CA25RE4
CA25RE4 is a 10" High Fidelity woofer with an injection moulded
metal chassis. This unit has excellent mechanical matching between
paper cone, paper dust cap and low loss rubber surround. A special
treatment of the cone together with a four layer voice coil provide a
well behaved roll off characteristic and reduce 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.
