v1\"—that is, it had the same cone, surround, and spider as the SA, but a shorter motor with a shorter coil. Starting with the 3rd generation (SD-3), the SD series took a different direction—more towards SQ and sealed enclosures (this also applies to the SD-4 series). Due to high demand, we launched the SLD series to bring back a highly abuse-tolerant \"shallow\" series that works well with open enclosures!\u003c\/p\u003e\n\u003cp\u003eSimilar to the current SD-4 series, we have used solid pole pieces, so the SLD can also be mounted directly on the rear enclosure wall to reduce the required net depth. Compared to the old SD-2, we have introduced numerous important upgrades: pole piece channels for reduced air noise and improved cooling, top plate \"slots\" for better cooling and less distortion, as well as a magnet ID shorting ring. Regarding long-term reliability, we have also screwed the tooth ring, assembled the motor with screws, screwed on the aluminum pole cap, and added \"Mini-XL\" lead wires to ensure flawless operation for many years.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eXmax = 12 mm in one direction at 70% BL\u003c\/li\u003e\n\u003cli\u003eXmech is a hard limit of 25 mm in one direction (more than double Xmax is a very generous limit)\u003c\/li\u003e\n\u003cli\u003eRMS power = 600 watts\u003c\/li\u003e\n\u003cli\u003e2.5-inch black aluminum voice coil former for excellent heat dissipation\u003c\/li\u003e\n\u003cli\u003eHigh-temperature 4-layer copper voice coil wire\u003c\/li\u003e\n\u003cli\u003eSewn-on \"Mini-XL\" lamellar cables to prevent fatigue and failure\u003c\/li\u003e\n\u003cli\u003eSolid poles with high-speed ventilation channels milled around the OD\u003c\/li\u003e\n\u003cli\u003eVentilated, EMD-cut top plate design\u003c\/li\u003e\n\u003cli\u003eScrewed motor construction for maximum durability and resistance to mechanical failures\u003c\/li\u003e\n\u003cli\u003eThis motor is screwed from the top, so the screws are not visible from the back like on some other models.\u003c\/li\u003e\n\u003cli\u003eMagnet ID shorting ring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eT\/S SPECS SLD 12\" D2\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003eRE (Ohm) 3.65\u003c\/li\u003e\n\u003cli\u003eFS (Hz) 42.959\u003c\/li\u003e\n\u003cli\u003eVAS (L) 26.889\u003c\/li\u003e\n\u003cli\u003eQes 0.691\u003c\/li\u003e\n\u003cli\u003eQms 2.227\u003c\/li\u003e\n\u003cli\u003eQts 0.415\u003c\/li\u003e\n\u003cli\u003eLe (mH)\u003c\/li\u003e\n\u003cli\u003eBL (NA) 19.868\u003c\/li\u003e\n\u003cli\u003eMms (grams) 204.319\u003c\/li\u003e\n\u003cli\u003eCms (uM\/N) 67.177\u003c\/li\u003e\n\u003cli\u003eSensitivity (dB @ 1w\/1m) 88.1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eT\/S SPECS SLD 12\" D4\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003eRE (Ohm) 6.85\u003c\/li\u003e\n\u003cli\u003eFS (Hz) 45.142\u003c\/li\u003e\n\u003cli\u003eVAS (L) 29.481\u003c\/li\u003e\n\u003cli\u003eQes 0.619\u003c\/li\u003e\n\u003cli\u003eQms 2.298\u003c\/li\u003e\n\u003cli\u003eQts 0.487\u003c\/li\u003e\n\u003cli\u003eLe (mH)\u003c\/li\u003e\n\u003cli\u003eBL (NA) 23.025\u003c\/li\u003e\n\u003cli\u003eMms (grams) 168.773\u003c\/li\u003e\n\u003cli\u003eCms (uM\/N) 73.652\u003c\/li\u003e\n\u003cli\u003eSensitivity (dB @ 1w\/1m) 88.3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eSealed enclosure 28 liters\u003c\/li\u003e\n\u003cli\u003ePorted enclosure 42 liters\u003c\/li\u003e\n\u003cli\u003eRecommended tuning 35Hz\u003c\/li\u003e\n\u003cli\u003eRecommended port area 170cm²\u003c\/li\u003e\n\u003cli\u003eDepth 13.8cm\u003c\/li\u003e\n\u003cli\u003eOuter diameter 31.9cm\u003c\/li\u003e\n\u003cli\u003eCutout 28.2cm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sundown Audio","offers":[{"title":"D2 (2x2 Ohm)","offer_id":44395315429643,"sku":"SLD-12-D2","price":429.0,"currency_code":"EUR","in_stock":true},{"title":"D4 (2x4 Ohm)","offer_id":44395315462411,"sku":"SLD-12-D4","price":429.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0271\/9478\/5927\/files\/sundown-audio-sld-12-12-30cm-flachsubwoofer-masori-kaufen.jpg?v=1781828113","url":"https:\/\/masprori.com\/en\/products\/sundown-audio-sld-12-12-inch-flat-subwoofer","provider":"Masori | Shop","version":"1.0","type":"link"}
