Wavecor PR312WA02 PASSIVE MEMBRANE

Wavecor PR312WA02  PASSIVE MEMBRANE

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.

• 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)
