Com seu ímã de ferrite, bobina de grande diâmetro e mecânica reforçada (suspensão e spiders), ele visa uma utilização em SUB ou em grave\/infra conforme a arquitetura do seu alto-falante e o crossover. É uma escolha pertinente quando se busca um 18 polegadas capaz de entregar graves densos, limpos e duradouros, tanto em configuração móvel quanto em instalação fixa.\u003c\/p\u003e\u003ch3\u003ePara quem é o B\u0026amp;C 18RBX100?\u003c\/h3\u003e\u003cp\u003eEste alto-falante de 18 polegadas é destinado a integradores, fabricantes de caixas, locadores, prestadores de serviço e entusiastas do DIY que desejam \u003cstrong\u003eremembranar\u003c\/strong\u003e uma caixa ou \u003cstrong\u003econstruir\u003c\/strong\u003e um subwoofer bass-reflex coerente em torno de um transdutor com alta resistência à potência. É especialmente adequado para sistemas de sonorização onde se espera uma pressão acústica significativa: música eletrônica, shows ao vivo, clubes, eventos, fachadas ou reforço de graves. Sua carga recomendada e seus parâmetros eletromecânicos (Fs, Qts, Xmax) permitem partir de uma base confiável para dimensionar uma caixa e uma sintonia adequadas.\u003c\/p\u003e\u003ch3\u003eConcepção e elementos-chave: para graves profundos, controlados e duradouros\u003c\/h3\u003e\u003ch4\u003eBobina de 100 mm e motor de ferrite: a combinação \"potência + controle\"\u003c\/h4\u003e\u003cp\u003eA bobina móvel de 4,0 polegadas (100 mm) em fio de cobre é dimensionada para suportar regimes elevados, mantendo um bom controle do movimento. Associada a um motor com \u003cstrong\u003eímã de ferrite\u003c\/strong\u003e, ela visa uma resposta de graves estável e resistência mecânica adequada às solicitações típicas de um sub (grandes excursões, nível contínuo, transitórios).\u003c\/p\u003e\u003ch4\u003eSuspensão de duplo rolamento, duplo spider siliconado: estabilidade mecânica em grande deslocamento\u003c\/h4\u003e\u003cp\u003ePara um 18 polegadas destinado ao sub, a mecânica faz a diferença. Aqui, a \u003cstrong\u003esuspensão de duplo rolamento\u003c\/strong\u003e e o \u003cstrong\u003eduplo spider siliconado\u003c\/strong\u003e contribuem para a estabilidade do conjunto móvel e a regularidade do comportamento quando o nível aumenta. Resultado: graves mais limpos, menos sujeitos a desvios mecânicos e maior tranquilidade na operação.\u003c\/p\u003e\u003ch4\u003eCone curvilíneo tratado: uma membrana pensada para palco e campo\u003c\/h4\u003e\u003cp\u003eO cone curvilíneo recebe um \u003cstrong\u003etratamento impermeável\u003c\/strong\u003e aplicado na frente e atrás. Este elemento é apreciado para aplicações de sonorização, onde as condições podem variar (transporte, umidade, exigências de uso). O tratamento também contribui para a constância da membrana ao longo do tempo, mantendo o objetivo principal: entregar uma base sólida e boa projeção nas baixas frequências.\u003c\/p\u003e\n\n\u003ch2\u003eEspecificações técnicas\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
