8-720 HEX


The 8-720 2x2 Ohm double voice coil woofer has been developed especially for smaller enclosures with a volume of only 4,5 ltr. The woofer performs precisely and with a high dynamic. the extremely stiff hexacone diaphragm grants a precise bass reproduction. The relatively small mounting dimension allows an all purpose application. An ideal complement to all 2-way systems
