Vim li cas tus tsav tsheb 4Ω hlawv lub Tweeter thaum ua ke nrog 8Ω Amplifier?
Nov yog qhov tseeb tsis txaus siab:thaum tus tsav tsheb 4Ω txuas nrog 8Ω- ntsuas lub suab tso tawm, qhov tam sim no kos ob npaug. Ntau tus kws tshaj lij hais lus xaiv 4Ω cov neeg tsav tsheb xav tias "amplifier rated 8Ω txaus", thiab qhov tshwm sim yog kev tiv thaiv amplifier, lossis thaum mob hnyav, tweeter hlawv- tawm.
Vim li cas qhov no tshwm sim nrog sab nraud - cov tsav tsheb hlau nplaum hauv cov ntawv thov theem? Lub Φ135mm sab nrauv- cov neeg tsav tsheb hlau nplaum muaj qhov sib nqus flux ntau dua li sab hauv- hlau nplaum tsim, ua tiav 88 ± 3dB rhiab heev (ib txwm rau W-chav kawm tsav tsheb). Txawm li cas los xij, qhov nkhaus impedance qhia tau hais tias qhov tseeb resonance ncov ze F0 (65Hz), uas ua rau cov khoom siv hluav taws xob tso tawm tam sim no mus rau ob npaug ntawm qhov zaus band.
💡 Kev xyaum teb: Tus tsav tsheb 4Ω yuav tsum tau ua ke nrog Chav Kawm -D amplifier uas txhawb nqa 4-16Ω dav impedance load, lossis ib qho uas nws qhov tsawg kawg nkaus load tau qhia meej tias yog 4Ω. Yog hais tias lub amplifier tsuas yog txhawb 8Ω, hloov mus rau 8Ω tus tsav tsheb version (rated fais fab feem ntau poob rau 15W, tab sis distortion nyob twj ywm controllable).
Thaum xaiv tus tsav tsheb, nug tus neeg muag khoom ib lo lus nug tshwj xeeb:Dab tsi yog qhov peak impedance tus nqi ntawm F0 hauv impedance nkhaus?Daim ntawv qhia tshwj xeeb uas tsuas hais tias "4Ω" tsis txaus; koj xav tau tag nrho impedance - zaus nkhaus.
F0 65Hz + 88dB Sensitivity: xam qis-Frequency Extension thiab SPL
Ob lo lus nug feem ntau rau cov kws saib xyuas theem yog "yuav ua li cas qis qis mus tau" thiab "ntau npaum li cas dB ntawm 1 meter." Qhov no yog ib qho teeb meem lej:
F0=65Hz: Dawb- huab cua qis qis ntawm tus neeg tsav tsheb liab qab; nce mus rau 80-90Hz nyob rau hauv lub kaw lus kaw, tuaj yeem ncav cuag 55-65Hz hauv qhov chaw kaw
88dB rhiab heev: SPL ntsuas ntawm 1W / 1m; theoretical 101dB @ 1m nrog 20W amplifier input
Hauv engineering tiag tiag, ob qhov tseem ceeb no yuav tsum tau ntsuas ua ke:Yog tias koj lub tsev hais lus theem tsuas yog 3-5L hauv ntim, 88dB 5-inch tus neeg tsav tsheb sab nraud yuav poob 10-15Hz ntawm qhov txuas ntxiv. Lub hom phiaj tsim qauv yog 8-12L ( kaw) lossis 10-15L (ported), tso cai rau F0 txuas ntxiv thiab rhiab heev ua raws li tau teev tseg.
⚠️ Feem ntau yuam kev: Cov pab pawg ua haujlwm feem ntau qhia cov lus teb zaus raws li tus neeg tsav tsheb tsis muaj teeb meem, tom qab ntawd xaus - cov neeg siv cov lus teb hais tias "bass tsis txaus." Qhov no yog ib qho teeb meem tsim enclosure, tsis yog teeb meem tsav tsheb. Nyob rau hauv 17 xyoo, XDEC engineers tau hais txog 200+ theem hais lus enclosure txuam rooj plaub, thiab qhov xaus yog: txhais lub ntim ntim ua ntej, ces xaiv tus tsav tsheb.
Vim li cas 88dB rhiab heev tsim nyog rau theem saib xyuas?
Theem saib deb ntawm tus neeg ua yeeb yam feem ntau yog 1-2 meters. 1W/1m 88dB + 20W amplifier=101dB @1m @20W. Qhov tseeb SPL ntawm tus neeg hu nkauj pob ntseg yog kwv yees li 95-99dB, muab lub taub hau txaus rau kev saib xyuas lub suab. Rau cov theem loj loj PA (10-20m nrug), yuav tsum muaj kev tsav tsheb siab dua lossis ntau tus tsav tsheb sib npaug.
20W Rated vs 30W Max: Lub Hwj Chim Loj Npaum Li Cas Koj Yuav Tsum Tawm?
Ib daim ntawv 5-inch sab nrauv-magnet tsav tsheb spec feem ntau qhia ob lub zog muaj nuj nqis: 20W rated thiab 30W max. Yuav siv cov no li cas?
20W ntsuas lub zog: Kev ua haujlwm tsis tu ncua 96-teev kev kuaj xyuas (dawb suab nrov 50Hz-20kHz)
30W max zog: Short- lub sijhawm ua haujlwm siab tshaj plaws, tsis yog lub sijhawm ua haujlwm ntev -
Lub hwj chim headroom yuav tsum ua raws li cov1.5-2xtxoj cai: amplifier tso zis hwj chim Tsawg dua los yog sib npaug rau tus neeg tsav tsheb rated zog × 1.5. Yog tias lub tshuab hluav taws xob 30W tsav tus tsav tsheb 20W, siv sijhawm ntev - siv sijhawm ntev yuav ua kom lub suab coil kub tsis tu ncua (100W tsav tsheb tuaj yeem ncav cuag 80℃suab coil kub; 5-nti 20W tsav tsheb tsis ncav cuag qhov siab, tab sis enamel hlau rwb thaiv tsev txheej txheem kev laus yog tib yam).
💡 Engineering kev pom zoo: Chav kawm -D amplifier qhov tseeb tso zis zog feem ntau yog 10-20% siab tshaj qhov ntsuas (suab paj nruag teeb liab crest yam tsawg dua lub suab nrov dawb), yog li thaum xaiv lub amplifier,rated zog yuav tsum tsis txhob ntau tshaj 1.5x tus neeg tsav tsheb rated zog. Qhov kev paub no siv tau rau txhua tus W-chav kawm sab nrauv- cov tsav tsheb hlau nplaum, tsis yog 5-nti qauv xwb.
