{"product_id":"qsc-sb-218f","title":"QSC SB-218F","description":"\u003cp class=\"bodytext\"\u003eThe SB-118F single 18-inch and SB-218F dual 18-inch subwoofers are designed specifically for low frequency enhancement in cinema applications, especially for low frequency content of the surround channels using bass management techniques. A common application is suspending these enclosures from the cinema ceiling in proximity to the wall mounted surround loudspeakers for which the SB-118F\/218F provides low frequency enhancement. The SB-118F\/218F covers the frequency range from 37 Hz to 230 Hz.\u003c\/p\u003e\n\u003cp class=\"bodytext\"\u003eThese enclosures are designed for safe and easy suspension using eight built-in M10 fly points. Heavily braced, tour grade 15 mm plywood construction provides great strength while keeping weight to a minimum. The custom 800 watt, 18-inch transducers were developed especially for cinema use. They feature large 4-inch (101 mm) voice coils and a multi-vented pole piece to ensure cool operation, even at high power levels. Cooler temperatures increase transducer lifespan and decrease the problem of power compression at high power.\u003c\/p\u003e","brand":"DEV ELECTRONICS","offers":[{"title":"Default Title","offer_id":43771332296940,"sku":"","price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0650\/4159\/6652\/files\/Untitleddesign_17_0970f4f8-2f56-4d40-9a47-7977a6bfb612.jpg?v=1683623048","url":"https:\/\/www.develectronics.com\/products\/qsc-sb-218f","provider":"DEV ELECTRONICS","version":"1.0","type":"link"}
