I-tweeter yesipikha esinezindlela ezimbili inomsebenzi obalulekile webhendi yonke yamafrikhwensi aphezulu. Ingxenye yayo ye-tweeter yesikhulumi ithwala wonke amandla engxenye ephezulu ye-high-frequency, ukuze wenze le tweeter ingalayishiwe, ngakho awukwazi ukukhetha i-tweeter enephuzu eliphansi le-crossover, uma ukhetha iphuzu eliphansi le-crossover lizoholela ku-tweeter ku-tweeter kuyoba ngamandla amakhulu kakhulu, okuzoholela ekutheni i-tweeter ishiswe, ngaphansi kwezimo ezijwayelekile, i-tweeter 0 ngeke ibe ngaphezu kwe-crossover 20!

I-tweeter kufanele futhi isetshenziswe ngokuhambisana ne-woofer. Ngesikhathi esifanayo, sidinga futhi ukucabangela umkhawulo we-tweeter-frequency ephansi, ngaphandle kwalokho, kuzoba nokukhuluma kabi kwamafrikhwensi amabili. Umkhawulo wefrikhwensi yesipika esingu-6.5-intshi ngokuvamile awubi ngaphezu kuka-5,000 Hz, uma siklama iphoyinti le-crossover, uma sishiya ukuphindwa kabili kwe-frequency, khona-ke leli phuzu le-crossover lephuzu eliphusile lithatha inani elicishe libe ngu-2.5000 Hz, ngokufanayo, umkhawulo wefrikhwensi ephansi ye-tweeter, uma futhi i-dou kufanele ibe ngaphansi kwe-dou ye-frequency ukuze ibale imvamisa efanayo. 1.2500 Hz. Phinda kabili imvamisa yokubala, kufanele ibe ngaphansi kuka-1.2500 Hz.

Ngezidingo ze-tweeter, okokuqala, imvamisa ye-resonant F0 ayikwazi ukuba ngaphezu kwengxenye ye-frequency yephoyinti le-crossover, ngaphandle kwalokho, kuzoholela endaweni ye-crossover endaweni yokuphendula imvamisa kuzoba yinkinga, uhla olufanele kufanele kube imvamisa ye-resonant yesipika ayiphezulu kune-1.2500 Hz. Uma ubukhulu be-woofer obusekela bungaphansi kwama-intshi angu-6.5, kuleli phuzu, umkhawulo we-tweeter we-low-frequency uzobe uphakeme kancane, ngoba ngalesi sikhathi ikhono le-woofer high-frequency lizothuthukiswa, iphuzu le-crossover lizophakanyiswa, lokhu kusekelwe ezicini ze-woofer ukunquma!

Lapho sikhetha i-tweeter, sidinga futhi ukunaka ukuthi ukuzwela, ngokuyisisekelo ukuzwela kwe-tweeter akukwazi ukuba ngaphansi kokuzwela kwe-woofer. Uma iphansi kunayo, kuzoba nzima ukunciphisa ukuzwela kwesipikha ngokusebenzisa ukuncishiswa kwesipikha esijwayelekile, uma i-crossover ye-electronic, lokhu akubalulekile, lapho ukuzwela kwe-tweeter kungaphezu kokuzwela kwezipikha ze-bass, singakwazi ngokusebenzisa i-tweeter ochungechungeni lwama-resistors ahlanganisa izinsiza ezivimbelayo ukunciphisa kokubili ukuze kuzuzwe inhlanganisela ephelele ye-treble.

Into yokugcina okumele siyiveze ukuthi izici ze-tweeter ngokwayo zinomthelela omkhulu kakhulu ohlelweni lonke, ngakho-ke kufanele sihambe futhi sikhethe i-tweeter ngokuhlanekezela okuphansi nokusebenza kahle!
