The BMC method creates a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that limits over-excursions. Traditional high-pass filters protect the woofer from over-excursion but change the phase\/frequency response. In contrast, the new BMC algorithm protects the woofer allowing total freedom of signal reproduction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNew Perspective on Linearity\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eKX speakers are designed using a proprietary and advanced digital FiR technology, conceived to deliver transparent sound, absolute clarity, and perfect imaging to the listener. The special FiRPHASE processing distributes sound to all listeners without phase distortions, ensuring minimum latencies in the system. The algorithm corrects phase and amplitude (if necessary) by taking into account the weak points of the transducers and the resonances or cancellations due to the cabinet of the loudspeaker.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAcoustical:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 50 Hz – 20,000 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMax SPL @ 1m:\u003c\/strong\u003e 137 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHorizontal Coverage Angle:\u003c\/strong\u003e 100°\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVertical Coverage Angle:\u003c\/strong\u003e 70°\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTransducers:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompression Driver:\u003c\/strong\u003e 1.4\" neo, 4.0\" v.c\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWoofer:\u003c\/strong\u003e 1 × 15\" neo, 3.5\" v.c\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput \/ Output Section:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Signal:\u003c\/strong\u003e Balanced \/ Unbalanced\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Connectors:\u003c\/strong\u003e XLR, RDNet Ethercon\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Connectors:\u003c\/strong\u003e XLR, RDNet Ethercon\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e –2 dBu \/ +4 dBu\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProcessor Section:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCrossover Frequency:\u003c\/strong\u003e 750 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProtections:\u003c\/strong\u003e Thermal, HF\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLimiter:\u003c\/strong\u003e Fast Limiter\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eControls\u003c\/strong\u003e: Gain reduction, processing, 8 selectable presets\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRDNet:\u003c\/strong\u003e Onboard\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Section:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTotal Power:\u003c\/strong\u003e 3200 W Peak\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Frequencies:\u003c\/strong\u003e 1200 W Peak\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow Frequencies:\u003c\/strong\u003e 2000 W Peak\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCooling:\u003c\/strong\u003e Convection\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConnections:\u003c\/strong\u003e Powercon TRUE1 TOP IN\/OUT\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStandard Compliance:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSafety Agency:\u003c\/strong\u003e CE Compliant\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCabinet Material:\u003c\/strong\u003e Baltic birch plywood\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHardware:\u003c\/strong\u003e Quick-lock, pole mount, 3 × M10 on top, 3 × M10 on bottom sides\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHandles:\u003c\/strong\u003e 2 × Side\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePole Mount \/ Cap:\u003c\/strong\u003e 35 mm insert\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrille:\u003c\/strong\u003e Steel with cloth backing\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Height:\u003c\/strong\u003e 705 mm \/ 27.76 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Width:\u003c\/strong\u003e 419.6 mm \/ 16.52 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Depth:\u003c\/strong\u003e 430 mm \/ 16.93 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 28.4 kg \/ 62.61 lbs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Height:\u003c\/strong\u003e 801 mm \/ 31.54 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Width:\u003c\/strong\u003e 484 mm \/ 19.06 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Depth:\u003c\/strong\u003e 474 mm \/ 18.66 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 32 kg \/ 70.55 lbs.\u003c\/p\u003e","brand":"RCF","offers":[{"title":"Default Title","offer_id":46883772530941,"sku":"H-RCF-KX45A","price":6599.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/2308\/3005\/files\/2097374.jpg?v=1763404184","url":"https:\/\/hollywooddj.com\/products\/rcf-kx-45-a-speaker","provider":"Hollywood DJ","version":"1.0","type":"link"}
