[QUOTE="Buck, post: 8861099, member: 591582"] Technically not correct, but the difference here would be minimal. Air itself has a resonance to sound based on density, so when you split chambers up, it splits the air into smaller groups, which causes higher resonance sections because of more dense air per chamber and some 1/4 wave stuff; one side of the box is a wood wall instead of an air wall, like a cushion. So, with 2 subs, splitting the chamber in half will make both chambers resonate slightly higher. You can look at Fc or Fsc of a sealed box to see that. Doesn’t mean it’s incorrect to do it that way either; sometimes you gotta divide chambers up to raise resonance, for structural integrity reasons related to the box or woofer moving parts. It’s a similar thing with ported boxes, where if you have a ported box with multiple chambers, you’ll need slightly larger ports to maintain the same port velocity with the more individual chambers you add, vs a single large chamber, which can use a smaller port if you have 2,4,8 subs, whatever, all in a single shared chamber. This stuff makes a difference when you have a wall with 16 subs in it and 30,000w. [/QUOTE]
