Wavecor WF275BD02 10" die cast paper/glass fiber cone 8 Ohm
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.
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 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
