The Tecnare SW218V is a very powerful double 2 x 18-inch hybrib subwoofer cabinet. It has been designed for medium to long throw sound reinforcements. The response given with this subwoofer is very deep, starting at 38 Hz. It delivers a tight punch combined with a low deep response. The acoustic loading of the Speakers, perfectly matched, prevents cones to over run maximum cone displacement. It is the perfect solution for all kind of touring systems. Castors can be supplied as an accessory.
