It don't matter, you can do it either way. I prefer going with the one box with dividers in it. Are you going to go ported or sealed? That will determine the air space you need per sub.

sealed all subs and amps are identical and will use a vibe deltabox to boost and split signal 3 ways :)

i'll prefer to put them in one big enclosure but with 3 chamber so that each sub can get it's own airvolume(cuft). if you put them in one big enclosure with no chamber so they share the same airvolume, they will work fine, but if one day one of the drivers fails, chances are that the other drivers can be damage too. i.e. you have 3 10" subs and they require 1 cuft per subs, you put them in one big enclosure with no divider, so they share the airvolume, and if one of the subs doen't work good and fail, then the other 2 will get more airvolume, 3cuft for 2 subs, each subs will have about 1.5cuft and can damage the woofer depend on the brand and the cuft range they need.

If working proporly, not anything noticible i believe... other than you need to design the box 1.5" longer because the 2 dividers of 3/4" MDF in there taking up valuble airspace  ------------- 99 Blazer LT.

If it's a vented enclosure, you put all three in the same chamber, and one dies, you could have a potential problem. But in this case, if one dies, and you have an extra cubic foot or so for the other two subs to split, it doesn't matter. It won't damage your subs, it will just give them a little more low end response.

The recommended sealed box is between 0.7-0.8 ft^3 per sub.
