I-tweeter yesipikha esinezindlela ezimbili ithwala umsebenzi obalulekile webhendi yonke yemvamisa ephezulu. Ingxenye yayo ye-tweeter yesipikha ithwala wonke amandla engxenye yemvamisa ephezulu, ukuze le tweeter ingagcwali ngokweqile, ngakho awukwazi ukukhetha i-tweeter enephuzu eliphansi le-crossover, uma ukhetha iphuzu eliphansi le-crossover kuzoholela ekutheni i-tweeter idlule emandleni amakhulu kakhulu, okuzoholela ekutheni i-tweeter ishiswe, ngaphansi kwezimo ezijwayelekile, iphuzu le-crossover le-tweeter ngeke libe ngaphezu kwama-hertz angu-2,000!

I-tweeter kufanele futhi isetshenziswe kanye ne-woofer. Ngesikhathi esifanayo, sidinga futhi ukucabangela umkhawulo wemvamisa ephansi ye-tweeter, ngaphandle kwalokho, kuzoba nokungezwani kahle kwama-frequency amabili. Umkhawulo wemvamisa ephezulu wesipikha esingu-6.5 intshi ngokuvamile awuphakeme kune-5,000 Hz, uma siklama iphuzu le-crossover, uma sishiya ukuphindaphindwa kwemvamisa, khona-ke leli phuzu le-crossover le-reactant lithatha inani elingaba ngu-2.5000 Hz, ngokufanayo, umkhawulo wemvamisa ephansi ye-tweeter, uma futhi ngokusho okufanayo shiya ukuphindaphindwa kwemvamisa ukuze kubalwe, khona-ke kufanele kube ngaphansi kwe-1.2500 Hz. Phinda kabili imvamisa ukuze kubalwe, kufanele kube ngaphansi kwe-1.2500 Hz.

Ngokwezidingo ze-tweeter, okokuqala, imvamisa ye-resonant F0 ayikwazi ukuba ngaphezu kwengxenye yemvamisa yephuzu le-crossover, ngaphandle kwalokho, kuzoholela endaweni ye-crossover lapho impendulo yemvamisa izoba yinkinga, ububanzi obufanele kufanele bube imvamisa ye-resonant yesipikha ingekho ngaphezu kwe-1.2500 Hz. Uma usayizi we-woofer osekelayo ungaphansi kwamasentimitha angu-6.5, kuleli qophelo, umkhawulo wemvamisa ephansi we-tweeter uzoba phezulu kancane, ngoba kuleli qophelo ikhono le-woofer lemvamisa ephezulu lizothuthukiswa, iphuzu le-crossover lizophakanyiswa, lokhu kusekelwe ezicini ze-woofer ukuze zinqunywe!

Lapho sikhetha i-tweeter, sidinga futhi ukunaka ukuzwela, ngokomthetho ukuzwela kwe-tweeter akunakuba ngaphansi kokuzwela kwe-woofer. Uma iphansi kunayo, kuzoba nzima ukunciphisa ukuzwela kwesipika ngokusebenzisa ukuncishiswa kwesipika okuvamile, uma kwenzeka i-electronic crossover, lokhu akubalulekile, lapho ukuzwela kwe-tweeter kuphakeme kunokuzwela kwezipikha ze-bass, singakwazi ukusebenzisa i-tweeter ochungechungeni lwama-resistor athile aqukethe ezinye izikhungo zokuvimbela ukunciphisa lokhu okubili ukuze kufezwe inhlanganisela ephelele ye-treble ne-bass.

Into yokugcina okufanele siyisho ukuthi izici ze-tweeter uqobo zinomthelela omkhulu kakhulu kulo lonke uhlelo, ngakho-ke kumelwe sikhethe i-tweeter enokuphazamiseka okuncane nokusebenza okuhle!
