funny I have two 15"s mounted inverted and the polaritys are reverst and they are playing fine and if you wire reguarly they sound like ***.

You are only "REQUIRED" to do it when one is normal, the other is inverted.

When both are inverted you can do it anyway you want. As long as the 2 drivers phase match. Both reversed or both normal.

Like triger said, and I indicated in my first post, only switch the polarity on the sub if one is inverted and one isntnt. If you have two subs mounted inverted, you wire them both normaly

i tested max spl of my inverted mag 12s wired both correctly and reversed... same score both ways... so.... no it doesnt matter

And one test is enough to make an end all statement:eyebrow: And how exactly did you test it???

It's all very simple. Just make sure to keep the subs in equal phaze. Or cancelation could be a problem.

Were they both inverted??? If so there would be no difference, or was one inverted and one not, because im sure there would be a difference there.

I think people are getting confused about being able to wire subs either way and have it not make a difference because they don't realize that the musical power that comes out of the amp is ac not dc.

And there is no reason why the scores should have been different.

What it does change is how the subwoofer blends and integrates with the rest of the system. Sheer output level will not change, however.

Ya'll make everything more confusing everytime a question is asked.

If I wanted a smaller enclosure, would inverting allow me to lose some enclosure volume? If so, how much (I'm thinking just driver displacement, but I want to make sure)?

yeah, you just gain driver displacement. But you have to remember that the enclosure will take up more room with the subs inverted, mainly because you have 6 0r so inches of subwoofer hanging out of the box.
