Cov teebmeem ntawm cov kab lus hais lus ntawm kev hais lus tuaj yeem ntsuas tau thiab tuaj yeem qhia tau tias hloov cov kab hais lus tuaj yeem muaj qhov cuam tshuam rau lub suab ntawm lub kaw lus.
Siv ntsuas los daws qhov teeb meem Cable
Ib tus qauv sim qauv siv Clio 10 FW audio analyzer thiab MIC-01 ntsuas microphone los ntsuas cov lus teb ntawm Revel Performa3 F206 hais lus hauv chav. Kev ntsuas hauv chav yuav tsum tau ua kom paub tseeb tias tsis muaj suab nrov ib puag ncig. Yog, qhov ntsuas hauv chav qhia tau hais tias muaj ntau qhov cuam tshuam ntawm chav tsev acoustics, tab sis qhov ntawd tsis muaj teeb meem vim tias ntawm no, txij li peb tab tom nrhiav tsuas yog qhov sib txawv ntawm qhov ntsuas ntsuas thaum peb hloov cov cables.
Thiab, tsuas yog txhawm rau rov sau cov kev xav hauv qab no: Tus neeg hais lus tus tsav tsheb thiab cov khoom sib txuas ua ke ua lub lim hluav taws xob nyuaj uas tau kho kom tus neeg hais lus lub suab xav tau. Ntxiv kev tiv thaiv, nyob rau hauv daim ntawv ntawm ib tug ntau resistive hais lus cable, yuav hloov lub frequencies ntawm lub lim ua hauj lwm thiab yog li hloov lub zaus teb ntawm tus hais lus. Yog hais tias lub cable ntxiv ho ntau inductance los yog capacitance rau lub lim, ces qhov ntawd, ib yam nkaus, tuaj yeem cuam tshuam lub suab.
Test 1: AudioQuest vs. QED vs. 12-Gauge
Nyob rau hauv cov kev ntsuam xyuas no, peb ntsuas qhov cuam tshuam ntawm qhov sib txawv high-end cables nyob rau hauv 10- mus rau 12-foot lengths thiab muab piv rau qhov ntsuas nrog generic 12-gauge speaker cable. Vim tias qhov ntsuas tau nyob rau hauv feem ntau zoo sib xws, peb mam li nthuav tawm lawv ntawm no peb zaug ib zaug, nrog ob lub high-end cables vs. generic cable.
Daim ntawv qhia ntawm no qhia cov kab hluav taws xob dav dav (xiav kab), AudioQuest Hom 4 cable (liab kab) thiab QED Nyiaj Ib Xyoo (ntsuab kab). Raws li koj tuaj yeem pom, feem ntau qhov sib txawv yog qhov me me. Qhov tseeb, feem ntau qhov sib txawv yog nyob rau hauv qhov qub, me me ntsuas-rau-kev ntsuas qhov sib txawv koj tau txais thaum ua kev ntsuas ntawm lub suab transducers vim muaj cov suab nrov, thermal fluctuations hauv cov tsav tsheb, thiab lwm yam.
Muaj qhov sib txawv me me hauv qab 35 Hz; cov kab hluav taws xob siab tshaj plaws tau tsim cov suab bass thaj tsam tsawg dua los ntawm tus hais lus hauv qab 35 Hz, txawm hais tias qhov sib txawv ntawm qhov kev txiav txim ntawm -0.2 dB. Nws tsis zoo li qhov no yuav hnov, vim lub pob ntseg tus txheeb ze insensitivity nyob rau hauv no ntau yam; rau qhov tseeb hais tias feem ntau cov suab paj nruag tsis muaj ntau cov ntsiab lus nyob rau hauv no ntau yam (rau kev sib piv, tus nqi qis tshaj ntawm tus qauv bass guitars thiab upright basses yog 41 Hz); thiab vim tias tsuas yog cov neeg hais lus loj loj muaj ntau qhov tso zis hauv qab 30 Hz. (Yog lawm, koj tuaj yeem ntxiv lub subwoofer mus rau qhov qis, tab sis yuav luag tag nrho cov ntawm nws tus kheej-powered thiab yog li yuav tsis cuam tshuam los ntawm tus hais lus cable.) ko taw nyob rau hauv txhua txoj kev.
Peb tsis tau muaj sijhawm los ntsuas cov khoom hluav taws xob ntawm AudioQuest cable (tus txiv leej tub xav tau nws rov qab los sai sai), tab sis peb tau ntsuas qhov kev tiv thaiv thiab kev muaj peev xwm ntawm QED thiab generic cables. (Qhov inductance ntawm cov cables qis dhau rau kuv Clio 10 FW ntsuas.)
Generic 12-gauge
Resistance: 0.0057 Ω per ft. Capacitance: 0.023 nF ib ko taw
QED Nyiaj Ib Xyoo
Resistance: 0.0085 Ω ib ft. Capacitance: 0.014 nF ib ko taw
Test 2: Shunyata vs. High-End Prototype vs. 12-Gauge
Qhov kev sib tw tom ntej no tau coj tawm ntau dua-kawg cable: 1.25-nti-thick Shunyata Tshawb Fawb Etron Anaconda thiab 0.88-nti-tuab qauv kab uas tau tsim los rau lub tuam txhab suab nrov. Ob leeg pom thicker vim tias lawv siv woven tubing los npog cov xov hlau sab hauv, tab sis tseem, lawv ob leeg hnyav thiab kim. Shunyata Reserach cable mus txog $ 5,000 / khub.
Daim ntawv qhia ntawm no qhia cov kab hluav taws xob dav dav (xiav kab), Shunyata Tshawb Fawb cable (liab kab) thiab cov tsis muaj npe qauv high-end cable (ntsuab kab). Nov yog qhov ntsuas hluav taws xob:
Shunyata Kev Tshawb Fawb Etron Anaconda
Resistance: 0.0020 Ω ib ft. Capacitance: 0.020 nF ib ko taw
High-End Prototype
Resistance: 0.0031 Ω per ft. Capacitance: 0.038 nF ib ko taw
Ntawm no peb pib pom qee qhov sib txawv, tshwj xeeb tshaj yog hais txog 2 kHz. Mus zoom rau qhov ze dua…
Test 2: Zoom View
Los ntawm kev nthuav dav qhov loj me (dB) thiab txwv qhov bandwidth, peb tuaj yeem pom tias cov kab loj loj no ua rau muaj qhov sib txawv ntawm tus neeg hais lus teb. F206 yog 8-ohm hais lus; Qhov loj ntawm qhov sib txawv no yuav nce nrog 4-ohm hais lus.
Nws tsis yog qhov sib txawv ntau - feem ntau yog qhov nce ntawm +0.20 dB nrog Shunyata, +0.19 dB nrog tus qauv - tab sis nws npog ntau tshaj peb octaves. Nrog tus hais lus 4-ohm, cov duab yuav tsum yog ob npaug, yog li +0.40 dB rau Shunyata, +0.38 dB rau tus qauv.
Raws li kev tshawb fawb tau hais hauv thawj tsab xov xwm, low-Q (high bandwidth) resonances ntawm 0.3 dB magnitude tuaj yeem hnov. Yog li los ntawm kev hloov los ntawm cov kab hluav taws xob sib txuas lossis ib qho me me-gauge high-end cable mus rau ib qho ntawm cov cables loj, nws yog kiag li, qhov tseeb tau hais tias qhov sib txawv yuav hnov.
Qhov txawv ntawd txhais li cas? Qhov ntawd nyob ntawm tus kheej. Tej zaum koj yuav tsis pom nws, thiab nws yuav maj mam hais qhov tsawg kawg nkaus. Peb tsis tuaj yeem kwv yees seb nws puas yuav txhim kho lossis txo qis lub suab ntawm tus neeg hais lus; nws yuav txhawb nqa lub treble, thiab nrog qee tus neeg hais lus uas yuav zoo thiab lwm tus nws yuav phem. Nco ntsoov tias kev kho lub suab nrov hauv chav tsev yuav muaj qhov ntsuas loj dua.
Test 3: Theem Ua Haujlwm
Tshaj tawm ntawm kev xav paub tiag tiag, peb kuj tau ua qhov sib piv ntawm qib ntawm theem hloov pauv los ntawm cov kab hluav taws xob, nrog rau cov kab hluav taws xob hauv xiav, Audioquest hauv liab, tus qauv hauv ntsuab, QED hauv txiv kab ntxwv thiab Shunyata hauv ntshav. Raws li koj tuaj yeem pom saum toj no, tsis muaj qhov pom tau hloov pauv tshwj tsis yog ntawm cov zaus tsawg heev. Peb pib pom cov teebmeem hauv qab 40 Hz, thiab lawv tau pom ntau dua nyob ib puag ncig 20 Hz.
Raws li tau sau tseg ua ntej, cov teebmeem no tej zaum yuav tsis hnov zoo rau cov neeg feem coob, vim hais tias feem ntau cov suab paj nruag tsis muaj ntau cov ntsiab lus ntawm qhov tsawg zaus, thiab cov neeg hais lus feem ntau tsis muaj qhov tso zis ntau ntawm 30 Hz.. Txawm li cas los xij, peb tsis tuaj yeem hais meej tias cov teebmeem no yuav hnov zoo.
Yog li cov hais lus Cables ua qhov txawv?
Qhov kev sim no qhia tau tias cov neeg uas hais kom koj tsis tuaj yeem hnov qhov sib txawv ntawm ob tus neeg hais lus sib txawv ntawm qhov ntsuas qhov tsim nyog tsis raug. Nws tuaj yeem hnov qhov sib txawv los ntawm kev hloov cov cables.
Tam sim no, qhov txawv ntawd txhais li cas rau koj? Nws yuav twv yuav raug hu hloov maj mam. Raws li qhov muag tsis pom kev sib piv ntawm cov kab lus dav dav peb tau ua ntawm Lub Wirecutter tau pom, txawm tias cov neeg mloog tuaj yeem hnov qhov txawv ntawm cov cables, qhov kev ntshaw ntawm qhov sib txawv yuav hloov pauv nyob ntawm tus neeg hais lus koj siv.
Los ntawm cov kev xeem txwv tsis pub lees paub, nws zoo li qhov sib txawv loj hauv kev hais lus cable kev ua tau zoo yog vim feem ntau ntawm qhov kev tiv thaiv hauv cable. Qhov sib txawv loj tshaj plaws yog ntsuas nrog ob lub cables uas muaj qhov tsis kam qis dua li lwm tus.
Yog li, cov kab hais lus tuaj yeem hloov lub suab ntawm lub kaw lus. Tsis yog los ntawm ntau. Tab sis lawv yeej hloov tau lub suab.
