RCF LF18N401 18-inch woofer
Product no: KO-LF18N401 Bax Music Warranty: This product comes with a 3-year warranty.

General

The LF18N401 is equipped with a 4-inch voice coil, which means it's a real powerhouse. The 18-inch woofer is optimally suited for reproducing low frequencies, as as such should be used in a subwoofer cabinet, where it can perform at its best. The woofer can effortlessly produce 1,200 watts of continuous power, as long as it gets the right frequencies in the right surroundings. Different simulation programs can help to develop a fitting subwoofer cabinet that follows the Thielle/Small parameters.
