PR312WA02_03_Passive_Radiators

Navigate


			The two models PR312WA02 and PR312WA03 are identical except for cone colour. PR312WA02: Natural coloured alu cone, PR312WA03: Black alu cone. PR312WA02/03 are passive units designed for dedicated subwoofer applications - as partners for our active subwoofer units. Due to low mechanical losses they master equally well low level details and extreme dynamic requirements. For demanding sub bass applications using a passive unit is usually the only real alternative to sealed enclosures with active bass boost. To make experimenting and individual tuning convenient and easy, PR312WA02/03 are delivered with three separate extra loads that are easily applied onto a threaded rod on the rear side of the cone.
