{"product_id":"rcf-sub18-ax-w","title":"RCF SUB 18-AX Portable Active Subwoofer With DSP | White","description":"\u003cp\u003eThe RCF SUB 18-AX is built for production engineers and rental companies running small to mid-sized live sound systems. It pairs a latest-generation 18-inch transducer with a 2200W peak Class-D amplifier in a bass-reflex, polyurea-coated plywood cabinet, giving touring and portable-install operators a rugged box that handles daily deployment without sacrificing output or clarity. The 135 dB max SPL ceiling and onboard Bass Motion Control excursion management keep the driver safe even at extended high-output sets, which matters in club, festival side-stage, and corporate event contexts where subs run hard for hours.\u003c\/p\u003e\u003cp\u003eWhat separates the SUB 18-AX from comparable powered subs in its class is the depth of its integrated DSP. Dual crossovers with recallable presets, 8-band parametric EQ, signal routing, configurable delays, and cardioid deployment presets allow a single engineer to manage an entire PA stack from inside the subwoofer itself, reducing the need for a separate drive rack. The color touch panel and encoder give fast on-box access, while Bluetooth connectivity and the RCF LiveRemote app extend full parameter control to a mobile device for front-of-house adjustments without leaving the mix position.\u003c\/p\u003e\u003cp\u003eThe cabinet supports M20 pole mounting for satellite speaker integration and ships with dual XLR\/TRS combo inputs, a link output, dual XLR crossover outputs, and a sealed Powercon True1 Top AC connector for secure, locking power in live environments. Side handles simplify one-person transport between stage and transport. The SUB 18-AX is the right subwoofer when a compact footprint, professional DSP depth, and reliable field performance all need to come from the same box.\u003c\/p\u003e","brand":"RCF USA, Inc.","offers":[{"title":"Default Title","offer_id":52450861416632,"sku":"143277","price":2399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/143277_RCF-SUB-18-AX-Portable-Active-Subwoofer-With-DSP-_-White_ALT12sqr.jpg?v=1786584397","url":"https:\/\/soundpro.com\/products\/rcf-sub18-ax-w","provider":"SoundPro","version":"1.0","type":"link"}
