RCF L15P400 Low Frequency Replacement Woofer – 15 Inch

Get Low Distortion With the RCF L15P400 Low Frequency Replacement Woofer – 15 Inch

Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 15-inch transducer within its application range. The L15P400 uses a fiber loaded cone assembly along with a high excursion triple roll surround. This combination provides remarkable strength and a peak to peak maximum excursion of 52mm. The T-pole also features RCF Precision’s spaced gap demodulation technology, progressively braking the voice coil, providing a much smoother transition for the moving mass as it reaches its maximum excursion limits. Forced air venting system.
