Kungakhathaliseki ukuthi udlala isigubhu sodwa emotweni yakho, umisa isistimu yetiyetha yasekhaya ukuze ubuke i-movie entsha ye-Avengers, noma wakhela ibhendi yakho isistimu ye-stereo, cishe ufuna leyo bhesi ejulile, enamanzi.Ukuze uthole lo msindo, udinga i-subwoofer.

I-subwoofer iwuhlobo lwesipika esikhiqiza kabusha i-bass njenge-bass ne-sub-bass.I-subwoofer izothatha isignali yomsindo enezwi eliphansi futhi iyiguqule ibe umsindo i-subwoofer engakwazi ukuyikhiqiza.

Uma isistimu yakho yesipikha isethwe kahle, ungathola umsindo ojulile, ocebile.Isebenza kanjani i-subwoofer?yiphi i-subwoofer ehamba phambili, futhi ingabe inomthelela omkhulu kangako kusistimu yakho yomsindo iyonke?Nakhu okudingeka ukwazi.

Yini ai-subwoofer?

Uma une-subwoofer, kufanele kube ne-subwoofer eyodwa ngaphezulu, akunjalo?kulungile.Ama-woofer amaningi noma izipikha ezijwayelekile zingakhiqiza kuphela umsindo wehle ufike cishe ku-50 Hz.I-subwoofer ikhiqiza umsindo ophansi we-frequency kuze kufike ku-20 Hz.Ngakho-ke, igama elithi "subwoofer" livela ekukhaleni okuphansi okwenziwa izinja lapho zikhonkotha.

Nakuba umehluko phakathi komkhawulo ongu-50 Hz wezipikha eziningi kanye nomkhawulo we-subwoofer ongu-20 Hz ungase uzwakale ungabalulekile, imiphumela iyabonakala.I-subwoofer ikuvumela ukuthi uzwe i-bass engomeni nakumuvi, nanoma yini enye oyilalelayo.Ukusabela okuphansi kwemvamisa ephansi ye-subwoofer, i-bass izoba namandla futhi ibe namanzi amaningi.

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

Izindlebe ezincane, ezinempilo zingezwa kuphela imisindo ephansi njengo-20 Hz, okusho ukuthi izindlebe ezineminyaka ephakathi kwesinye isikhathi ziyanzima ukuzwa imisindo ejule kangako.Nge-subwoofer, uqinisekile ukuthi uzokuzwa ukudlidliza noma ungakuzwa.

Isebenza kanjani i-subwoofer?

I-subwoofer ixhuma kwezinye izikhulumi ohlelweni oluphelele lomsindo.Uma udlala umculo ekhaya, cishe une-subwoofer exhunywe kumamukeli wakho womsindo.Uma umculo udlalwa ngezipikha, uthumela imisindo ephansi ku-subwoofer ukuze ikhiqize kabusha ngempumelelo.

Uma kuziwa ekuqondeni ukuthi ama-subwoofers asebenza kanjani, ungase uhlangabezane nezinhlobo zombili ezisebenzayo nezingenzi lutho.I-subwoofer esebenzayo ine-amplifier eyakhelwe ngaphakathi.I-Passive subwoofers idinga i-amplifier yangaphandle.Uma ukhetha ukusebenzisa i-subwoofer esebenzayo, uzodinga ukuthenga intambo ye-subwoofer, njengoba kuzodingeka uyixhume kumamukeli wesistimu yomsindo, njengoba kuchazwe ngenhla.

Uzoqaphela ukuthi ohlelweni lomsindo wetiyetha yasekhaya, i-subwoofer iyisipikha esikhulu kunazo zonke.Ingabe enkulu ingcono?Yebo!Uma isipikha se-subwoofer sikhulu, umsindo ujula.Izipikha ezinkulu kuphela ezingakhiqiza amathoni ajulile owazwa ku-subwoofer.

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

Ngaphansi kwefenisha.Uma ufuna ngempela ukuzwa ukudlidliza komsindo ojulile, ocebile wefilimu noma ukwakheka komculo, ukuyibeka ngaphansi kwefenisha yakho, njengosofa noma isitulo, kungathuthukisa leyo mizwa.

eduze kodonga.Beka eyakhoibhokisi le-subwoofereduze kodonga ukuze umsindo uphendule odongeni futhi ukhulise i-bass.

Indlela yokukhetha i-subwoofer engcono kakhulu

Ngokufanayo nezikhulumi ezijwayelekile, imininingwane ye-subwoofer ingathinta inqubo yokuthenga.Kuye ngokuthi yini oyifunayo, yilokhu okufanele ukubheke.

I-Frequency Range

Imvamisa ephansi kakhulu ye-subwoofer umsindo ophansi kakhulu umshayeli wesipikha angawukhiqiza.Ifrikhwensi ephezulu kakhulu umsindo ophakeme kakhulu umshayeli angawuthola.Ama-subwoofers angcono kakhulu akhiqiza umsindo wehle uze ufike ku-20 Hz, kodwa umuntu kufanele abheke ububanzi befrikhwensi ukuze abone ukuthi i-subwoofer ingena kanjani kusistimu ye-stereo iyonke.

Ukuzwela

Uma ubheka imininingwane yama-subwoofers adumile, bheka ukuzwela.Lokhu kubonisa ukuthi angakanani amandla adingekayo ukuze kukhiqizwe umsindo othile.Lapho ukuzwela kuphezulu, amandla amancane i-subwoofer idinga ukukhiqiza i-bass efanayo nesipikha sezinga elifanayo.

Uhlobo lweKhabhinethi

Ama-subwoofers avalelwe asevele akhelwe ebhokisini le-subwoofer avame ukukunikeza umsindo ojulile, ogcwele kuno ongavaliwe.Ikesi elinembobo lingcono kumisindo ephezulu, kodwa hhayi amathoni ajulile.

Impedance

Ukuphazamiseka, okukalwa ngama-ohms, kuhlobene nokumelana kwedivayisi nokwamanje ngomthombo womsindo.Ama-subwoofers amaningi ane-impedance engu-4 ohms, kodwa ungathola futhi ama-subwoofers angu-2 no-8 ohm.

Ikhoyili yezwi

Iningi lama-subwoofers liza nekhoyili yezwi elilodwa, kodwa abathanda umsindo abanolwazi lwangempela noma abanomdlandla bavame ukukhetha ama-dual voice subwoofers.Ngamakhoyili amabili ezwi, ungakwazi ukuxhuma isistimu yomsindo ngokubona kwakho kufaneleka.

Amandla

Uma ukhetha i-subwoofer engcono kakhulu, qiniseka ukuthi ubheka amandla alinganiselwe.Ku-subwoofer, amandla e-RMS akalwe abaluleke kakhulu kunamandla aphezulu akalwe.Lokhu kungenxa yokuthi ikala amandla aqhubekayo kunamandla aphezulu.Uma usuvele une-amplifier, qiniseka ukuthi i-subwoofer oyibhekile ingakwazi ukuphatha lokho kukhishwa kwamandla.
