{"product_id":"rcf-lf12g301","title":"RCF 12\" Woofer High-Power Replacement Driver | LF12G301","description":"\u003cp\u003eThe RCF LF12G301 is a 12\" woofer built for audio professionals who need a reliable, high-output replacement or OEM driver in live sound reinforcement and installed speaker systems. With 450W RMS power handling and 900W program capacity, it is engineered to sustain demanding continuous operation without the thermal or mechanical failure common in lower-grade drivers. The 97 dB sensitivity rating means amplifiers work efficiently, which matters in both touring rigs where headroom is critical and fixed installations where amplifier headroom is limited by system design.\u003c\/p\u003e\u003cp\u003eThe driver uses a 3-inch fiberglass inside\/outside copper voice coil wound on a 76 mm former, paired with an M-roll polycotton surround and a curved exponential cone geometry. These construction choices work together to minimize distortion at high excursion while maintaining consistent frequency response across the rated 40 Hz to 2 kHz range. Ceramic magnet motor and a 10 mm top plate contribute to the high Bl factor of 19 T x m, delivering strong control over cone movement. For integrators building custom enclosures, the full Thiele-Small parameter set is documented, enabling accurate box modeling in ported or bandpass alignments.\u003c\/p\u003e\u003cp\u003eCE compliance confirms the driver meets European safety standards, and the published mounting dimensions simplify drop-in cabinet integration. Whether used as a factory replacement in an RCF cabinet or as the foundation of a custom system build, the LF12G301 provides the power handling and transducer accuracy that professional applications require.\u003c\/p\u003e","brand":"RCF USA, Inc.","offers":[{"title":"Default Title","offer_id":52451224223928,"sku":"113821","price":269.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/113821_RCF-12_-Woofer-High-Power-Replacement-Driver-_-LF12G301_ALT01sqr.jpg?v=1786581682","url":"https:\/\/soundpro.com\/products\/rcf-lf12g301","provider":"SoundPro","version":"1.0","type":"link"}
