Yuav Ua Li Cas Xaiv Horn Line?

Audiophile tau zoo heev rau kev xaiv ntawm horn kab them mloog mus rau, puas tau hnov ​​yog tsis muaj tsis muaj leej twg siv kaum txhiab multivariate yuav ib kab; Lwm qhov kawg ntawm horn kab yog txuas ib lub xov hlau casually thiab ua suab.

Dhia tawm ntawm ob qhov kev kub ntxhov no, pom qhov kev xaiv ntawm txoj kab horn los ntawm lub kaum sab xis ntawm lub tshuab, tus neeg xyuas pib zoo heev yeej' tsis muaj lub suab zoo pom meej vim tias qhov kev tawm tsam ntawm cov kab zoo yog qhov loj, ntau lub zog yuav raug siv rau ntawm tsis kam ntawm tus neeg xyuas pib, qhov poob ntawm cov ntses bass thaj tsam yog qhov tshwj xeeb. Cov xov hlau tuab tuab heev muaj kev tiv thaiv me ntsis, tab sis khib nyiab thiab nyiaj txiag. Kev poob (kev poob qis) ntawm cov xov hlau hauv qab 0.5dB feem ntau suav hais tias yog kev zam. Los ntawm lub suab tso zis mus rau lub suab nrov nyob rau hauv ib feem ntawm lub Circuit Court, qhov impedance ntawm tus hais lus, qhov ntev ntawm cov hlau, thickness ntawm cov hlau yog ib qho tseem ceeb heev, kev xyaum dav dav yog xam cov thickness ntawm cov hlau raws li qhov ntev ntawm cov hlau. hlau thiab impedance ntawm tus hais lus.

General hlau txoj kab uas hla

Cov duab hauv qab no qhia txog kev sib raug zoo ntawm txoj kab uas hla ntawm 100 ft ntawm cov xaim, hais lus impedance, thiab qhov poob. Piv txwv li, 30 meters kab 18, 4-ohm impedance loudspeaker, insertion poob yog 2.5dB, txaus loj. Raws li koj paub, qhov poob ntawm 3dB txhais tau tias poob ntawm ib nrab ntawm cov zis ntawm lub amplifier!
