WOOFER
P25REX
P25REX is a 10" High Fidelity woofer with an injection moulded metal
chassis. Careful matching between a polypropylene cone, a polypropylene
dust cap and a low loss rubber surround yields a smooth frequency
response with a well behaved roll off. 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. This unit is
also available with our patented Dynamic Damping (DD), which improves
low bass transient behaviour at high power levels: (P25REX/DD H 308).
