[QUOTE="Buck, post: 8734386, member: 591582"] I did it to save a little space. Also too, if you're building, and you mess up one chamber, you get more chance for cancellation, vs if everything is grouped together into one airspace. Like if you need 2 cubes and one chamber is 1.0 and one is .95, then there will be some cancellation. But that's very technical and the effect may be minimal. I just design for what's needed in every situation. The box I'm designing now has both independent and a shared chamber. Usually one shared chamber and one shared port is what I generally like for ported. All that matters is that it's designed correctly, really. Sealed divided chambers vs shared is a bigger deal than ported. Some woofers can be damaged in shared sealed chambers. Going sealed, you can only go so much power up to a point, depends on the woofer. Surrounds can blow out. You also have to be careful how close you put woofers to corners in certain applications. There's been walls where woofers in certain corners blew way more often than others, seemingly due to the pressure increase in the corner. And dividing chambers up with multiple woofers in sealed changes the resonance of the sealed chamber some. Sometimes dividing chambers is about just plain strength, too. You need a big wall there for the power or the size of the box or something to keep the other walls from flexing. There's a lot I take into consideration when I'm designing. I don't get every one perfect, but I try to. [/QUOTE]
