Nu stiu ce filtre sa fac....... care sunt mai bune cele pasive sau active?Am cumparat condensatori pt cele pasive dar imi este frica ca nu-mi ies bobinele bine si nu stiu ce sa fac.Am facut un sistem 5.1 si nu am filtre! Astept pareri.......

Dar poti sa faci active.......Ai nevoie doar de un amplificator operational, alti condesatori de calitate, rezistente , stabilizatoare daca nu se incadreaza alimentarea amplificatorului in limitele operationalului. Avantaj: mai usor de intretinut si reglat. Dezavantaj: Ai cumparat deja componente pentru filtrele pasive :)Cat despre partea ca nu iti ies bobinele bine... prima o sa iasa stramba rau, a doua o sa uiti sa aliniezi spirele si a treia va iesi mai bine ca una de fabrica.Spor la treaba,Filipone
