Casse Acustiche

Una cassa acustica o diffusore acustico è un sistema di uno o più altoparlanti che trasformano il segnale elettrico proveniente da un amplificatore audio in suono.
Le più comuni casse acustiche sono basate su di un sistema a due vie, dove il woofer riproduce le tonalità basse e il tweeter le tonalità alte. Le frequenze audio vengono divise dal crossover.
I diffusori acustici possono essere attivi, sistemi acustici dotati di un amplificatore, o passivi sistemi acusitici che hanno bisogno di un amplificatore per funzionare.
Le caratteristiche principali che determinano la qualità di un diffusore acustico sono:
La risposta in frequenza, l'efficienza, la sensibilità, l'impedenza, la frequenza di risonanza e la potenza massima che si misura in potenza di picco e potenza RMS.
Le casse acustiche vengono abitualmente utilizzate con dei dei Subwoofer che sono degli altoparlanti dedicati alla riproduzione di suoni a bassa frequenza.
In questa categoria troverete casse acustiche amplificate e casse acustiche passive di diverse potenze, casse per karaoke, casse portatili, casse da incasso, casse monitor, e tante altre tipologie.
