Ajutor in reconditionarea unor SB-M300


Recommended Posts

Am cumparat niste boxe technics SB-M300 second hand cu ceva probleme.

- Ambele tweeterele lipsa

- Un difuzor de medii ars.

Am vazut ca dif-ul de medii-bas este pe 16 ohm!!! Nu am gasit si am cumparat de 8 ohm.

O sa adaptez filtrele ca sa nu se modifice frecventa de taiere. Circuitul zobel il las asa pentru ca am inteles ca valorile respective nu sunt critice.

Acum intrebarea mea este: Daca am pus dif de 8 ohm in loc de 16 acesta se va auzi mai tare? Trebuie sa ii fac o atenuare (L-pad) de 3 sau de 6 dB?
