Wavecor WF118WA06 11,8cm glass fibre midwoofer 8 ohm

WF118WA05/06 are mid/woofers designed for demanding bass and midrange applications. They work equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups, etc.
Powered by a large 85 mm magnet structure that ensures good efficiency and optimal T/S parameters.
The large 32 mm voice coil ensures high power handling - thermally and mechanically
The new optimized woven glass fibre cone ensures large bandwidth and low distortion. Distortion is further reduced by efficient venting and by adding an internal alu shorting ring to  stabilize the magnetic field in the air gap

• New optimized glass fibre cone design
• Rigid steel chassis with extensive venting for lower air flow speed reducing audible distortion
• Vented center pole with dual flares for reduced noise level at large cone excursions
• Heavy-duty fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
• Large motor structure 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
• Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing
