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
