Do you need to have a seperate chamber for each sub when going sealed??

Do you need to have a seperate chamber for each sub when going sealed?? Iam looking to do 8 8's in my crew cab in a mini wall, and I want to know if I can run them all in the same chamber if its sealed?? Any benefits/bad stuff??

Thanks!

Supposedly separate chambers are better for some unknown reason. Usually common chambers are more efficient though and you don't have to worry about getting both chambers the exact same volume or whatever, so odd shaped boxes don't give you a hard time trying to split the volume in half exactly.

So think I should try a single chamber sealed as long as the total volume is correct for the subs of course...?

I couldnt tell any difference between 3 15's in 3 seperate chambers, or common chamber, except they sounded like they got a little lower in the common

I used separate chambers so if 1 sub fryz I can still listen to the others. The walls inside the box for the separate chambers make good bracing.

That's what I was told to use separate chambers for. But honestly though, if you fry one of your subs, that's your fault, not the box lol. And ontop of that, who would still keep listening. I would replace the sub.

And on a side note, bracing isn't really needed in sealed applications, build very low SPL in relation to a ported box.

Shouldn't make a whole hell of a lot of difference unless you are running them off of more than one amp. Then you may see some cancellation if the amps aren't matched up perfectly. As long as it still is solidly braced I would just run them common chamber for ease of construction.I used to run four and then eventually six sealed tens years ago and never had any issues going common chamber.
