Kungakhathaliseki ukuthi udlala ama-drum solo emotweni yakho, uhlela uhlelo lwakho lweshashalazi lwasekhaya ukuze ubukele i-movie entsha ye-Avengers, noma wakha uhlelo lwe-stereo lwebhendi yakho, cishe ufuna leyo bass ejulile nemnandi. Ukuze uthole lo msindo, udinga i-subwoofer.

I-subwoofer uhlobo lwesipikha esikhiqiza i-bass njenge-bass ne-sub-bass. I-subwoofer izothatha isignali yomsindo ephansi bese iyiguqula ibe umsindo i-subwoofer engakwazi ukuwukhiqiza.

Uma uhlelo lwakho lwesipikha luhlelwe kahle, ungazwa umsindo ojulile nocebile. Isebenza kanjani i-subwoofer? Yimaphi ama-subwoofer amahle kakhulu, futhi ingabe anomthelela omkhulu kangaka ohlelweni lwakho lomsindo? Nakhu okudingeka ukwazi.

Kuyinii-subwoofer?

Uma une-subwoofer, kumele kube ne-subwoofer eyodwa, akunjalo? kulungile. Ama-woofers amaningi noma izikhulumi ezivamile zingakhiqiza umsindo ofinyelela ku-50 Hz kuphela. I-subwoofer ikhiqiza umsindo ophansi ofinyelela ku-20 Hz. Ngakho-ke, igama elithi “subwoofer” livela ekubhongeni okuphansi okwenziwa yizinja lapho zikhonkotha.

Nakuba umehluko phakathi komkhawulo wama-50 Hz wezikhulumi eziningi kanye nomkhawulo wama-20 Hz we-subwoofer ungase uzwakale ungabalulekile, imiphumela iyabonakala. I-subwoofer ikuvumela ukuthi uzwe i-bass engomeni nasefilimini, noma yini enye oyilalele. Uma impendulo ye-subwoofer iphansi, i-bass izoba namandla futhi ibe mnandi kakhulu.

Njengoba la mathoni ephansi kakhulu, abanye abantu abakwazi ngisho nokuzwa i-bass evela kwi-subwoofer. Yingakho ingxenye yokuzizwa ye-subwoofer ibaluleke kangaka.

Izindlebe ezincane neziphilile zizwa imisindo ephansi njenge-20 Hz kuphela, okusho ukuthi izindlebe eziseminyakeni ephakathi ngezinye izikhathi ziyahluleka ukuzwa imisindo ejulile kangaka. Nge-subwoofer, uzokuzwa ukudlidliza noma ungakuzwa.

Isebenza kanjani i-subwoofer?

I-subwoofer ixhuma kwezinye izipikha ohlelweni lomsindo oluphelele. Uma udlala umculo ekhaya, cishe une-subwoofer exhunywe kwisamukeli sakho somsindo. Uma umculo udlalwa ngezipikha, ithumela imisindo ephansi kwi-subwoofer ukuze iphindaphindeke kahle.

Uma kukhulunywa ngokuqonda ukuthi ama-subwoofer asebenza kanjani, ungase uhlangane nezinhlobo ezisebenzayo nezingasebenzi. I-subwoofer esebenzayo ine-amplifier eyakhelwe ngaphakathi. Ama-subwoofer angasebenzi adinga i-amplifier yangaphandle. Uma ukhetha ukusebenzisa i-subwoofer esebenzayo, kuzodingeka uthenge ikhebula le-subwoofer, njengoba kuzodingeka ulixhume ku-receiver yesistimu yomsindo, njengoba kuchaziwe ngenhla.

Uzoqaphela ukuthi ohlelweni lomsindo lwethiyetha yasekhaya, i-subwoofer iyisikhulumi esikhulu kunazo zonke. Ingabe esikhulu singcono? Yebo! Uma isikhulumi se-subwoofer sikhulu, kulapho umsindo ujula khona. Izikhulumi ezinkulu kuphela ezingakhiqiza imisindo ejulile oyizwayo kwi-subwoofer.

Kuthiwani ngokudlidliza? Lokhu kusebenza kanjani? Ukusebenza kahle kwe-subwoofer kuncike kakhulu endaweni yayo. Onjiniyela bomsindo abangochwepheshe batusa ukubeka ama-subwoofer:

Ngaphansi kwefenisha. Uma ufuna ngempela ukuzwa ukudlidliza komsindo ojulile nocebile wefilimu noma umculo, ukuwubeka ngaphansi kwefenisha yakho, njengesofa noma isihlalo, kungathuthukisa leyo mizwa.

eduze kodonga. Beka eyakhoibhokisi le-subwoofereduze kodonga ukuze umsindo uzwakale odongeni futhi ukhuphule i-bass.

Indlela yokukhetha i-subwoofer engcono kakhulu

Njengezipikha ezivamile, izici ze-subwoofer zingathinta inqubo yokuthenga. Kuye ngokuthi ufunani, nakhu okufanele ukubheke.

Ibanga Lokuvama

Imvamisa ephansi kakhulu ye-subwoofer umsindo ophansi kakhulu umshayeli wesipikha angawukhiqiza. Imvamisa ephezulu kakhulu umsindo ophakeme kakhulu umshayeli angawuthola. Ama-subwoofer amahle kakhulu akhiqiza umsindo ofinyelela ku-20 Hz, kodwa umuntu kufanele abheke ububanzi bemvamisa ukuze abone ukuthi i-subwoofer ingena kanjani ohlelweni lwe-stereo iyonke.

Ukuzwela

Uma ubheka izici zama-subwoofers athandwayo, bheka ukuzwela. Lokhu kubonisa ukuthi kudinga amandla angakanani ukukhiqiza umsindo othize. Uma ukuzwela kuphakeme, kulapho amandla amancane i-subwoofer ewadingayo ukukhiqiza i-bass efanayo nesipikha sezinga elifanayo.

Uhlobo lwekhabhinethi

Ama-subwoofers ahlanganisiwe asevele akhelwe ebhokisini le-subwoofer avame ukukunikeza umsindo ojulile nogcwele kunengavaliwe. Ikesi elinezimbobo lingcono emisindweni ephakeme, kodwa hhayi ngempela imisindo ejulile.

Ukuphazamiseka

Impedance, elinganiswa ngama-ohms, ihlobene nokumelana kwedivayisi nogesi ngomthombo womsindo. Ama-subwoofers amaningi anempedance engama-ohms angu-4, kodwa ungathola nama-subwoofers angu-2 ohm kanye nama-ohms angu-8.

Ikhoyili yezwi

Ama-subwoofers amaningi eza ne-voice coil eyodwa, kodwa abathandi bomsindo abanolwazi noma abashisekayo bavame ukukhetha ama-subwoofers amabili e-voice coil. Ngama-voice coil amabili, ungaxhuma uhlelo lomsindo njengoba ubona kufanele.

Amandla

Uma ukhetha i-subwoofer engcono kakhulu, qiniseka ukuthi ubheka isilinganiso samandla. Ku-subwoofer, isilinganiso samandla se-RMS sibaluleke kakhulu kunesilinganiso samandla aphezulu. Lokhu kungenxa yokuthi silinganisa amandla aqhubekayo kunamandla aphezulu. Uma usuvele une-amplifier, qiniseka ukuthi i-subwoofer oyibhekile ingakwazi ukusingatha lokho kukhishwa kwamandla.
