vektor Posted February 6, 2008 Share Posted February 6, 2008 Ai fost la scoala ? U=IR Cum tensiunea constanta [asa sunt facute ampurile], daca pui r jumatate, ce se va intampla cu intensitatea curentului ? Asa, empiric, fara studii de specialitate.

lupul alb Posted February 6, 2008 Share Posted February 6, 2008 (edited) O iesire de amplificator nu e facuta in impedanta fixa. Depinde de impedanta boxei (boxelor) care e legata pe acea iesire. Impedanta mare=putere mica, impedanta mica=putere mare. In 4 ohmi amplificatorul o sa scoata o putere cam cu 70% mai mare ca in 8 ohmi. Nu stiu cum sunt amplificatoarele de casa, dar probabil ca merg si in 4 ohmi. Asta ramane sa verifici tu. Numai sa fi atent ce puteri compari, RMS, PMPO, etc pentru ca sunt lucruri diferite.
