RCF L15P400Professional 15" Woofer/Sub
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.
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 transducer's 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.
