Ib tus neeg hais lus tshwj xeeb, hu ua subwoofer, yog lub luag hauj lwm rau qhov kev sib tw sib sib zog nqus. Tus subwoofer no yog tsim los muab tsim tawm cov qis tshaj ntawm cov suab nrov. Hauv kev ua yeeb yam hauv tsev , qhov no feem ntau hu ua LFE (Tsawg Zog Los Sib Tham.
Qhov chaw suab cua uas sib txuas rau subwoofer raug xa mus rau raws li lub .1 channel .
Nrog cov koob npe ntawm tsev ua yeeb yam suab paj nruag los ua rau cov neeg hais lus tshwj xeeb rau kev sib txuas lus hauv nruab nrab, cov suab loj loj, ib puag ncig, thiab qee zaum qhov siab, qhov kev xav tau rau ib tus neeg hais lus me me xwb qhov ntawm cov yeeb yaj kiab ntawm cov yeeb yaj kiab yog qhov tseem ceeb dua. Txawm hais tias cov subwoofers tsis zoo li "thunderous" raws li cov subwoofers ua haujlwm nyob rau hauv qhov chaw ua yeeb yam hauv zos, cov lus nrov tshwj xeeb no tseem tuaj yeem tsoo lub tsev los yog ua rau cov neeg nyob hauv cov tsev nyob hauv koj lub tsev los yog lub rooj sib dhos tsis haum.
Kev yuav ib subwoofer yog ib qho tseem ceeb thaum nws los txog rau kev ua yeeb yam hauv tsev.
Hom ntawm Subwoofers
Passive Subwoofers
Passive subwoofers yog powered los ntawm ib tus neeg sab nrauv, ua tib yam li lwm tus tham hauv koj lub cev. Qhov tseem ceeb ntawm no yog vim tias cov ntses bass thaj tsam yuav tsum muaj ntau lub zog los ua kom muaj suab nrov tsawg zaus, koj tus ntivtawm lossis tus tau txais kev pab yuav tsum muaj peev xwm tso tawm kom muaj peev xwm ua kom tau txais qhov teebmeem bass thaj tsam hauv cov subwoofer uas tsis tau poob ntawm lub amp. Ntau npaum li cas muaj hwj chim nyob ntawm cov kev cai ntawm tus neeg hais lus thiab qhov loj ntawm chav tsev (thiab ntau npaum li cas koj yuav mob plab!).
Powered Subwoofers
Yuav kom daws tau qhov teeb meem ntawm lub hwj chim tsis zoo los yog lwm yam ntxwv uas tsis muaj peev xwm nyob rau hauv ib lub receiver los yog amplifier, powered subwoofers yog tus kheej hais lus / amplifier configurations hauv tib lub txee, qhov twg cov yam ntxwv ntawm kev hloov zog thiab subwoofer zoo sib npaug.
Ua ib qho txiaj ntsim zoo rau kev sib txuas lus nrog tus neeg hais lus thiab tus neeg hais ua haujlwm nyob hauv tib lub txee, txhua tus xav tau kev subwoofer xav tau yog cov kab tawm ntawm lub tsev ua yeeb yam hauv tsev. Qhov kev hloov no yuav siv ntau lub hwjchim ntawm lub amp / receiver ntau thiab pub rau amp / receiver fais fab ntawm mid-range thiab tweeters ntau yooj yim.
Yog xav paub ntxiv txog qhov sib txawv thiab yuav ua li cas txhawm rau kev xeem Passive and Powered Subwoofers, nyeem kuv cov ntawv ntxiv: Passive Subwoofers vs Powered Subwoofers .
Cov Yam Ntxwv Ntxiv Subwoofer
Ntxiv subwoofer tsim variations yog ua haujlwm rau ntxiv optimize npaum li cas kev ua tau zoo. Cov kev hloov no muaj xws li siv Kev Tiv Thaiv Cov Ntej thiab Hluav Taws Xob Yeej , nrog rau kev siv, qee zaus, Cov Nruab Nrab lossis Cov Teeb Tseem Cuam Tshaj Tawm .
Pem hauv ntej muab cov ntaub ntawv hauv qab ntiag tug tso rau ib tus neeg hais lus kom paub tias nws tawm suab los ntawm sab nrauv los sis pem hauv ntej ntawm subwoofer enclosure. Cov ntaub ntawv nram qab no muab cov lus qhia uas tau muab tso rau hauv kom ntws tawm mus rau hauv av. Ntxiv ntawd, qee qhov chaw nkaum tau ntiav ib qho chaw nres nkoj, ntxiv zog rau cov cua, nce bass teb ntau dua li cov ntaub thaiv khoob khoob. Hom kev tsim no yog hu ua Bass Reflex.
Lwm hom ntawv thaiv kev siv tus Radiator Passive ntxiv nrog rau tus neeg hais lus, siv qhov chaw nres nkoj, los nce kev ua haujlwm thiab qhov tseeb. Passive radiators tuaj yeem yog cov neeg tham nrog lub suab tawm raug tshem tawm, lossis lub rooj sib txuas ncaj nraim.
Crossovers
Feem ntau, ib tus zoo subwoofer muaj "crossover" zaus txog 100hz. Tus ntoo khaub lig yog ib qho hluav taws xob hauv hluav taws xob uas yog cov kev taw rau cov qeeb hauv qab uas taw rau lub subwoofer; tag nrho cov frequencies saum toj no uas taw tes yog tswv cuab lub ntsiab, qhov chaw, thiab ib puag ncig cov neeg hais lus. Plooj zuj zus yog qhov kev xav tau rau cov neeg hais lus 3-txoj kev nrog 12 "los yog 15" woofers. Cov suab lus me zog me me, kev kho kom zoo rau nruab nrab-thiab-high frequencies, coj mus rau qhov chaw tsis tshua muaj ntau thiab tam sim no muaj ntau nyob rau hauv ntau lub tsev ua yeeb yam hauv tsev.
Directionality
Tsis tas li ntawd xwb, vim cov laj thawj sib sib zog nqus ntau dua los ntawm cov subwoofers yog cov uas tsis yog directional (raws li qhov tsis sib xws uas nyob ntawm lossis qis dua qhov kev sib hais ntawm lub rooj sib hais). Nws yog qhov nyuaj heev rau peb lub pob ntseg ua tau pin-point taw tes rau cov kev taw qhia uas cov hom suab tuaj. Qhov no yog vim li cas peb thiaj tsuas paub tias muaj av qeeg zoo li txhua yam nyob ib ncig ntawm peb, tsis yog los ntawm kev coj ua.
Raws li ib qho kev txiav txim siab ntawm txhua tus neeg los yog cov tsis muaj kev coj ua ntawm lub suab tsis tshua muaj siab, lub subwoofer muab tso rau qhov chaw hauv chav. Txawm li cas los xij, qhov zoo tshaj plaws yog nyob ntawm seb qhov loj me, hom pem teb, khoom vaj khoom tsev, thiab kev siv phab ntsa.
