Wavecor WF152BD08

Wavecor WF152BD08 Paper/Glass Fiber 8 Ohm

The 6” transducers WF152BD07 (4 ohm) and WF152BD08 (8 ohm) were designed as high performance bass and midrange units for very compact monitors and high-end hi-fi speakers.

FEATURES

• Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
• Copper cap on center pole to reduce voice coil inductance and to minimize variations in voice coil inductance as a function of voice coil position
• Cone made of a new paper/glass fiber mix with improved consistency and stability
• 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 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
• Large motor with 1¼” voice coil diameter for better control and power handling
• Built-in alu field-stabilizing ring for reduced distortion at high levels
• Low-loss suspension (high Qm) for better reproduction of details and dynamics
• Black motor parts for better heat transfer to the surrounding air
• Conex spider for better durability under extreme conditions
• Gold plated terminals to ensure long-term trouble free connection
