Ikabhineti lesipikha sesathelayithi isipikha esincane esiklanyelwe ukukhiqiza umsindo ocacile nonemininingwane kuyilapho sithatha indawo encane egumbini lakho lokulalela. Ngokungafani nemibhoshongo emikhulu emi phansi, lezi zipikha ezincane ziklanyelwe ukubekwa phezu kwefenisha, zifakwe odongeni, noma zifakwe emashalofini ezincwadi, okwenza zibe ukukhethwa okuthandwayo kwezinhlelo zanamuhla zethelevishini zasekhaya. Zicishe zihlale zihlanganiswa ne-subwoofer, ephethe amaza omsindo ajulile angaphansi angakwazi ukuwenza izipikha ezincane ngokwazo. Lokhu kuhlukaniswa kwemisebenzi kuyinhliziyo yomqondo wesistimu yezipikha zesathelayithi, lapho ingxenye ngayinye igxila kububanzi bamaza omsindo ekwenza kahle kakhulu. I-OPA Co., Ltd., umkhiqizi ohamba phambili wemikhiqizo yomsindo enobuchwepheshe obunembile, ithuthukise lo mqondo ngeminyaka yocwaningo, ubuchwepheshe obuthuthukile bamadrayivu, nokulawulwa kwekhwalithi okuqinile. Kulo mhlahlandlela, sizohlola izinzuzo eziphezulu zezipikha zekabhineti zesathelayithi, izindlela ezingcono kakhulu zokuzisebenzisa, nezinto ezibalulekile okufanele zicatshangelwe ngaphambi kokuthenga. Ekugcineni, uzokwazi kahle ukuthi ungakha kanjani isistimu yomsindo encane kodwa enamandla edlula ezinye izindlela ezinkulu eziningi.

Isungulwe ngefilosofi yokuhlanganisa ubuchwepheshe nobuciko bezandla, i-OPA Co., Ltd. isikhule yaba igama elithembekile embonini ye-electroacoustic, isebenzela abathandi bomsindo nabaqondisi abangochwepheshe emhlabeni wonke. Onjiniyela benkampani banaka kakhulu yonke imininingwane, kusukela ekukhetheni izinto zokusetshenziswa kuya ekulungisweni kokugcina komsindo wecala ngalinye. Isipikha ngasinye se-cabinet satellite esiphuma endaweni ye-OPA sidlula ochungechungeni lokuhlola ukulalela nokuhlola izilinganiso okuqinisekisa ukusabela kwemvamisa okungaguquki nokusebenza okungenakuphazamiseka. Lokhu kuzibophezela kwekhwalithi yingakho imikhiqizo ye-OPA isetshenziswa emakamelweni okuhlala, ezitudiyo, nasezindaweni zokufaka ezentengiselwano emazweni amaningi. Noma ngabe uthuthukisa i-home theater yakho yokuqala noma udizayina indawo ekhethekile yokulalela, uhla lwe-OPA lunikeza izixazululo ezilinganisa ukusebenza, izindleko, nokuqina. Ukuze ufunde kabanzi ngenkampani engemuva kwalemikhiqizo, vakashela i-Mayelana Nathi ikhasi noma ulandele intuthuko yakamuva ku-Izindaba ikhasi.

Enye yezinzuzo ezisobala kakhulu zesipikha sekhabhinethi esiyisathelayithi ukuthi incane kakhulu, okwenza ifaneleke kahle ezindlini eziphakathi nendawo nezincane. Ipheya yalezi zipikha zingahlala kahle ku-consoli yemidiya, edeskini, noma eshalofini ngaphandle kokudla indawo ebonakalayo noma ukuvimba ukubukwa kukamabonakude wakho. Naphezu kobukhulu bazo obuncane, izipikha zesimanje eziyizisathelayithi zisebenzisa ama-driver ayinkimbinkimbi namabhokisi acushwe ngokucophelela ukuze zikhiphe ukusebenza okuqinile okumangalisayo. Ngenxa yokuthi isathelayithi ngayinye idinga ukukhiqiza kuphela imisindo ephakathi nephakeme kakhulu, onjiniyela bangakwazi ukwenza kahle idizayini ye-driver ukuze ijubane, icace, futhi ibe nomfanekiso omuhle kunokuba ikhiphe ubass oluhlaza. Lo mqondo wokuklama ogxilile yiwona kanye owenza izipikha ezincane zibe ukukhetha okuzenzakalelayo kubalaleli abacabanga ngesikhala abangavumi ukuyekela ikhwalithi yomsindo. Uma ufaka i-subwoofer ezinikele ukuthi iphathe amandla aphansi, inhlanganisela icishe iqhudelane nezinhlelo zezipikha ezinkulu kakhulu ngokungokoqobo nomthelela. Ngamanye amazwi, uthola umsindo wezinga le-theater ngaphandle kwamabhokisi amakhulu afana nefenisha.

Ukuguquguquka kokuklama kungenye inzuzo enkulu, ngoba izikhulumi ze-satellite zekhabhinethi zakhelwe ukuthi zinyamalale kunoma yiluphi uhlelo lwegumbi. Izinhlobo eziningi zihlanganisa ama-keyhole mounts noma ama-threaded inserts avumela ukuthi zifakwe odongeni eceleni kukamabonakude noma ngemva kwesofa ukuze zithole ama-surround channels. Izindlu ziyatholakala ngezinto zokuqeda eziphelelisa izindawo zangaphandle zesimanje, kusukela kumnyama omnyama nomhlophe kuya ku-wood-grain veneer efana nefenisha ekhona. Lokhu kuguquguquka kusho ukuthi awuphoqelekile ukuthi uhlele kabusha indawo yakho yokuhlala ngezinto zokulalela; esikhundleni salokho, izikhulumi ziyazijwayeza ikhaya lakho. Ukubekwa okuhambisana nefenisha, njengokubeka ipheya ekhabetheni eceleni kwe-turntable, kungenye yezindlela ezithandwa kakhulu abantu abasebenzisa ngazo lezi zikhulumi empilweni yansuku zonke. Noma ngabe uthanda ukubukeka okuncane noma ubuhle bendabuko obufudumele, kukhona umklamo we-satellite speaker ofanelana ngokwemvelo negumbi. Ukunaka kwe-OPA ekwakhiweni kwezindlu nasekhwalithi yokuqeda kuqinisekisa ukuthi izikhulumi zibukeka zisezingeni eliphezulu njengoba zizwakala.

Izinga eliphezulu lomsindo yisizathu sokuthi izipikha zesathelayithi zihlale zidumile naphezu kweminyaka eminingi yobuchwepheshe obuncintisanayo, futhi i-OPA iye yaphakamisa leli zinga lokusebenza nangaphezulu. Ubuchwepheshe obuthuthukile bama-driver, njengamakhoni alula enziwe ngephepha elashwa, nama-tweeter anedome kasilika, avumela lezi zipikha ezincane ukuthi zikhiqize amaphimbo aphezulu acwengekile kanye nephakathi elinemininingwane okwenza izinkulumo namazwi kuzwakale kungokwemvelo. Amabhokisi aqiniswe ngokucophelela anciphisa ukuduma okungafunwa, ngakho isipikha sikhiqiza isignali ngokunemba okuphawulekayo kunokwengeza umbala waso. Ukuhlolwa okuqinile kokuqina kusho ukuthi ama-satellite e-OPA aqhubeka nokusebenza ngokungaguquki ngisho nangemva kweminyaka yokusetshenziswa ngamavolumu aphezulu. Iyunithi ngayinye iyabhanqwa futhi iqondaniswe ngesikhathi sokukhiqiza ukuze isiteshi sobunxele nesokudla sizwakale sifana, okubalulekile ekwakheni umsindo we-stereo okholisayo kanye nomsindo ozungezile ongenazihibe. Kwabalaleli abazazisayo ukucaca, ukucaciseka, nokuzibandakanya ngokomzwelo emculweni nasefilimini, isipikha sekhabhinethi esiklanywe kahle sihlinzeka ngolwazi oludlula usayizi waso.

Ukusetshenziswa okudume kakhulu kwesipikha sekhabhinethi esiyisathelayithi ukubukwa kwamabhayisikobho ekhaya, lapho amasathelayithi amaningi amancane edala umsindo ozungezile ocwile. Kuhlelo lwe-2.1, amasathelayithi amabili abekwa ezinhlangothini zethelevishini yakho kanti i-subwoofer iphethe imisindo ephansi, okukunikeza ukuthuthuka okukhulu uma kuqhathaniswa nezipikha ezakhelwe ngaphakathi kuthelevishini ngentengo ephansi kakhulu. Uma ukhuphukela ohlelweni lwe-5.1, amasathelayithi amathathu aphatha isiteshi esimaphakathi nesangaphambili kanti amanye amabili amboza imiphumela esemaceleni nangemuva, kanti i-subwoofer iqinisa amaza omsindo aphansi. Emakamelweni amakhulu, ukuhlelwa kwe-7.1 kwengeza iziteshi ezimbili ezengeziwe zokuzungeza ukuze kube nokubekwa komsindo okunembe kakhulu nokushintsha okupholile. Ubuhle bezipikha ze-satellite ukuthi zingabekwa ukuze zihambisane nendlela ohleli ngayo, noma ngabe kusho ukufakwa odongeni kwalezo ezingemuva noma ukuzibeka ematafuleni aseceleni. Ngenxa yokuthi izipikha zincane futhi zilula, ukulungisa ukuhlelwa ukuze kutholakale umsindo omuhle kakhulu kungumsebenzi olula ongadingi ukuphakamisa izinto ezisindayo noma ukwakha okungapheli. Lokhu kukwazi ukukhula kwenza izinhlelo ze-satellite zibe yindlela evumelana nezimo kakhulu yokuthola umsindo we-cinema wangempela endaweni yasekhaya.

Ngaphezu kwezinhlelo eziphelele, izipikha zekhabhinethi ezincane zigqama njengeziteshi ezizungezile ezinikelwe kanye nezipikha ezinkulu ezingaphansi. Abathandi bomculo abaningi bakhetha izipikha ezinkulu ezingama-tower ngaphambili ukuze zithole umthelela omkhulu, kodwa ukusebenzisa izipikha ezincane ezingama-satellite ezinhlangothini nangemuva kugcina ukuzwakala kungaguquki ngaphandle kokugcwalisa igumbi. Izipikha ezingama-satellite zisebenza kahle kakhulu kule ndima ngoba izinto ezizungezile zingamaza kakhulu, okusho ukuthi izipikha zidinga ukusabalalisa okuhle kanye nokulinganisela kwethoni yemvelo kunokukhipha okwedlulele. Ukufaka izipikha ezincane odongeni ezingeni lezindlebe noma kancane ngaphezulu kwakha umbono oncomekayo womsindo ozungeza umlaleli, okuyilokho kanye abenzi bamafilimu abakuhlosile lapho behlanganisa amathrekhi azungezile. Le ndlela ehlanganisiwe ikuvumela ukuthi utshale imali yakho lapho kubaluleke kakhulu, ngenkathi usajabulela ulwazi olugcwele lwe-5.1 noma lwe-7.1. Futhi ikunikeza inkululeko yokukhulisa kancane kancane, ungeza izipikha ngazimbili ngesikhathi njengoba uhlelo lwakho lukhula.

Ukulalela kwe-desktop nokulalela eduze kungenye indlela enhle kakhulu yokusebenzisa, ikakhulukazi kubantu abasebenza ekhaya, abadlala imidlalo, noma abadlala ama-vinyl. Izipikha ezimbili ze-cabinet satellite ezibekwe phezu kwedeski, zixhunywe kukhompyutha noma ku-audio interface, ziletha umsindo ocacile ongenakufaniswa nama-headphones ngokomzimba nangokunethezeka. Abadlali bezinzuzo bathola izinkomba zendawo ezilethwa ama-satellite, okubasiza ukuthi babone izinyathelo nemiphumela yezinkomba emidlalweni yokuncintisana. Kwabanikazi be-turntable, ukwengeza ama-satellite amancane ane-subwoofer encane kuletha ukufudumala nokucacile emarekhodini ngaphandle kokudinga igumbi elikhulu elizinikele kwezomsindo. Ukubekwa eduze kusho ukuthi awudingi amandla amakhulu noma ama-driver amakhulu, ngoba izipikha zihlala eduze kwezindlebe zakho futhi yonke imininingwane emincane iyazwakala. Lolu hlelo luyafinyeleleka, luhlelekile, futhi lwanelisa ngokuphelele ekusetshenzisweni kwansuku zonke. Amakhasimende amaningi e-OPA asitshela ukuthi isistimu yabo ye-desktop iba ithuluzi lomsindo elisetshenziswa kakhulu ekhaya.

Ekugcineni, ukukhetha okuguquguqukayo kokubekwa kwesipikha sekhabhinethi yesathelayithi kusho ukuthi ungajabulela umsindo omuhle kungakhathaliseki ukuthi indlela yegumbi lakho noma ukuhlelwa kwefenisha kunjani. Izindawo zokuhlala ezivulekile, amagumbi anomumo ongajwayelekile, kanye nezindlu eziqashiswayo lapho ukubhola kungavunyelwe—konke kuzuza ekuguquguqukeni kwamasathelayithi amancane. Ungabeka amasathelayithi emashalofini ezincwadi, ngaphakathi kwamakhabhinethi emidiya, emafasiteleni, noma ezitendeni, inqobo nje uma uwagcina ekude nokuqiniswa kwe-bass enzima nokubonakala okuqondile. Ikhono lokuthambekisa izipikha zibheke endaweni yokulalela, kungaba ngama-bracket aguquguqukayo noma ama-foam wedge alula, liqinisekisa ukuthi uthola umfanekiso ohambisanayo noma ngabe uhlala kuphi. Lokhu kuzivumelanisa nezimo yikho okwenza abaklami bangaphakathi nochwepheshe bomsindo bobabili batuse izinhlelo zesathelayithi kumakhasimende afuna ukusebenza kahle ngaphandle kokudela isitayela. Noma ngabe isikhala sakho sinzima kangakanani, ukuzama kancane ngokubekwa kuvame ukuveza umsindo omuhle kakhulu.

Uma uthenga isipikha sekhabhinethi esiyisathelayithi, ikhwalithi yokwakhiwa kufanele ibe yinto yokuqala ocabanga ngayo ngoba ithinta ngqo kokubili ukuphila isikhathi eside nomsindo. Bheka izindawo ezenziwe ngezinto eziminyene ezifana ne-MDF noma i-molded composite, ezimelana nokudlidliza okungcolisa umphumela womsindo. Ukwakhiwa kwangaphakathi okuboshwe kahle kanye nezinsika zokuxhuma ezisezingeni eliphezulu ziyizimpawu zokuthi umkhiqizi unaka imininingwane ebalulekile. Ikhabhinethi kufanele izwe iqinile futhi isindile ngosayizi wayo, ingabi nokukhala noma ukungcangcazela okungenalutho uma uyithepha noma udlala umculo onamabhesi amaningi. Ukwakhiwa okuqinile kuphinde kuqinisekise ukuthi isipikha sisebenza ngokungaguquki eminyakeni yokusetshenziswa kwansuku zonke, okuyiyona nto yokuqina abanikazi be-OPA abaklama kuyo yonke imikhiqizo. Khumbula ukuthi ikhabhinethi iyisisekelo somsindo; indawo encane izokwehlisa noma amadrayivu amahle kakhulu.

Ikhwalithi yomsindo, kunjalo, iyinhloko yodaba, futhi isipikha esihle se-satellite kufanele sizwakale silinganiselwe, singathathi uhlangothi, futhi sinamandla ngale kwalokho usayizi waso ongase ukuphakamise. Naka indlela isipikha esisingatha ngayo amazwi nezinsimbi zomculo, ngoba i-midrange yilapho kuhlala khona ulwazi oluningi lomculo. Ama-high frequency kufanele abe nemininingwane futhi abe nomoya ngaphandle kokuba nesihluku noma ukuhlanza, futhi i-imaging kufanele ihlale izinzile uma usuka endleleni kancane. Ngenxa yokuthi i-subwoofer iphethe ama-bass ajulile, umsebenzi we-satellite uwukuletha imininingwane emihle ye-midrange ne-high frequency ngokuhlanekezela okuphansi emazingeni okulalela aphakathi. Bheka i-rated frequency response futhi ubheke idizayini ye-crossover ehlangana kahle nama-subwoofer avamile azungeze i-80 kuya ku-120 Hz. Lalela umlingiswa wemvelo, ongenambala ohlukanisa isipikha esenziwe kahle ngempela kunesimane esikhwazimulayo.

Ukuzibophezela kwe-OPA ekufaneni kusho ukuthi wonke amakhabhinethi amasipiki esathelayithi ekukhiqizweni okukodwa azwakala ngendlela efanayo, okubaluleke kakhulu uma ufaka amasipiki amahlanu noma ayisikhombisa ohlelweni lwe-surround. Inkampani ikala iyunithi ngayinye emishinini yokuhlola emisindo elinganiswe kahle futhi ihlanganisa ama-driver anokubekezeleka okuqinile ngaphambi kokuhlanganiswa. Lokhu kuqinisekiswa kwekhwalithi kuqinisekisa ukuthi ukutshalwa kwakho imali kuletha ukusebenza okuthembekile nokubikezelwayo kunoma yikuphi ukuhlelwa. Uma ukhetha i-OPA, awuthengi nje isipikha; uthenga izinga lobunjiniyela elisekelwa iminyaka yocwaningo lwe-electroacoustic. Ukuzinikela kwenkampani ekubonakaleni nakho kudlulela enkonzweni yamakhasimende, lapho ochwepheshe betholakala ukukusiza ukhethe ukuhlelwa okufanele kwegumbi lakho. Ukuze uthole umbono wohlu olugcwele lwemikhiqizo namanani, vakashela i-Imikhiqizo ikhasi, futhi ngezixazululo ezenziwe ngokwezidingo zakho, hlola Yenza ngokwezifiso insiza ukuze ube nohlelo olwakhiwe ngokwezidingo zakho ngqo.

Impendulo emfushane ngu-yebo: ukuze uthole imiphumela engcono kakhulu, isipikha sekhabhinethi esiyisathelayithi kufanele sihlanganiswe ne-subwoofer, futhi abakhiqizi abaningi baklama amasistimu abo ngalokhu kulindeleka engqondweni. Amasathelayithi ngamabomu mancane, okusho ukuthi ama-driver awo awakwazi ukuhambisa umoya owanele ukuze akhiqize amabhasi ajulile ngevolumu enengqondo. Ngaphandle kwe-subwoofer, isistimu yesathelayithi izozwakala izacile, ingenawo ubunzima nomthelela okwenza amamuvi nomculo kujabulise. Ukwengeza i-subwoofer kuqedela ububanzi befrikhwensi, kuvumela amasathelayithi ukuthi adlale amafrikhwensi awabelwe wona ngaphandle kokucindezeleka futhi kwehlise ukuhlanekezela okuphelele. Ama-subwoofer anamuhla aphinde abhekele umsindo ophansi oshikizayo wekamelo owenza izigcawu zesenzo zibe nomdlalo omkhulu, umsebenzi izipikha ezincane okungafanele ziwuzame. Umphumela uwumuzwa wohla olugcwele ozwakala mkhulu kakhulu kunosayizi wangempela wempahla.

Kwabantu abaningi, uhlelo lwe-2.1 lwezinkanyezi ezimbili kanye ne-subwoofer lunikeza ibhalansi engcono kakhulu yezindleko, ukusebenza, nokulula. Luthuthukisa umsindo kamabonakude kakhulu, lusebenza kahle kakhulu ekusakazeni umculo, futhi lungena kahle kunoma yiliphi igumbi. Uma ufuna ukuzizwa okugcwele kwe-cinematic, ukucushwa kwe-5.1 kwengeza isiteshi esimaphakathi sokuthola ingxoxo ecacile kanye nezinkanyezi ze-surround zemiphumela yezindawo, kudala ulwazi lwakudala lwe-home theater ngentengo efanelekile. Lokhu kucushwa kuyafinyeleleka, kunemininingwane, futhi kulungele igumbi, yingakho kubusa izimakethe zokuqala nezaphakathi. Ungaqala ngisho nge-2.1 bese ukwandisa ukuya ku-5.1 kamuva, ngoba izipikha ze-satellite ze-OPA ziklanyelwe ukuthi zixutshwe futhi zifaniswe kulo lonke uhla lomkhiqizo. Le ndlela yokuthuthukisa ivikela utshalomali lwakho futhi ivumela uhlelo lwakho ukuthi lukhule nesabelomali sakho nendawo yakho.

Uma i-subwoofer ngempela ingenakwenzeka, noma ngabe ngenxa yomakhelwane, izinkinga zegumbi, noma isabelomali esiqinile, unezinye izindlela ongazicabangela. Izipikha ze-bookshelf ezigcwele ububanzi noma izipikha zemibhoshongo ezinama-woofer amakhulu zingakhiqiza i-bass eningi ngokwazo, nakuba zinkulu futhi zibiza kakhulu. Ipheya yezipikha ze-bookshelf ezisezingeni elihle inganelisa abalaleli abajwayelekile abajabulela kakhulu umculo we-acoustic nokuqukethwe okugcwele ingxoxo ngamavolumu aphakathi. Nokho, umzuzu obuka i-movie yesenzo noma ulalela umculo ogcwele i-bass, umehluko uyabonakala, futhi cishe uzofisa ukuthi ubungeze i-subwoofer. Uma uthathe le ndlela, khetha izipikha ze-bookshelf ezinempendulo ende ye-low-frequency futhi ugweme ukukhulisa i-bass ngokusebenzisa i-equalization, okwandisa nje ukuhlanekezela. Kodwa kubathengi abaningi, indlela ehlakaniphile ukuhlela i-subwoofer kusukela ekuqaleni futhi ujabulele ububanzi obugcwele bedynamic range obuyivula.

Izinkunzi ze-OPA cabinet satellite ziletha umsindo wezinga le-audiophile ngoba zihlanganisa izingxenye zekhwalithi ephezulu nobuchwepheshe obucophelelayo kuzo zonke izigaba zokukhiqiza. Ama-driver atholakala kubakhiqizi abathembekile futhi ahlolwa ngokuqinile, kuyilapho ama-crossover eklanyelwe ukuhlanganisa kahle phakathi kwama-driver ne-subwoofer. Umphumela ukwethulwa okuhambisanayo, okungokwemvelo okwembula imininingwane ekurekhodweni ngaphandle kokweqisa noma ukukhathaza. Ithimba lobunjiniyela le-OPA liqhubeka nokuthuthukisa imiklamo ngokusekelwe ezilinganisweni nasezinqunjini zokulalela, liqinisekisa ukuthi isizukulwane ngasinye esisha sithuthuka kunesedlule. Noma ngabe usakaza umsindo ongalahleki, ubuka ifilimu enkulu, noma udlala irekhodi oyithandayo, ama-satellite e-OPA embula inhloso yomculi nomqondisi. Leli zinga lokusebenza lichaza ukuthi kungani i-OPA ithenjwa abathandi bomculo emhlabeni wonke, kusukela kwabathengi bokuqala kuya kubahlaziyi abanokuhlangenwe nakho.

Ukukwazi ukuthenga kuyingxenye eyinhloko yenani le-OPA, ngoba inkampani ikholelwa ukuthi umsindo omuhle akufanele udinge ukubolekwa kwemali enkulu. Ngokulawula inqubo yokukhiqiza, ukuthola izinto zokusebenza ngendlela efanele, nokuthengisa ngezindlela eziqondile, i-OPA inikeza amanani ancintisanayo ngaphandle kokudela ikhwalithi. Uthola amazinga okwakha nokusebenza kwemikhiqizo ebiza kakhulu, yingakho imikhiqizo ihlala ithola izincomo eziqinile zomlomo nomlomo. Ukwesekwa kwamakhasimende okuzinikele nesiqinisekiso esiqinile kunikeza ukuthula kwengqondo, futhi ithimba liphendula ngokushesha emibuzweni mayelana nokumisa, ukubeka, nokuhlanganisa. Uma ungaqiniseki ukuthi iyiphi imodeli efanele igumbi lakho, ochwepheshe bomsindo be-OPA bazokwenza
