I-Subwoofers ibaluleke kakhulu kumava asekhaya. Xa uhamba kwi-movie yeshashalazi, awumangalisi nje kuphela kwimifanekiso eboniswe kwisikrini, kodwa izandi ezijikelezayo. Yintoni eyenza ukuba, ngokwenene, isandi ovakalelwa ngokwenene; Ubunzulu obunzulu obukugubungelayo uze ufike ngqo emanzini.
Isithethi esikhethekileyo, esaziwa njenge-subwoofer, sijongene nala mava. I-subwoofer yenzelwe kuphela ukuvelisa ii-frequencies eziphantsi.
Subwoofers
I-subwoofers encinci ixhaswa ngumqhubi wangaphandle, ngendlela efanayo neyezinye izithethi kwindlela yakho. Ukubaluleka oku kubaluleke apha kukuba ekubeni i-bass exine ifuna amandla amaninzi ukuvelisa izandi ezisezantsi, i-amplifier okanye i-receiver yakho kufuneka ikwazi ukuvelisa amandla okwaneleyo ukugcina imiphumo ye-bass ngaphandle kwe-amp. Ingakanani amandla kuxhomekeke kwimfuno yesithethi kunye nobukhulu begumbi (kunye nokuba ungakanani ubuncwane ongasenza ngesisu!).
Subwoofers enePower
Ukuxazulula ingxaki yamandla anganeleyo okanye ezinye iimpawu ezingenakho kwi-receiver okanye i-amplifier, i-subwoofers ene-powered devices ziqulethe iziqu okanye i-unit amplifier apho iimpawu ze-amplifier kunye ne-subwoofer zihambelana ngokufanelekileyo.
Njengenzuzo yecala, zonke iimfuno ze-subwoofer ezixhaswa ngumbane ngumlinganiselo womgca ukusuka kumkeli. Eli lungiselelo lithatha amandla amaninzi ngaphandle kwe-amp / receiver kwaye ivumela i-amp / receiver ukuba isebenze phakathi kwendawo ephakathi kunye nee-tweeters ngokulula.
I-Front-Driving and Down-Firing Subwoofers
I-front-firing subwoofers isebenzisa isithethi siqhutywe ukuze sikhanyise isandi ukusuka kwicala okanye phambi kwe-subwoofer enclosure.
I-subwoofers yokutshisa phantsi iqeshe isithethi ephakanyisiwe ukwenzela ukuba idibene phantsi, ukuya kumgangatho.
Izibuko kunye neeRadio Radiators
Ezinye iifowuni ze-subwoofer nazo zisebenzisa i-port eyongezelelweyo, ekhupha umoya ophezulu, ukwandisa isisombululo esiphezulu kwindlela efanelekileyo ngakumbi kuneendawo zokuvalwa.
Olunye uhlobo lwe-enclosure lusetyenzisa i-Radiator Passive ngaphezu kwesi sithethi, endaweni yesipoti, ukwandisa ukusebenza kakuhle nokuchaneka. I-Radiators engapheliyo ingaba isithethi ngekhoyili yezwi esusiwe okanye isithwathwa seplati. Esikhundleni sokuzulazula ngokuthe ngqo kumqondiso womsindo ohanjiswe ngombane, i-radiator engahambelaniyo iphendula emoyeni eqhutywe ngumqhubi we-subwoofer osebenzayo. Ekubeni i-radiator engagqityiyo igqibezela isenzo somqhubi osebenzayo, inceda ukwandisa impendulo ephantsi kwe-subwoofer.
Crossovers
I-crossover yinkomfa ye-elektroniki eyenza zonke ii-frequencies phantsi kweengongoma ezithile kwi-subwoofer; zonke iifom apha ngasentla kwinqanaba liphinda ziphinde zenziwe izikhulumi eziphambili, iziko kunye neenxa zonke. Ngokuqhelekileyo, i-subwoofer enhle ine-"crossover" yama-100hz.
Kukho imfuno yalezo zikhulu zeprogram zesithethi ezi-3 ezi-12 kunye ne-15 "woofers. Izithethi ze-satellites ezincinci, ezilungiselelwe ukufikelela kuma-middle-and-high frequencies, zithatha indawo engaphantsi kwaye ngoku ziqhelekileyo kwiinkqubo ezininzi zasekhaya .
I-Deep Bass ayikho i-Directional
Ukongezelela, ekubeni iifrikansi ezinzulu ezizaliswe yi-subwoofers azikho izikhokelo (njengamavili aphantsi okanye ngaphantsi komda weentetho). Kunzima kakhulu kwiindlebe zethu ukuba sicacise ngokucacileyo isiqendu apho isandi siza khona. Yingakho sinokuqonda nje ukuba inyikima ibonakala ngathi iyasijikeleza, kunokuba ivela kwinqanaba elithile.
Ukufakwa kwee-Subwoofer
Njengomphumo wesandi esingenalathisi esenziwa kwakhona yi-subwoofer, inokufakwa kwenye indawo kwigumbi. Nangona kunjalo, iziphumo eziphezulu zixhomekeke kwisayizi sendawo, uhlobo lomgangatho, impahla kunye nokwakhiwa kwodonga. Ngokuqhelekileyo, ukubekwa ngokufanelekileyo kwi-subwoofer kukuphambi kwegumbi, ngakwesobunxele okanye ngasekunene kwezithethi eziphambili, okanye kwikona yangaphambili legumbi.
Kwakhona, abaninzi abamkeli bemidlalo yaseshashalazini banikezela ngemiphumo emibili ye-subwoofer- ebonisa ukulungelelanisa xa ufumanisa ukuba enye i-subwoofer ayikuboneleli iziphumo ozifunayo okanye ube negumbi elikhulu.
Wired okanye Wireless
Inombolo ekhulayo ye-subwoofers enikwe amandla inikezela ukuxhumeka kwentambo. Oku kwenza uninzi oluninzi njenge-powered subs zikwazi ukuzakhela izixhobo, kwaye ziphelisa imfuneko yecandelo lokuxhunywa elide phakathi kwe-subwoofer kunye nomkeli womdlalo womdlalo. I-subwoofer ene-wireless-enabled-enabled often comes with a kit of transmitter ezingenakunyulwa kwii-subwoofer iziphumo kwanoma yimuphi umkeli womdlalo womdlalo.
Umthumeli odibeneyo kwi-home receiver receiver udlulisela iimpawu zomsindo ophantsi kwi-subwoofer engena-wire, kwaye ke ummkeli owenziwe kwi-subwoofer avumele ukukhulisa ngaphakathi kwi-subwoofer ukugunyaza umqhubi wesithethi ukuvelisa isandi esisidingo esiphantsi.
Ngaphantsi
Nangona zonke iinkcukacha zobuchwephesha kunye neendlela zokwakha ze-subwoofers, uhlobo lwe-subwoofer oyikhethayo kwinkqubo yakho kuxhomekeka kwiimpawu zendawo kunye nezinto ozikhethayo. Xa uya kumthengisi, thabatha iDVD eyintandokazi kunye / okanye i-CD enolwazi oluninzi lwe-bass kwaye uphulaphule indlela izandi ezizandileyo ngayo nge-subwoofers ezahlukahlukeneyo.
