Xa kuziwa ekuhlanganiseni iprogram enkulu yemidlalo yasesekhaya, i- subwoofer iyimfuneko yokuthenga . I-subwoofer isithethi esikhethekileyo esilungiselelwe ukuvelisa amaqondo aphantsi kakhulu. Ngomculo, oko kuthetha ukuba isiseko sombane okanye umbane, kunye nezinye iifrimu ezithetha ukugqithwa kwesitimela egijima phantsi kweendlela zomzila weetroliwe, umlilo kunye nokuqhuma, kunye novavanyo olukhulu: ukugqithisa okukhulu kwenyikima.
Nangona kunjalo, ngaphambi kokuba unandipha yonke into, kufuneka udibanise i-subwoofer kunye nenkqubo yakho yonke, kunye nendlela odibanisa ngayo i-subwoofer kuyo yonke indawo yokusekwa kwetater yakho kuxhomekeke ekubeni ingaba i-Passive okanye i-Powered.
Subwoofers
I-subwoofers encinci ibizwa ngokuthi "i-passive" kuba ifuna ukuxhaswa yi-amplifier yangaphandle, ngendlela efanayo neenkulumo zemveli. Okubalulekileyo oku kuthethwa apha kukuba ekubeni i-subwoofers idinga amandla amaninzi ukuvelisa izandi ezisezantsi ezivakalayo, i-amplifier okanye i-receiver yakho kufuneka ikwazi ukuvelisa amandla okwaneleyo ukugcina iziphumo ze-bass ezikhutshwe yi-subwoofer ngaphandle kokukhipha ukunikezelwa kwamandla kwi-receiver yakho okanye kwisikhululi. Ingakanani amandla kuxhomekeke kwimimiselo yesithethi se-subwoofer kunye nobukhulu begumbi (kunye nokuba ungaphantsi kwesisu, okanye uninzi kangakanani ufuna ukuphazamisa abamelwane!).
Njengoko zonke ezinye iiproseshi ezifakwe kwi-home-based home theater, udibanisa ucingo lwesithethi kwi-amplifier kwi-subwoofer engaphantsi. Ngokufanelekileyo, kufuneka uqale uqhagamshele umgca we-subwoofer umphumo we-home receiver receiver okanye ipropressor ye-AV yepropressor , ukuya kumgca we-line-subwoofer amplifier-uze udibanise i-subwoofer engenzileyo kwii-terminals zesikhulumi ezinikezelwe kwi-amplifier ye-subwoofer.
Omnye umzekelo we-Passive Subwoofer yi-OSD Audio IWS-88 In-Wall Subwoofer.
Omnye umzekelo we-amplifier yangaphandle efunekayo xa usebenzisa i-Passive Subwoofer yi-Dayton Audio SA230.
I-subwoofers encinci isetyenziswe ngokubanzi kwizifakelo zenkcubeko apho i-subwoofer ingafakwa eludongeni, nangona kukho i-subwoofers engokomveli yendalo eyenziwa yinto ekhoyo. Kwakhona, ezinye iinkqubo ezingabonakaliyo kwikhaya-in-in-box-box systems ziquka i-subwoofer engekho, njenge- Onkyo HT-S3800 .
Subwoofers enePower
Ukuxazulula ingxaki yamandla anganeleyo okanye ezinye iimpawu ezinxulumene nazo ezingabikhoyo kumkeli okanye amplifier, i-Powered Subwoofers (ekwabizwa ngokuba yi-Active Subwoofers esebenzayo) iyasetyenziswa. Olu hlobo lwe-subwoofer luyi-speaker-content / amplifier yokucwangcisa apho iimpawu ze-amplifier kunye ne-subwoofer zihambelana ngokufanelekileyo kwaye zombini zifakwe kwi-enclosure efanayo.
Njengenzuzo yecala, zonke iimfuno ze-subwoofer ezixhasayo zixhamlwano olulodwa lwekhebula ukusuka kumncedisi wekhamera yomzi okanye kwiprojekti ye-preamp / umqhubi womgca-projekthi (ekwabizwa ngokuba yi-prewoofer preamp output okanye i-LFE output). Eli lungiselelo lithatha umthwalo omkhulu umthwalo kude nommkeli kwaye uvumela ukuba izikhulumi zabo zikwazi ukulawula amandla phakathi kwebala kunye neentetho ze-tweeter ngokulula.
Omnye umzekelo we-Powered Subwoofer yi- Fluance DB150 .
Yiyiphi engcono - i-Passive okanye i-Powered?
Zonke ezinye izinto zilingana, nokuba i-subwoofer ayifuni okanye inikwe amandla akuyiyo into ecacileyo malunga nokuhle kwe-subwoofer. Nangona kunjalo, i-subwoofers ene-Powered yeyona nto isetyenziswa ngokuqhelekileyo njengokuba i-amplifiers eyakhelwe ngaphakathi kwaye ayixhomekeke kuyo nayiphina imilinganiselo ye-amplifier yomnye umkeli okanye amplifier. Oku kwenza kube lula kakhulu ukusebenzisa kunye nabamkeli bemidlalo yasesekhaya namhlanje. Zonke izamukeli zasekhaya zesevisi ziza zixhotyiswe ngenye enye okanye amabini angaphantsi kwee-subwoofer iziphumo zangaphambili ze-amp-oop ezenzelwe ukuxhuma kwi-subwoofer enegunya.
Ngakolunye uhlangothi, oko kufuneka uyenze ukuze usebenzise i-subwoofer engaphantsi yintengo yokuthenga i-subwoofer amplifier, leyo, kwiimeko ezininzi kunokubiza ngaphezu kwe-subwoofer engenayo.
Ngamanye amazwi, kwiimeko ezininzi, kuya kuba yindleko ephezulu ukuthenga kuphela i-subwoofer enegunya elinamandla endaweni ye-Subwoofer engekho. Ukuba ukhetha olu khetho i-subwoofer eyaphuma kwi-Home Receiver Receiver yayiza kudibanisa nomgca-mpahla wesikhombisi-mpahla yangaphandle-ekunxibelelaneni, kunye nomnxibelelwano we-subwoofer yesithethi esingaphandle kwintetho kwisitishi se-subwoofer.
Enye enye inketho yokuxhumeka yinto ekhoyo kwi-subwoofer engaphantsi yinto yokuba ukuba i-subwoofer engenazo i-interwoofer engenawo kwaye ifanelwe ukuxhumeka kweesithethi eziqhelekileyo, unokudibanisa uxhulumaniso lwesithethi sokunxele kunye ne-right on receiver okanye amplifier kwi-subwoofer engaphantsi uze udibane nekhohlo kunye nesistim sokunxibelelana kwesistim esifanelekileyo kwi-subwoofer engekho phantsi kwiisithethi zakho zangasese zangasese nakwesokudla (bona isithombe).
Kwenzeka ntoni kule ndlela yokuseta ukuba i-subwoofer "iya kucima" ii-frequencies ezisezantsi isebenzisa i-crossover yangaphakathi, ethumela umgama ophakathi phakathi kunye nezikhundla eziphezulu kwizivakalisi ezongezelelweyo ezixhunyiwe kwiziphumo zesithethi se-subwoofer.
Olu hlobo lokuseta luya kuphelisa imfuneko yokuphucula ngaphandle kwe-amplifier yangaphandle nje nge-subwoofer engenziwanga, kodwa ingafaka ingxaki eninzi kwi-receiver yakho okanye kwisikhululi-mpahla ngenxa yeemfuno ze-output frequency sound output.
Umyinge ukuya kwi-Subwoofer Imigaqo yokuXhuma
Kwakhona kubalulekile ukuba uqaphele ukuba amaninzi amanqaku angaphantsi ayenazo zombini izalathiso zenkalo kunye nekhonkco zokudibanisa. Ukuba kunjalo, i-subwoofer yi-Powered Subwoofer. Nangona kunjalo, kule mzekelo, yi-subwoofer engayamkela iimpawu ukusuka kwisixhumano sesithethi se-amplifier okanye umkhulisi / i-home receiver receiver.
Oku kuthetha ukuba ukuba unomkeli wekhenikhi endala okanye i-amplifier engenawo uxhumano olusisiseko lwe-subwoofer uxhumano lwe-preamp, ungasasebenzisa i-subwoofer enikwe amandla, ukuba inikeza uxhulumaniso lweesithethi eziqhelekileyo ngaphezu kokufakelwa komgca. Kudinga umonde kodwa ke akunzima ukuxhuma .
Option Wire Connection Option
Kwakhona, enye inketho yokuxhumela i-subwoofer eyaziwayo kakhulu (isebenza kuphela kunye ne-subwoofers enegunya) yintambo engenazintambo phakathi kwe-subwoofer kunye ne-receiver home or amplifier. Oku kungaqaliswa ngeendlela ezimbini.
Enye indlela xa i-subwoofer iza kunye nommkeli womnxeba ongenamakhangelo kwaye unika umthumeli wangaphandle ongenawo ucingo okhupha umgca we-subwoofer umgca we-home or receiver.
Omnye umzekelo we-Wireless Subwoofer yiMonoprice 110544 enokuthengwa kakhulu kwi-inch 110-watt model.
Inketho yesibini kukuthenga itikethi yokunxibelelana / yokufumana i-wireless engenanto engakwazi ukudibanisa kunoma iyiphi i-subwoofer enegunya elinomgca welayini kunye nayiphi na i-receiver receptor, ipro AV, okanye i-amplifier ene-subwoofer okanye i-LFE.
Omnye umzekelo weTystem Subwoofer Transmitter / Receiver kit yi-Sunfire Wireless Subwoofer Connection Kit.
Gqibela Thatha
Xa uthengisa i-subwoofer ukuyisebenzisa kunye nendawo yakho yaseshashalazini, khangela ukuba i-home theater yakho, AV, okanye i-receiver sound sound is output (preame Out, Out Out, okanye LFE Out). Ukuba kunjalo, ngoko kufuneka usebenzise i-subwoofer enegunya.
Kwakhona, ukuba uthengele i-receiver entsha yeshashalazi yasekhaya, kwaye ube ne-subwoofer ekhohlo ekhohlo eyayiqala nge-home-in-a-box system, khangela ukuba ngaba i-subwoofer ingumgcini we-subwoofer. Ukunikezelwa kukuba akunalo i-subwoofer yenkcazo yegalelo kwaye inxibelelwano yesithethi kuphela.
Ukuba ngaba kunjalo, kuya kufuneka uzuze umbane wongeziweyo ukuze ugunyaze i-subwoofer, okanye, ukuba i-subwoofer inomxholo wesistim kunye nesistim sekhonkco, ungakwazi ukudibanisa i-subwoofer kwiziphumo eziphambili zesithethi esisekhohlo / sokunene. womntu owamkelayo uze udibanise izithethi zakho zangasese ezisekhohlo kunye nezilungele kwisiphumo soxhumo lwe-subwoofer.
Kusuka kwi-home-inater-in-bhokisi engabizi ukuya kwiiprogram eziphezulu eziqhelekileyo ezifakiwe, i-subwoofer iyadingeka ukubonelela ngee-frequencies eziphantsi.
