salut. am un amplif marantz pm35 si boxe esl( dif vestra). la volum mic( de surdina) 2-3 se aud ok, dar daca urc pana pe la 5-6 o boxa se aude mai tare decat celalta, ma refer la voce, inaltele mai "inalte" basul mai adanc. daca trec de nivelul ala 5-6 si asc normal pana pe 50% nu se aude nicio diferenta, sunet liniar, in centru, fara distorsiuni. apoi daca trec de 50% pana pe la 60-65 iar se aude o boxa mai tare , cas i cum una e legata la un amplif si cealalta la altu. iar dupa 65% abia se mai sesizeaza o urcare a volumului, ramane acolo, pot s adau si la 100% nicio schimbare.mentionez ca asc la un cd philips, indiferent de cd originale/cumparate sau facute de mine /audio. boxele le-am schimbat intre ele , nu sunt problema.ce poate avea?cat ar costa reparatia ? multumesc
