[QUOTE="cotjones, post: 6648323, member: 573988"] In all fairness. That was extremely wordy, and hard to read compared to most posts on this forum. The short answer is this: Think of the subs by the airspace they occupy. (2 subs in the same box with no divider inside are using the same airspace.) Obviously, when a sub hits, it creates air pressure inside the box. Now If you have 1 amp powering 2 subs, It's generally acceptable to let them share the same airspace. This is because the subs HAVE to be playing the exact same frequency, and thus when they hit, they both hit at exactly the same time and with the same exact signal, meaning the pressure caused by the subs hitting would counter-balance between the subs. (In layman's terms: If both subs push at the same time with the same force, neither over power the other. But if one has a slightly different force, One will overpower the other.) This can cause a sub which is at its maximum excursion (or distance from the resting position) to exert farther due to being pushed by the air pressure of the other sub(s.) For this reason, 2 separate amps powering speakers that share the same airspace is not ideal. It might not seem like it, but 2 different amps will NEVER produce the EXACT same signal. The difference isn't likely going to be enough to hear, but a sub cycling at 40+ times per second feels even slight differences very very much. So if your sub is playing a reasonably common tone (say 40 hz) and the signal between the subs is 1/80th of a second off, Your subs are playing opposite polarity which basically means one of your subs will blow easily with half of the power it can handle in a proper enclosure. To simplify all this. here are examples of multiple sub setups: Same airspace, 1 Amp = [IMG]//content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif[/IMG] separated airspace, 1 amp = [IMG]//content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif[/IMG] (but not necessary) Same airspace, Multiple Amps = [IMG]//content.invisioncic.com/y282845/emoticons/thumbsdown.gif.d22f25895e9b40f2300c953691dacfa2.gif[/IMG] Separated airspace, Multiple Amps = [IMG]//content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif[/IMG] [/QUOTE]
