WOOFER
Response curve recorded in anechoic chamber (Free-field, 4 pi radiation) with 0.5m microphone distance. The
loudspeaker is mounted in a closed box of 7 l net. volume.
L14RCY/P
L14RCY/P is a 5" High Fidelity woofer unit with a stiff and stable
injection moulded metal chassis. The stiff, yet light aluminium
cone and the low loss rubber surround show no sign of the familiar
500-1500 Hz cone edge resonance and distortion associated with soft
cones. On the other hand, the cone break up modes at higher frequencies
call for special attention in the crossover design work. A high temperature
voice coil wound on an aluminium voice coil former gives a high power
handling capacity. The phase plug gives low compression due to
temperature variations in the voice coil, high power handling capacity and
eliminates resonances which would otherwise occur in the volume between
the dust cap and the pole piece. The L14RCY/P is equipped with a heavy
magnet structure for improved efficiency and voice coil control.
