Power	Diameter	Impedence
600 watts	15" - 38.1 cms	ohms

	Heavy duty 15" cast aluminium frame with extra wide flange for increased rigidity.

	600WRMS

	4” copper voice coil assembly

	125 oz. ceramic magnet

	B/L in excess of 27 T/m for fast accurate lows

	Double suspension system maintaining a pure piston action for the moving mass even when driven with the most complex programme input signals and provides additional durability against the rigours of life on the road

Description:

Perfectly suited for 1x15" or 2x15" horn loaded sub bass designs, the smooth mid range makes it easy to integrate with the PD.C2 or PD.C14 compression drivers. This transducer delivers commanding and powerful lows in compact cabinet designs.
