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 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 Precisions 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.
Applications:
The L15P400 is ideal for use in applications where incredible power handling,long excursion and perfect control is required.
Ideal for high quality professional bass reflex and bass-horn system, incredible when used in double 15" subwoofer configuration.
The transducers low frequency extension, coupled with its extremely low generation of harmonic distortion,also makes it ideal for use within critical listening applications such as studio monitoring subwoofer system.
