Wavecor WF275BD02 Glass Fiber High End Bass 10"

Wavecor WF275BD02 Glass Fiber High End Bass 10"

The 10.75” transducers WF275BD01 (4 ohm) and WF275BD02 (8 ohm) were designed as high performance bass/midrange units for monitors and high-end hi-fi speakers. They offer outstanding extended bass performance and overall dynamic and detailed reproduction.
Ideal for multi-way constructions they additionally offer designers the rare opportunity of working with 10” 2-way solutions if paired with a suitable tweeter, like for instance some of the Wavecor 30 mm units.

• 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 and compressions 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 39 mm 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 plated 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
