Buna ziua ,
Multumesc de raspuns !
Optam pe 3 cai , ca dispun de cateva difuzoare de medii . Le am incercat si mi plac cum se aud
Boxele , le voi folori pe un amp pe lampi !
Credeti ca o incinta de 45 l , acordata la 50 ar fi ok ?
Multumesc anticipat !
Cred ca in descrierea produsului ai toate datele necesare, poti face o simulare cu WINSD sau Bassbox.
