Wavecor WF182BD13 7″ die cast, Kevlar/Carbon fibre cone mid/woofers 4Ohms

OVERVIEW:

The 7” transducers WF182BD13 (round, 4 ohm) was designed as high performance bass and midrange units for compact monitors and high-end hi-fi speakers.

FEATURES:

• New cone of interwoven Kevlar/Carbon fibers, a new reference for the combination of low mass, rigidness, and damping – highly beneficial properties for midrange reproduction
• Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
• Vented, inverted center dome for reduced compression
• 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
• Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
• Heavy-duty black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
• Large motor with 1.25” 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
