IL PREZZO SI RIFERISCE AL SINGOLO WOOFER.
Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 15-inch trasducer wtihin its application range.
The L15P400 uses a fibre 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 reachees its maximum excursion limits.Forced air venting system.
