The subwoofer features a 3600W Class-D amplifier module that powers two 12\", long-excursion drivers in a dual 6th order band-pass design that creates a cardioid polar pattern with -15 dB SPL front-to-rear attenuation. The unit offers a frequency response of 44 to 104 Hz (-6 dB) with a peak SPL of 132 dB (at 1m).\u003cbr\u003e\r\n\u003cbr\u003e\r\nTypically, subwoofers are omnidirectional, radiating in all directions. This results in a build-up of low frequencies on-stage and wasted LF energy at the rear of the system. Sound engineers found a way to create a cardioid (heart-shaped) polar pattern, which removes much of the low energy at the rear of the subwoofers. Unfortunately, this system required the use of subwoofer arrays with multiple enclosures, clever placement, and processing of delay and polarity to redirect the energy.\u003cbr\u003e\r\n\u003cbr\u003e\r\n\r\n\r\n\u003c\/p\u003e\u003cp\u003e \u003cem\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\r\n\u003cp\u003e• 3600 Watt Class D power module \u003cbr\u003e\r\n• Dual 12-inch long excursion drivers; Dual 6th order band-pass design \u003cbr\u003e\r\n• 15 dB SPL attenuation front-to-rear   \u003cbr\u003e\r\n• Two M20 threaded sockets (one on top, one on side) accept 35 mm speaker pole  \u003cbr\u003e\r\n• Four low-noise, heavy-duty casters \u003cbr\u003e \r\n\r\n\u003c\/p\u003e\r\n\r\n\r\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eWhat's In The Box?\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\r\n\u003cp\u003e• QSC KS212C Powered 3600W Dual 12\" Cardioid Subwoofer \u003cbr\u003e\r\n• Locking IEC Power Cord \u003cbr\u003e\r\n• 4 x Heavy-Duty Casters \u003cbr\u003e\u003c\/p\u003e","brand":"QSC","offers":[{"title":"Default Title","offer_id":52862842339439,"sku":"KS212C-SHOP","price":2299.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/5229\/5535\/files\/1828776.jpg?v=1774750459","url":"https:\/\/digitaldjgear.com\/products\/qsc-ks212c-3600w-active-cardioid-subwoofer","provider":"Digital DJ Gear","version":"1.0","type":"link"}
