Sorry, I had a really bad day and was not in the mood to be corrected. But it does matter when the speaker is pulling and when it is pushing in comparision with other subs. Not only will there be really weak bass, it could also cause extra distortion at loud volumes if you have the subs in a box where the cones are in the same sealed chamber. Because when when one is pushing and the other is pulling it is equalling out the air pressure inside the box. Part of the reason a sub in a sealed box needs more power is because the air inside the box is working against the cone. If there is no place for air to get in when the sub pushes out, it creates a vacuum inside the box, pulling the cone back to it's middle position. The same is true with the opposite when the cone is being pulled in. There is no place for air to escape so the pressure in the box pushes the cone back to it's middle position. Now when you take that vacuum and pressure away it's like when you play tug-of-war and the dother side just lets go of the rope, or are trying to push a door open with someone on the other side and then they just step away from the door. You are still pulling or pushing with all your might, but there isn't the same resistance there was before so you end up pushing or pulling too far. This could make the cones bottom out, creating distortion.
) In conjunction with other out put transducers one being out of polarity will cause reduced sound , not just bass , but bass is far more evident.
