Nokuba udlala igubu elilodwa emotweni yakho, useka inkqubo yethiyetha yakho yasekhaya ukuze ubukele imuvi entsha yeAvengers, okanye ukwakha inkqubo ye-stereo yebhendi yakho, mhlawumbi ujonge ezo nzulu, i-bass enamanzi.Ukufumana esi sandi, udinga i-subwoofer.

I-subwoofer luhlobo lwesithethi esivelisa kwakhona i-bass njenge-bass kunye ne-sub-bass.I-subwoofer iya kuthatha isignali ye-audio ephantsi kwaye iguqule kwisandi esingenakukwazi ukuvelisa i-subwoofer.

Ukuba inkqubo yesithethi sakho imiselwe ngokuchanekileyo, unokufumana isandi esinzulu, esityebileyo.Isebenza njani i-subwoofer?zeziphi ezona subwoofer zingcono, kwaye ngaba ngokwenene zinempembelelo enkulu kwindlela yakho yesandi ngokubanzi?Nantsi into ekufuneka uyazi.

Yintoni nasubwoofer?

Ukuba une-subwoofer, kufuneka kubekho enye i-subwoofer, akunjalo?ichanekile.Uninzi lwee-woofers okanye izithethi eziqhelekileyo zinokuvelisa kuphela isandi ukuya kutsho malunga ne-50 Hz.I-subwoofer ivelisa isandi esisezantsi ukuya kuthi ga kwi-20 Hz.Yiyo loo nto igama elithi "subwoofer" lisuka kwintswahla ephantsi eyenziwa zizinja xa zikhonkotha.

Ngelixa umahluko phakathi kwe-50 Hz threshold yezithethi ezininzi kunye ne-subwoofer's 20 Hz threshold unokuvakala ungabalulekanga, iziphumo ziyabonakala.I-subwoofer ikuvumela ukuba uzive i-bass kwingoma kunye nefilimu, okanye nayiphi na enye into oyimameleyo.I-low frequency response ephantsi ye-subwoofer, inamandla kwaye i-juicy eninzi iya kuba yi-bass.

Kuba ezi toni ziphantsi kakhulu, abanye abantu abanako ukuva ii-bass ezivela kwi-subwoofer.Yiyo loo nto i-subwoofer yecandelo lokuziva ibaluleke kakhulu.

Iindlebe ezincinci, ezisempilweni zinokuva kuphela izandi ezisezantsi njenge-20 Hz, okuthetha ukuba iindlebe ezikwiminyaka ephakathi ngamanye amaxesha ziyasokola ukuva izandi ezinzulu kangako.Nge-subwoofer, uqinisekile ukuva ukungcangcazela nokuba awuyiva.

Isebenza njani i-subwoofer?

I-subwoofer idibanisa nezinye izithethi kwi-sound system epheleleyo.Ukuba udlala umculo ekhaya, mhlawumbi une-subwoofer eqhagamshelwe kumamkeli wakho womsindo.Xa umculo udlalwa ngezithethi, uthumela izandi ezisezantsi kwi-subwoofer ukuze zivelise kwakhona ngokufanelekileyo.

Xa kuziwa ekuqondeni indlela i-subwoofers esebenza ngayo, unokudibana nazo zombini iintlobo ezisebenzayo kunye ne-passive.I-subwoofer esebenzayo ine-amplifier eyakhelwe-ngaphakathi.I-Passive subwoofers ifuna iamplifier yangaphandle.Ukuba ukhetha ukusebenzisa i-subwoofer esebenzayo, kuya kufuneka uthenge ikhebula le-subwoofer, njengoko kuya kufuneka udibanise kwi-receiver ye-sound system, njengoko kuchazwe ngasentla.

Uyakuqaphela ukuba kwinkqubo yesandi yethiyetha yasekhaya, i-subwoofer sesona sithethi sikhulu.Ngaba inkulu ingcono?Ewe!Ubukhulu besithethi se-subwoofer, isandi esinzulu.Izithethi ze-bulkier kuphela ezinokuvelisa iithoni ezinzulu ozivayo kwi-subwoofer.

Kuthekani ngokungcangcazela?Isebenza kanjani lento?Ukusebenza kwe-subwoofer kuxhomekeke kakhulu kwindawo yayo.Iinjineli zeaudio eziqeqeshiweyo zincoma ukubeka ii-subwoofers:

Ngaphantsi kwefenitshala.Ukuba ufuna ngokwenene ukuva ukungcangcazela kwesandi esinzulu, esityebileyo semuvi okanye ukwakhiwa komculo, ukuyibeka phantsi kwefenitshala yakho, njengesofa okanye isitulo, kunokuphucula ezo mvakalelo.

ecaleni kodonga.Beka eyakhoibhokisi ye-subwooferecaleni kodonga ukuze isandi sibuyele eludongeni kwaye sinyuse i-bass.

Indlela yokukhetha eyona subwoofer engcono

Ngokufana nezithethi eziqhelekileyo, i-specs ye-subwoofer inokuchaphazela inkqubo yokuthenga.Kuxhomekeke kwinto oyilandelayo, le yinto omawuyijonge.

Uluhlu lokuphindaphinda

I-frequency ephantsi ye-subwoofer sesona sandi siphantsi umqhubi wesithethi anokuvelisa.Esona sandi siphezulu sesona sandi sinokufunyanwa ngumqhubi.Ii-subwoofers ezilungileyo kakhulu zivelisa isandi ukuya kwi-20 Hz, kodwa umntu kufuneka ajonge uluhlu lwamaza ukuze abone ukuba i-subwoofer ingena njani kwisistim iyonke.

Uvakalelo

Xa ujonge ii-specs ze-subwoofers ezithandwayo, jonga uvakalelo.Oku kubonisa ukuba angakanani amandla afunekayo ukuvelisa isandi esithile.Ukuphakama kovakalelo, amandla amancinci i-subwoofer idinga ukuvelisa i-bass efanayo njengesithethi esikwizinga elifanayo.

Uhlobo lweKhabhinethi

I-subwoofers evalelweyo esele yakhiwe kwibhokisi ye-subwoofer idla ngokukunika isandi esinzulu, esipheleleyo kuneso singavalwanga.Icasi enemingxuma ingcono kwizandi ezingxolayo, kodwa hayi ithowuni ezinzulu.

Impedance

I-impedance, ilinganiswe kwii-ohms, inxulumene nokuchasana kwesixhobo ukuya okwangoku ngomthombo womsindo.Uninzi lwee-subwoofers zine-impedance ye-4 ohms, kodwa ungafumana i-2 ohm kunye ne-8 ohm subwoofers.

Ikhoyili yelizwi

Uninzi lwee-subwoofers ziza nekhoyili yelizwi elinye, kodwa abathandi bomsindo abanamava ngokwenyani bahlala bekhetha ii-coil subwoofers zelizwi ezimbini.Ngeekhoyili zelizwi ezimbini, unokudibanisa inkqubo yesandi njengoko ubona kufanelekile.

Amandla

Xa ukhetha i-subwoofer engcono kakhulu, qiniseka ukuba ujonge ukulinganiswa kwamandla.Kwi-subwoofer, ukulinganiswa kwamandla e-RMS kubaluleke kakhulu kunamandla aphezulu.Oku kungenxa yokuba ilinganisa amandla aqhubekayo endaweni yamandla aphezulu.Ukuba sele unesandisi-lizwi, qiniseka ukuba i-subwoofer oyijongileyo inokusingatha loo mveliso yamandla.
