RCF LF21N451 21-inch woofer
Product no: KO-LF21N451 Bax Music Warranty: This product comes with a 3-year warranty.

General

This 21-inch woofer from RCF's LF series is a high-capacity, efficient speaker that was designed to offer powerful, detailed sub-bass frequencies without using too much power. The L21P451 makes use of a fibreglass cone and has a T-pole design, which ensures a minimal amount of flux modulation. The dual-force ventilation system ensures efficient voice coil ventilation for minimising power compression. It has a frequency range of 30 Hz to 1 kHz.

This subwoofer is ideal for applications that require a lightweight device with high power capacity and BL. It is great for use on tour, in sub-bass reflex designs.
