Woofer 15", 900W AES, 1800W Program |  |
|
|
Incredibly linear frequency response characteristics, the highest power handling of any comparable 15-inch neodymium transducer, the lower power compression.
The LF15N401 uses a fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround. This combination provides remarkable strength and a peak to peak maximum excursion of 52 mm. The unique Dual-forced air venting system guarantee a very efficient voice coil ventilation for minimum power compression and higher power handling.
Applications
The LF15N401 is ideal for use in applications where incredible power handling, long excursion and light weight is required. Specially designed for touring, perfect for high quality professional bass reflex and bass-horn systems. The transducer’s low frequency extension and control also makes it ideal for use within critical listening applications such as studio monitoring subwoofer systems. |
