díky za ohonocení pro stabu dom subu

Myslím ža aj hej pokiaľ nevaqdí väčšia bedňa vychádza mi s tým tak 130-150l ladené na 38-42 Hz, no je otázne či to pojde dost hlasno v nízkych frekv pod 50Hz lebo už padá citlivosť. Na PA by som dal bednu tak 100-120l a ladenie 47Hz.

Tak to to k tomu ještě přišlo ,jedno je na 90 litru a druhé je na 180 litru
Určitě to jsou parametry surového repro , ta se to po rozehrání změní je to tak ? A jakým směrem se to pohne a co se bude hejbat ? Ještě mám dotaz na rozehrání jakým zpusobem to rozehrát _ díky všem za rady

tak jsem zkusil něco nasimulovat co vy na to

No podle parametrů to nebude uplně to pravé do subu,hádal bych, že to má poměrně nízkou cívku, ale hrát to nějak bude......
