Features
- 4-inch, fiberglass inside/outside copper voice coil
- 1600W continuous program power handling
- 97 dB Sensitivity
- 30 Hz – 1.5 kHz Frequency range
- Aluminum demodulation ring
- Forced air ventilation and 14mm top plate for minimum power compression
- Dual spider design with silicon based dampening control
- Triple-roll surround and corrugated straight cone geometry
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.
