 Otpore napravi paralelnom vezom 10x1W.

Koje otpornike preporučuješ?

Pa Krle, kako bolje da opisem? Kupio da probam kako ajde na oko solidna izrada, pustio i jako loše zvuče.

Na prvu loptu je i meni bilo što li bacih pare. Kasnije prosviraše. 2,2uF mi je na visokotoncu. Znači 7 komada što je opet jeftinije od Benica. Probaću.

Bilo koje za start. Nikada to nije od prve. Tako da racunaj da ces to menjati. Predlazem ti 1W MOX ali 10x u paraleli (na primer treba ti 2.2oma onda 22oma II...).

Kad ugodiš vrednosti, stavljaj koje hoćeš

Ne verujem da to usviravanjem ili bilo cime moze da se popravi kod tih C. Ima i drugih... :)

Nisam upisao da je na mid basu kalem 2,45 mH a na visokotoncu 0,47 mH.

U Kelco -->  Vitrohm - MOX, 2W 

http://kelco.rs/katalog/komponente.php?IDgroupweb=150

Za te vrednosti 3,3 Ohm --> 3*10 Ohm (ukupno 12 kom.) a za 8,2 Ohm --> 4*33 Ohm (ukupno 8 kom.)

Snaga više nego dovoljna. Ako visokotonac "troši" 7W, a redni otpornici 6W. To je ukupno 13W. Ni do pola toga neće stići otprilike nikada.

P.S. Ako se hoće veća snaga za taj 3,3 Ohm na mid-bass-u, onda 3*18+3*22. (12W)

PS2 Ko može da čeka, naruče se iz Mousera --> fancy KOA Speer resistors MOX 2W.
