Nws puas yog ib tug ntse heev?
Kuv tau nco txog qhov kev nyuab siab npaum li cas los ua kom ntxiv ib subwoofer rau lub tso suab. Kuv hnov Revel Performa3 hais lus system, thiab nws nrog cov B110 subwoofer - ib qho ntawm ob peb subs kuv tau pom uas muaj qhov kho kom haum, ua qhov crossover cais tawm qhov qis frequencies rau lub sub thiab lim qhov tob bass ntawm lub ntsiab lus tseem ceeb.
Txhua tus A / V receiver nyob rau hauv lub khw muaj ib qho kev tsim kho hauv subwoofer crossover, thiab feem ntau lawv cia koj kho qhov taw qhia crossover - xws li, cov zaus hauv qab uas suab xa mus rau subwoofer, thiab saum toj no uas xa mus rau lub ntsiab hais lus. Tab sis kuv tuaj yeem xav txog ob peb lub suab paj nruag, kev siv amps thiab preamps uas muaj qhov sib tw ua ke.
Tau kawg, yuav luag txhua txhua qhov chaw subwoofer muaj ib qho kev ua crossover, tiam sis feem ntau ntawm lawv tsuas lim cov nruab nrab thiab cov treble tawm ntawm subwoofer. Ob peb lim cov ntses bass thaj tsam ntawm koj lub ntsiab lus, tab sis feem ntau ntawm qee zaus.
Yog li cas qhov teeb meem? Qhov tshij, qhov chaw sib crossover tsau yog feem ntau 80 Hz. Qhov ntawd ua haujlwm loj nrog cov ntsiab lus loj, tab sis nws yuav xa ntau dhau bass thaj tsam me me, ua rau lawv pauv thiab tejzaum nws ua puas lossis hnav tsis tau tawm ntxov. Yog hais tias qhov crossover taw siab dua, hais 120 Hz, uas yuav cawm tau cov neeg hais lus me me tab sis nws yuav tawm ntawm qhov "sonic hole" ntawm tus sub thiab lub ntsiab lus. Los sis nws yuav ua rau ntau lub suab sab tawm ntawm subwoofer, uas yuav ua rau txhua tus neeg pib suab zoo li Barry White.
Zuj zus yog tias subwoofer tsis muaj txoj kev los lim cov neeg tsawg tsawg zaus hauv cov ntsiab lus - uas cov ntsiab lus tham yuav ntshe ntxig ntawm ntau dhau bass thaj tsam. Zoo li cov hais mav los ntawm lawv txoj kev tsheb sib tw ua suab nrov heev.
Los ntawm kev teeb tsa kev tsim teeb meem koj tuaj yeem khiav ntawm lub PC, Revel B110's crossover yuav raug teem rau txhua zaus koj xav tau. (Koj tuaj yeem pom B110 tus txheej txheem ntawm tus yees duab saum toj no.) Cov downside tsuas yog tias koj yuav tsum khiav ntawm kev sib txuas ntawm kab ua ntej koj mus rau subwoofer thiab rov qab rau koj tus amp. Yog tias koj tsis muaj ib qho preamp thiab amp, koj yuav tsum tau txais ib tus neeg txais khoom los yog kev amp nrog preamp tawm / hwjchim amp hauv qab ntaw.
Lwm ntes yog cov B110 yog kim.
Yog vim li cas, thaum lub suab kev lag luam packs khaub ncaws cov npe ntawm cov lej siab tshaj plaws hauv cov nqi pheej yig xws li Sony STR-DH830 , nws tsis tsim ib qho yooj yim adjustable subwoofer crossover rau hauv ib lub tso suab tso nkag lossis cov amp los yog pheej yig subwoofer? Kuv tseem tsis tau paub nws tawm.
Koj puas siv lub subwoofer nrog koj lub tso suab? Yog li, puas yog koj nqes nws? Qhia rau peb paub hauv cov lus hauv qab no.
