hi guys, i have 2 old 10" oz subwoofers and i wanted to build a box for them that is divided and ported but i don't know the reccomended cubic volume for each one and the port size. they are very old and i cannot find any information on the web and the model is not on oz's website. the subs are rated at 350rms and 700 max power if that helps. maybe someone who had these subs can help me if not can somone reccomend me some dimensions? thanks
