Sub Box Questions
I just recently purchased a pair of JL Audio 13.5 inch Subs, but they
were installed in a box without a divider to seperate the two speakers airspace? Does this even matter? Should these also be completley sealed air tight? Thank you! |

Sub Box Questions
It doesn't matter unless one gets blown, as at that point the paramaters
of the box change for the remaining good speaker, and will be more likely to cause damage to it.

Sub Box Questions
A divider is not needed for subs. If your box is a sealed type then yes it
should be air tight, if it's a ported type it should have an opening/s.

Sub Box Questions

of the box change for the remaining good speaker, and will be more likely to cause damage to it. Brandonb Heed Brandonb's warning. This can, and does happen in the real world, especially with high-power subs and amplifiers. In a sealed enclosure, the airspace behind a sub acts as a spring and helps control the motion of the cone. If one of the subs suddenly stops working, the air-space for the working subwoofer will suddenly be doubled and thereby creating a much looser spring. This will cause greater motion of the cone and a decrease in control that might lead to damage at high volume levels. For this reason ALONE, I always go with multi-chamber enclosures when building sealed boxes. MOSFET |
