{"product_id":"stage9-rcf-tts-56a","title":"RCF TTS 56-A Dual 21-inch Active Subwoofer with RDNet | Touring","description":"The RCF TTS 56-A is a high-output, dual 21-inch active subwoofer built for large-format sound reinforcement where punch, depth and control are essential. A powerful Class-D amplifier drives two long-excursion transducers to deliver extended low-frequency performance with excellent headroom, clarity and transient response. Integrated DSP ensures precise crossover, limiting and voicing, while RDNet networking enables detailed control, system optimisation and real-time monitoring across complex deployments.\n\nEngineered for touring reliability, the robust cabinet and reinforced grille withstand the demands of the road, with ergonomics that support efficient handling, stacking and rigging. The TTS 56-A integrates seamlessly with RCF large-format systems and supports cardioid or end-fire arrays for improved low-frequency directivity, reduced stage spill and a cleaner onstage environment. From modern live music and EDM to stadium-scale playback and arena installations, it delivers authoritative sub-bass that remains tight and musical at high SPL.\n\nIdeal for touring sound companies, festival main stages, arenas and high-impact fixed installs requiring powerful, controllable and scalable low-frequency reinforcement.\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRCF TTS 56-A Dual 21-inch Active Subwoofer with RDNet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE9.5.100.200\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"RCF","offers":[{"title":"Used Equipment","offer_id":57401421496697,"sku":null,"price":5978.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/rcf-tts-56a_04648-768x731.jpg?v=1780928504","url":"https:\/\/stage-experts.com\/products\/stage9-rcf-tts-56a","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
