Wavecor Speaker Driver - PR259WA01 10¼" Die Cast Alu Cone Passive Radiator
Description
The PR259WA01 is a passive unit designed for dedicated subwoofer applications - as partner for our active subwoofer units. Due to low mechanical losses it masters 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, PR259WA01 is delivered with three separate extra loads that are easily applied onto a threaded rod on the rear side of the cone.
Features
- New optimized outer suspension (surround) for improved large-signal handling
- 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)
