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 20 l net volume.
CA21RE4X/DC
CA21RE4X/DC is an 8" High Fidelity woofer with an injection moulded
metal chassis. This unit has excellent mechanical matching between a
paper cone, a paper dust cap and a low loss rubber surround. A special
treatment of the cone produces a well behaved roll off characteristic and
reduces potential resonance problems. The magnet system has a T-shaped
cross section of the pole piece for low modulation distortion.
A relatively large voice coil diameter gives a high power handling capacity.
The double 2 layer voice coil with separate terminals makes it usable as a
common woofer with two satellite speakers, taking two stereo signals below
e.g. 150 Hz. This unit offers new possibilities in response shaping when
used as a woofer in a one channel speaker. A large magnet system provides
high efficiency and low Q.
