{"product_id":"rcf-sub18-as","title":"RCF SUB18-AS Portable 18\" Active Subwoofer for Live Sound","description":"\u003cp\u003eThe RCF SUB18-AS is built for sound engineers and production companies running portable live sound systems in small to mid-sized venues. Its 2200-watt Class-D amplifier drives an 18\" woofer to a peak output of 135 dB SPL, providing the low-end headroom needed for music playback, corporate events, club installs, and touring packages where a single subwoofer must anchor the entire system.\u003c\/p\u003e\u003cp\u003eThe SUB18-AS is designed to integrate directly with 10\", 12\", or 15\" full-range loudspeakers. Stereo XLR crossover outputs route the high-pass signal to tops without requiring an external processor, and the Bass Motion Control algorithm extends usable bass response at all drive levels without sacrificing reliability. The rear panel puts volume, polarity, and low-pass frequency selection within reach during setup, reducing dependency on a separate system controller.\u003c\/p\u003e\u003cp\u003eThe Baltic birch plywood cabinet with polyurea coating withstands the rigors of repeated load-in and load-out. Two side handles and an M20 pole-mount thread give crews multiple deployment options, whether ground-stacked or flown on a pole above a satellite speaker. For engineers choosing between this and competing 18\" powered subs, the combination of onboard DSP controls, convection cooling, and a road-grade cabinet makes the SUB18-AS a practical choice where simplicity and output consistency matter most.\u003c\/p\u003e","brand":"RCF USA, Inc.","offers":[{"title":"Default Title","offer_id":52450861449400,"sku":"143278","price":2299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/143278_RCF-SUB18-AS-Portable-18_-Active-Subwoofer-for-Live-Sound_ALT01sqr.jpg?v=1786584316","url":"https:\/\/soundpro.com\/products\/rcf-sub18-as","provider":"SoundPro","version":"1.0","type":"link"}
