The L15P200AK-II is teh RCF classical extended low Frequency 15" woofer. Generous voice coil length, heavier moving mass weight and very low resonance for perfect low frequency reproduction. Remarkable the linearity in the application range. Special treatments are applied to cone surface and surround for optimum dampening.
Features 4-inch, fiberglass inside/outside copper voice coil 1600W continuous program power handling 95 dB Sensitivity 35 Hz - 1 kHz Frequency range Triple-roll damped surround Corrugated straight damped cone Dual spider designed with silicon based damping control
