[QUOTE="066, post: 8823986, member: 687517"] I appreciate the input. So my box as planned is 4.2 cubes. Cross area is what you’re referring to right? 6” is 28.27 so on the very low side of what you said. I’ll model the 10s for kicks. I can still return the 12s. For now, I already have the 12s and I like how they sound but the sealed box they’re in won’t let them dig. It plays a 30hz test tone well but there are a few songs I listen to that they won’t hit at all. Keeping in mind these subs have an fs of 24. I’m happy with output even in sealed right now but not below 30hz. Why is that the wrong tuning? The graph looks good to me? My goal is to get lowest, not loudest I’m open to face them upwards. Port direction shouldn’t matter as long as air velocity is right i guess? I understand the dual opposed should cancel box vibrations, but you’re thinking I’ll have sound cancellation? Is this a road you went down before lol? Everything I can find has been about home audio. Anything you can point me to focused on car audio? Thanks again. [/QUOTE]
