Wavecor WF559PA01 10.25" die cast frame, paper cone PA mid/woofer 8 Ohm
The 10¼” transducer WF259PA01 is the first product by Wavecor dedicated for Public Address audio systems.
It merges the well-know audiophile sound qualities of a typical Wavecor transducer with the common virtues of PA transducers with high sensitivity, high power handling, low distortion, and true-to-the-source sound reproduction.
FEATURES
- Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
- Alu shorting ring on center pole below and above air gap to reduce voice coil induction, reduce variation of voice coil induction as a function of voice coil position, and reduce flux variation induced by voice coil current. All with the purpose of reducing large-signal distortion
- Large motor with 3” voice coil diameter for better control and power handling
- Cone made of light and stiff paper formula for high efficiency and uncoloured sound
- Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
- Vented voice coil former for reduced distortion and compression
- Vented center pole with dual flares for reduced noise level and compression at large cone excursions
- Heavy-duty black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
- Low-loss suspension (high Qm) for better reproduction of details and dynamics
- Black plated motor parts for better heat transfer to the surrounding air
- Conex spider for better long-term stability and better durability under extreme conditions
