Rcf LF18N401 18-in Woofer W/neodymium Transducer, The Lowest Power Compression, 8 Ohms 2400 Watts Max [single]

This item is brand-new, factory sealed.

Incredibly linear frequency response characteristics,the highest power handling of any comparable 18-in ch neodymium transducer, the lowest power compression.
The LF18N401 uses a fibre loaded cone assembly along w/a high excursion triple roll,constant geometry surround.
This combination provides remarkablestrength venting system guarantee a very efficient voice coil ventilation for minimum power compression & higher power handling.
* The LF18N401 is ideal for use in applications where incredible power handling is required,long excursion & light weight.
* Specially designedfor touring,perfect for high quality professional bass reflex & bass-horn system.
* The transducer's low frequency extension & control also makes it ideal for use within critical listening applications as studio monitoring subwoofer system.
