if u want one ass out and one normal, you'll need to swap pos and neg round on one and the 'normal' one will need some polyfill in the box to make it 'seem' larger. | |

Well they work exactly the same as 'normal' sealed boxes. All a sub technically is, is a diaphram moving air driven by a motor, its just flipped around that way. They are all correct in saying that the box will act asthough its bigger due to the loss of displacement of the motor structure/frame etc. Sometimes people alter the phasing when they flip subs but to be honest their is no need but just try it anyway to see if it gives an improvement. Personally i do think it looks good but when i did it to my Type R's i found it very difficult to get a good air-tight seal and also gome some slight motor noise at full wack, they just didnt seem to hit as hard as the 'normal' way. You may not even need to alter the box you have, it will increase the volume inside but it may still be withing the manufactures recomended volume tollerances. Just try it out and let us know. Another BIG tip is to use some things called T-Nuts to bolt subs into enclosures, you can do them up REAL tight without the worry of stripping threads in MDF. They cost mere pennies and if you are playing around a lot with box's then they are very handy. Good luck.. :thumbs: | |

Yup, Steve's right. The box dimensions have to be altered to allow for the lack of magnet inside the box, hence a smaller enclosure :D | |
