Pai banuiesc ca trebuie calculat ca orice incinta cu bass reflex....numai ca trebuie sa fir acelasi volum si la cilindrul acela care trebuie sa il folosesti....banuiesc...nu am gasit inca program sa calculeze si incinte cilindrice...:(

Am introdus datele tale in program...si mia dat pt subwooferul tau o cutie de 204 l si gaura de bass reflex are diametrul de 10 cm si lungime de 6 cm ..... revin mai tarziu sa iti spun cam ce dimensiune ar trebui pt tubul tau....daca gresesc sa ma corecteze cineva.

Normal volumul til calculezi dupa formula de clasa a-8-a ..... V=pi * R la a-2-a * H...... V la tine este de 20.43 cm cubi , R este de 20 si H care nu il cunosti si trebuie calculat este inaltimea.... eu am calculat dar imi da cam aiurea...mai studiez putin si revin...

urmariti daca am calculat bine....deci volumul = pi x raza la patrat x lungimea...ca sa am 55 litrii in tub...tre sa-l fac de aprox 45 cm...el avand diametrul de 40 cm deci : volumul = 3,14 x 400 x 45 = 56, 520 litriice ziceti am calculat bine?????ce pun in interior ca material fonoabsorbant si cat?????la capete voi taia la un meserias 2 ronduri :axe: si diful la o parte si br dincolo....sa incerc...prima data ma gandeam la un cabinet...bandpass 4....dar o sa incerc treaba cu tubul.....daca tot a fost de-amoaca... :rolleyes:
