Woofer 15", 800W AES, 1600W Program |  |
|
|
|
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 LF15X400 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 52 mm. 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.
Applications
The LF15X400 is ideal for use in applications whereincredible power handling, long excursion and perfect control is required. Ideal for high quality professional bass reflex and bass-horn systems, 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 systems. |
