Wavecor WF259PA01 10 1/4″ die cast frame, paper cone PA mid/woofers, 8Ohm

Overview:

The 10.25” transducers WF259PA01 (8 ohm) was the first products by Wavecor dedicated for Public Address audio systems. They merge the well-known 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
