Wavecor WF152BD09 Kevlar Carbon cone 14 cm 4 ohm midwoofer

The 6” transducers WF152BD09 (round, 4 ohm), WF152BD10 (truncated, 4 ohm), WF152BD11 (round, 8 ohm), and WF152BD12 (truncated, 8 ohm) were 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

• Vented voice coil former for reduced distortion and compression

• 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
