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.
FEATURES
Extremely rigid alu cone for precise transient response
Rigid die cast chassis with extensive venting for lower air flow speed reducing audible distortion
Low-loss suspension (high Qm) for better reproduction of details and dynamics
Conex spider for better durability under extreme conditions
Custom tunable by adding one or more of the three extra weights (included)
