Inzwi rinoshandiswa nemutauri rinotsanangurwa se simba rekuburitsa ruzha rakakamurwa nesimba remagetsi. Mitauro yakawanda yemutauri haibatsiri; inenge 1% yesimba remagetsi rinotumirwa ne amplifier kumutauri wemba wemba inoshandurwa kuita simba rekunzwika. Zvasara zvinoshandurwa kuita kupisa, kunyanya muzwi coil nemagineti gungano. Chikonzero chikuru cheizvi ndechekuoma kwekuwana kukodzera impedance kuenderana pakati pe acoustic impedance yeiyo drive unit nemhepo yainopisa mukati. (Pane yakaderera frequency, kuvandudza iyi mechi ndicho chinangwa chikuru chematauriri ekuvhara matauriri). Kubudirira kwematauriri ematauriri kunosiyana ne frequency. Semuenzaniso, kuburitsa kwewoofer mutyairi kunodzikira sezvo frequency inodzikira nekuda kwekuwedzera kushomeka pakati pemhepo inoenderana uye mutyairi wemutauri. Mubvunzo: Chii chinotsanangura kushanda?
