[QUOTE="mat3833, post: 8804988, member: 587645"] 2 is technically unnecessary, but the way it was explained to me(from a home theater perspective, doesn't translate exactly) is as follows: For a given sub size tuned into the high 20s you will want to either run a PR one size bigger(Ex 12" sub = 15" PR) or run 2 PR of the same size. The benefit of running 2 PR is you can place them on opposing sides of the enclosure to cancel out the vibration they can cause. A port moves a TON of air at tuning. So you would want a PR with 1.5x more Xmax than your sub has at minimum. Passive radiator enclosures are more art than science. Each PR behaves slightly different than another and it will usually take a bit of tuning and testing to get it to perform how you want. They also don't model very well because there are a ton of variables that need to be taken into account. Matt [/QUOTE]
