Emhlabeni wobuchwepheshe bomsindo, izingxenye ezimbalwa zihlonishwa futhi zibaluleke njengesistimu yomsindo ye-subwoofer. Kungakhathaliseki ukuthi ungumuntu olalelayo, uthanda i-movie, noma umlaleli nje ovamile, ama-subwoofers adlala indima ebalulekile ekuletheni umuzwa womsindo ogxilile. Manje-ke kuthiwani ngama-subwoofers awenza azwakale enamandla kangaka? Kulesi sihloko, sizohlola izinsimbi ezingemuva kwama-subwoofers, umthelela ezinawo kukhwalithi yomsindo, nokuthi kungani kufanele zibe nawo kunoma iyiphiisistimu yomsindo engathi sína.

Ukuqonda ama-Subwoofers

I-subwoofer yisipika esiklanyelwe ngokukhethekile ukukhiqiza kabusha imisindo yefrikhwensi ephansi, ngokuvamile ebangeni elingu-20 Hz ukuya ku-200 Hz. Lawa maza aphansi avame ukubizwa ngokuthi ama-bass, futhi abalulekile ekudaleni umuzwa ogcwele womsindo. Ngokungafani nezipikha ezijwayelekile, eziphatha imisindo ephakathi nendawo nephezulu, ama-subwoofers agxila ekugcineni okuphansi komsindo, okubalulekile ezinhlotsheni ezifana ne-hip-hop,umculo womdanso we-elekthronikhi, namamuvi agcwele izigameko.

Ama-Subwoofers aklanyelwe ukuthuthukisa ikhono lawo lokukhiqiza umsindo ojulile, ozwakalayo. Ama-subwoofers amaningi asebenzisa izigaxa ezinkulu kanye nozibuthe abanamandla ukuhambisa umoya kahle ukudala ukudlidliza esikubona njengebhesi. Lo mklamo ubenza bakwazi ukukhiqiza amaza omsindo angagcini nje ngokuzwakalayo, kodwa futhi agcwele futhi acwilisiwe.

I-Physics of Sound

Ukuze uqonde ukuthi ama-subwoofers angakhiqiza kanjani okunjaloumsindo onamandla, kufanele singene sijule ku-physics yamaza omsindo. Umsindo igagasi lomshini elihamba ngokudlidliza komoya (noma enye imidiya). Imvamisa yokudlidliza inquma ukuphakama komsindo, kuyilapho i-amplitude inquma ivolumu yomsindo.

Imisindo yefrikhwensi ephansi, njengalezo ezikhiqizwa i-subwoofer, zinamaza amade futhi zidinga amandla engeziwe ukuze zikhiqize. Ngenxa yalokhu, ama-subwoofers afakwe abashayeli abakhulu nama-amplifiers anamandla kunezipikha ezijwayelekile. Ikhono lokuhambisa umoya omkhulu linikeza ama-subwoofers umthelela wawo oyingqayizivele nokujula.

Umthelela womzwelo we-bass

Esinye sezizathu esenza ukuthi umsindo we-subwoofer ube namandla kakhulu yingoba ushukumisa inhliziyo. Amafrikhwensi aphansi anekhono eliyingqayizivele lokuhambisana nemizimba yethu, okwenza umuzwa wokuzwa ozwakala ungokoqobo njengokuwuzwa. Lokhu kuyiqiniso ikakhulukazi emculweni obukhoma, lapho i-bass ingabonakala ifika ngqo esifubeni sakho, ikhulise umuzwa wonke.

Kumamuvi nasemidlalweni, i-subwoofer ingakhuphula ukungezwani okungokomzwelo kwesigcawu. Cabanga ngomsindo wokuqhuma, noma ukushaya kwenhliziyo ngesikhathi esishubile; le misindo yenzelwe ukuthi izwakale ngokujulile ezithamelini. I-subwoofer ingakwazi ukukhiqiza kabusha lezi zikhathi eziphansi, yengeze ukujula ku-soundscape, yenze ukuzizwisa kugxile kakhulu futhi kuhehe.

Indima yama-subwoofers ezinhlelweni zethiyetha yasekhaya

Ama-Subwoofers abalulekile ku-auhlelo lweshashalazi yasekhaya. Banikeza ukwesekwa kwefrikhwensi ephansi, okubalulekile kumamuvi esenzo, agcwele ukuqhuma nemisindo ejulile. Ngaphandle kwe-subwoofer, le misindo ingabonakala iphansi futhi ingenawo umthelela onyakazisa inhliziyo.

Ukwengeza, ama-subwoofers asiza ukulinganisa umsindo ophelele wesistimu yetiyetha yasekhaya. Ngokuphatha amaza aphansi, avumela izikhulumi eziyinhloko ukuthi zigxile kububanzi befrikhwensi emaphakathi nephezulu, okuholela emsindweni ocacile, ohluke kakhulu. Lokhu kuhlukaniswa kwemvamisa akugcini nje ngokuthuthukisa ukucaca, kodwa futhi kuvimbela ukuhlanekezela ukuze uthole ukuzizwisa okujabulisayo kokulalela.

Ukukhetha OkulungileI-Subwoofer Sound System

Kunezici eziningana okufanele zicatshangelwe lapho ukhetha isistimu yomsindo we-subwoofer. Usayizi wegumbi, uhlobo lomsindo wokuqukethwe owujabulelayo, kanye nesabelomali sakho konke okucatshangelwayo okubalulekile. Igumbi elikhudlwana lingase lidinge i-subwoofer enamandla kakhulu ukuze igcwalise isikhala ngomsindo, kuyilapho igumbi elincane lingadinga imodeli ehlangene esaqhubeka.iletha ama-bass ahlaba umxhwele.

Ukwengeza, uhlobo lwe-subwoofer, kungakhathaliseki ukuthi i-passive noma inikwe amandla, luzothinta umuzwa wakho. Ama-subwoofers anamandla anama-amplifiers akhelwe ngaphakathi, okwenza kube lula ukusethwa nokusetshenziswa. I-Passive subwoofers, ngakolunye uhlangothi, idinga ii-amplifier yangaphandlekodwa unikeze izinketho eziningi zokwenza ngokwezifiso zama-audiophiles.

Ekuphetheni

Kunezizathu eziningi zokuthi kungani i-subwoofer izwakala inamandla. Ikhono layo lokukhiqiza kabusha amaza aphansi lidala umuzwa womsindo ocebile futhi ogxilile ohambisana nomlaleli ezingeni lomzwelo nelomzimba. Kungakhathaliseki ukuthi ubukele imuvi, ulalele umculo, noma udlala imidlalo yevidiyo, isistimu yomsindo yekhwalithi ye-subwoofer ingaphakamisa ulwazi lwakho, ikwenze kuhehe futhi kujabulise.

Njengoba ubuchwepheshe buqhubeka nokuvela, ama-subwoofers abe yinkimbinkimbi kakhulu, afakwe izici ezifana nokuxhuma okungenantambo nokulinganisa kwegumbi okuthuthukisiwe. Nokho, ukukhanga okuyisisekelo kwe-subwoofer kusalokhu kufana: ikhono layo lokuletha umsindo ojulile, ozwakalayo ohlabayo futhi osishukumisayo. Kunoma ngubani ozimisele ngomsindo, otshala imali ku-isistimu yomsindo yekhwalithi ephezulu ye-subwooferakukhona nje ukukhetha, kuyisidingo.
