Ama-Subwoofers asephenduke into ebaluleke kakhulu yezinhlelo zokulalelwayo zesimanje, umculo ophakamisayo, amamuvi, kanye nolwazi lokudlala ngamabhesi awo ajulile, anomsindo. Ukuqonda ubunkimbinkimbi bendlela ama-subwoofers asebenza ngayo, izinzuzo nemikhawulo yawo, nokuthi ungawakhetha futhi uwasebenzise kanjani ngempumelelo kungathuthukisa kakhulu umuzwa wakho wokulalela. Lesi sihloko sidingida kukho konke odinga ukukwazi mayelana nama-subwoofers, ukuhlinzeka ngemininingwane yabo bobabili ama-audiophiles nabalaleli abavamile ngokufanayo.

Iyini i-subwoofer?
I-subwoofer iwuhlobo lwesipika esidizayinelwe ukukhiqiza kabusha amaza omsindo anezwi eliphansi aziwa ngokuthi i-bass ne-sub-bass, ephansi kunalokho okungakhiqizwa izipikha ezijwayelekile. Ama-Subwoofers ahlanganisa ububanzi ngokuvamile obusuka ku-20 Hz ukuya ku-200 Hz emikhiqizweni yabathengi, okungaphezu kwalokho izipikha ezijwayelekile ezithatha izintambo. Ziyingxenye ebalulekile ezinhlelweni zemisindo ezungezile kanye nokuzuza umuzwa womsindo ophelele, ikakhulukazi kumathiyetha asekhaya, amasistimu omsindo wemoto, nezinhlelo zamakheli omphakathi.
Ama-Subwoofers afika ngosayizi abahlukahlukene, kusukela kumayunithi ahlangene angafihlwa kude ngaphansi kwefenisha kuya kumamodeli amakhulu aphansi angaba ingqikithi yokusethwa komsindo. Idizayini yabo ihlanganisa umshayeli omkhulu (ingxenye yesipika enyakazayo ukuze idale umsindo) efakwe kukhabethe eklanyelwe ukuthuthukisa ukukhiqizwa komsindo wemvamisa ephansi. Lokhu kugxila kumafrikhwensi aphansi kuvumela ama-subwoofers ukuthi akhiqize imisindo ejulile, eshayayo ongase uyizwe kaningi njengokuyizwa.
Isebenza kanjani i-subwoofer?
Ama-Subwoofers asebenza ngokuguqula amasignali kagesi abe ukunyakaza komzimba ukuze akhiqize amaza omsindo. Inhliziyo ye-subwoofer ingumshayeli wayo noma i-woofer—i-diaphragm enkulu ehamba phambili naphambili ukuze iphushe umoya futhi idale amaza omsindo. Lokhu kunyakaza kukhiqizwa inqubo kazibuthe kagesi efaka ikhoyili yezwi elenga endaweni kazibuthe. Uma isignali yomsindo idluliswa kukhoyili, idonsa inkambu kazibuthe esebenzisana nozibuthe ohlala njalo oyizungezile, okwenza ikhoyili, kanjalo ne-diaphragm, inyakaze.
Idizayini yendawo ebiyelwe ye-subwoofer idlala indima ebalulekile ekusebenzeni kwayo. Kunezinhlobo ezimbalwa zezivalo ze-subwoofer, okuhlanganisa okuvalwe uphawu, okufakwe ngesandla, kanye ne-bandpass, ngayinye inikezela ngezici ezihlukile ngokuya ngokusebenza kahle, ukusabela kwemvamisa, kanye nekhwalithi yomsindo iyonke. Ivolumu nokuma kwendawo ebiyelwe kubalwa ngokucophelela ukuze kufane nezicaciso zomshayeli ukuze kukhuliswe ukusebenza kahle okuphelele kwesistimu futhi kuncishiswe ukuhlanekezela.
Izinzuzo kanye nezithiyo ze-subwoofer
Ama-Subwoofers aletha izinzuzo eziningi ohlelweni lomsindo. Zinikeza ukujula nokunotha komsindo izipikha ezincane ezingakwazi ukuwufinyelela, okuvumela abalaleli ukuthi bazizwele i-spectrum egcwele yomculo namathrekhi omsindo, okuhlanganisa amafrikhwensi ebhesi aphansi kakhulu. Lokhu kungadala umuzwa wokulalela ogxile kakhulu, noma ngabe ubukele imuvi, ulalela umculo, noma udlala igeyimu yevidiyo. Ukwengeza, ngokuphatha amaza e-bass, ama-subwoofers akhulula izipikha ezincane ohlelweni ekukhiqizeni kabusha le misindo enzima, okuholela ekukhanyeni, okuningiliziwe kwamafrikhwensi amaphakathi naphezulu.
Kodwa-ke, ama-subwoofers nawo anezinkinga zawo. Zingaba zinkulu futhi kube nzima ukuzihlanganisa ezindaweni zokuhlala ezincane ngobuhle. Ukubeka ngendlela efanele kubalulekile ekusebenzeni okuhle, futhi ukuthola indawo efanele kungaba inselele. Ngaphezu kwalokho, ama-subwoofers aklanywe kabi noma asethwe ngokungalungile angaholela ku-boomy noma i-bass engalawuleki edlula yonke i-spectrum yomsindo, kunokuba igcwalise.
Ungakhetha kanjani i-subwoofer
Ukukhetha i-subwoofer efanele kuhilela ukucabangela izici ezimbalwa, okuhlanganisa ubukhulu, amandla, uhlobo lwendawo ebiyelwe, nezinketho zokuxhuma. Ubukhulu bekamelo kanye nokusetshenziswa okuyinhloko kwe-subwoofer (umculo, amamuvi, noma okuncane kwakho konke) kuzobeka amandla nosayizi we-subwoofer oyidingayo. Amagumbi amakhudlwana nalabo abafuna ukuzizwisa okufana ne-cinema bangase bazuze kuma-subwoofers amakhulu, anamandla, kuyilapho amagumbi amancane noma labo abathanda umculo ngokuyinhloko bengase bakhethe iyunithi ehlangene, enamandla kakhulu.
Uhlobo lwendawo ebiyelwe nalo luwukucatshangelwa okubalulekile. Izivalo ezivaliwe zinikeza amabhesi aqinile, anembe kakhudlwana, kuyilapho izivalo eziphothiwe kanye ne-bandpass zingakhiqiza ivolumu eyengeziwe kanye nolwazi olugcwele lwebhesi kodwa zingadela ukunemba okuthile. Ukwengeza, cabanga ukuthi udinga i-subwoofer enamandla (ene-amplifier eyakhelwe ngaphakathi) noma i-subwoofer engenzi lutho (edinga i-amplifier yangaphandle), ukhumbula izinketho zokuxhuma ngesistimu yakho yomsindo ekhona.
Ungayisebenzisa kanjani i-subwoofer
Ukusetha kahle nokusebenzisa i-subwoofer kungathuthukisa kakhulu ukusebenza kwayo. Ukubekwa kuyisihluthulelo; indawo ekahle incike kuma-acoustics nesakhiwo segumbi. Linga ngezindawo ezihlukene, ukhumbula ukuthi amakhona angakwazi ukukhulisa i-bass kodwa angase ayidilize. Uma usuyitholile indawo elungile, lungisa imvamisa ye-crossover—iphuzu lapho i-subwoofer yakho ithatha khona imisebenzi ye-bass evela kuzipikha zakho—ukuqinisekisa ukushintshwa komsindo okungenazihibe. Okokugcina, lungisa kahle ivolumu nezilawuli zesigaba ukuze zifane nesistimu yakho yonke, uhlose umsindo olinganiselayo ohlanganisa i-bass ngokushelelayo namafrikhwensi aphakathi nendawo naphezulu.
Isiphetho:
Ama-Subwoofers angamathuluzi anamandla kunoma yikuphi ukusethwa komsindo, akwazi ukuletha ukujula, ukunotha, nokucwiliswa kumuzwa wakho wokulalela. Ukuqonda ukuthi zisebenza kanjani, izinzuzo zazo nokulinganiselwa kwazo, nokuthi ungazikhetha kanjani futhi uzisebenzise kanjani ngempumelelo kungakusiza uvule amandla azo aphelele. Kungakhathaliseki ukuthi ungumdlali we-audiophile ofuna umsindo ophelele noma ufuna nje ukuthuthukisa isistimu yakho yokuzijabulisa yasekhaya, i-subwoofer ekhethwe kahle futhi emiswe kahle ingenza umehluko omkhulu.
