Il principio coassiale (motore HF al centro del cono LF) favorisce una \u003cstrong\u003ecoerenza temporale\u003c\/strong\u003e e una direttività più leggibile rispetto a un montaggio con trasduttori separati, un vantaggio chiave quando si mira a una cassa discreta, versatile e facile da posizionare. Grazie alla sua architettura e al magnete in \u003cstrong\u003eneodimio\u003c\/strong\u003e, questo modello risponde alle esigenze dei sistemi moderni: prestazioni, peso contenuto e integrazione semplificata.\u003c\/p\u003e \u003ch3\u003ePer quali usi e profili?\u003c\/h3\u003e\u003cp\u003eQuesto diffusore coassiale da 21 cm è particolarmente adatto alla progettazione di casse \u003cstrong\u003epoint source\u003c\/strong\u003e compatte: monitor da palco, piccole facciate, rinforzo di prossimità, casse per installazioni fisse (bar, sale polivalenti, luoghi di culto) o sistemi portatili ad alto rendimento. La sua \u003cstrong\u003ebanda passante da 70 Hz a 18 kHz\u003c\/strong\u003e e la \u003cstrong\u003ecopertura di 100 gradi\u003c\/strong\u003e ne fanno una base solida per un progetto che cerca una diffusione ampia e una buona intelligibilità.\u003c\/p\u003e\u003cp\u003eSi adatta ai progettisti di casse DIY esigenti, agli integratori e ai produttori che vogliono un trasduttore capace di performare bene sia sulla voce sia su programmi musicali dinamici, mantenendo una direttività stabile e un ingombro compatto.\u003c\/p\u003e \u003ch3\u003eProgettazione, motorizzazione e prestazioni: ciò che fa la differenza\u003c\/h3\u003e\u003ch4\u003eArchitettura coassiale e direttività\u003c\/h4\u003e\u003cp\u003eIl 8CXN51 combina un altoparlante \u003cstrong\u003eLF 8\" (21 cm)\u003c\/strong\u003e e una sezione \u003cstrong\u003eHF 0,79\" (circa 20 mm)\u003c\/strong\u003e nello stesso insieme, per un comportamento da \u003cstrong\u003esorgente unica\u003c\/strong\u003e. Questo approccio facilita la taratura acustica e contribuisce a un'immagine più stabile, soprattutto in ascolto ravvicinato o quando la cassa è posizionata fuori asse. La \u003cstrong\u003ecopertura di 100 gradi\u003c\/strong\u003e mira a una dispersione confortevole per spazi vari, mantenendo una buona presenza.\u003c\/p\u003e \u003ch4\u003eTenuta in potenza ed efficienza\u003c\/h4\u003e\u003cp\u003eCon \u003cstrong\u003e500 W AES\u003c\/strong\u003e sulla sezione bassa e \u003cstrong\u003e100 W AES\u003c\/strong\u003e sulla sezione alta (impedenze \u003cstrong\u003e8 + 8 Ohm\u003c\/strong\u003e ), questo coassiale è progettato per sostenere livelli elevati. Le sensibilità dichiarate, \u003cstrong\u003e97 dB (LF)\u003c\/strong\u003e e \u003cstrong\u003e104 dB (HF)\u003c\/strong\u003e a 1 W \/ 1 m, permettono di puntare a un eccellente rapporto livello\/ingombro, particolarmente interessante per casse compatte da sonorizzazione.\u003c\/p\u003e \u003ch4\u003eMateriali e affidabilità in uso professionale\u003c\/h4\u003e\u003cp\u003eLa sezione bassa dispone di una \u003cstrong\u003ebobina mobile da 51 mm\u003c\/strong\u003e con \u003cstrong\u003efilo in alluminio\u003c\/strong\u003e e di una \u003cstrong\u003esospensione LF a doppio rollio\u003c\/strong\u003e, un insieme orientato a robustezza e controllo dello spostamento. Il \u003cstrong\u003eXmax di 6,0 mm\u003c\/strong\u003e contribuisce alla tenuta nelle basse frequenze per un 21 cm, e il \u003cstrong\u003eQts di 0,27\u003c\/strong\u003e favorisce allineamenti efficaci in carico accordato.\u003c\/p\u003e\u003cp\u003ePer gli alti, la sezione HF si basa su una \u003cstrong\u003ebobina da 44 mm\u003c\/strong\u003e e un \u003cstrong\u003ediaframma in poliimmide\u003c\/strong\u003e, una scelta pertinente per combinare precisione e durata. Il cono è di tipo \u003cstrong\u003eesponenziale\u003c\/strong\u003e con un \u003cstrong\u003etrattamento impermeabile sulla parte frontale\u003c\/strong\u003e, utile quando la cassa deve lavorare in condizioni impegnative (trasporto, umidità occasionale, uso intensivo).\u003c\/p\u003e \u003ch4\u003eOttimizzazione in cassa: carico raccomandato\u003c\/h4\u003e\u003cp\u003ePer facilitare lo sviluppo, è fornita un'indicazione di carico: \u003cstrong\u003e15 litri\u003c\/strong\u003e con un \u003cstrong\u003eaccordo a 75 Hz\u003c\/strong\u003e. Questo orienta chiaramente il 8CXN51 verso casse compatte, capaci di erogare un basso pulito e rapido, lasciando la possibilità di aggiungere un subwoofer se l'applicazione richiede più estensione sotto i 70 Hz.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifiche tecniche\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr) minmax(0,1fr)}table[data-wb-spec] colgroup{display:none}table[data-wb-spec] tbody,table[data-wb-spec] tr{display:contents}table[data-wb-spec] td{display:block;overflow-wrap:anywhere;grid-row:var(--wb-l);background-color:var(--wb-lb)}table[data-wb-spec] td[data-r]{grid-row:var(--wb-r);background-color:var(--wb-rb)}table[data-wb-spec] td[colspan=\"2\"]{grid-column:1\/-1}table[data-wb-spec] td:empty{display:none}}\u003c\/style\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:3;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eMontabile a Rack\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eNo\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eTipo\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eAltoparlanti\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:2;--wb-r:4;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCategoria\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eAccessori Sonorizzazione\u003c\/td\u003e\u003ctd data-r colspan=\"2\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:11;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eModello\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eB\u0026amp;C 8CXN51\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eDiaframma\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003epoliimmide\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:2;--wb-r:12;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eDiametro\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e8\u0026quot;
