Difference between vented boxes sharing space, and not?

nope never been to a movie theater..... regardless, the only way to get true stereo separation at low frequencies you would need to wear headphones. In an open room even if you had a subwoofer on 2 opposite sides of the room your brain cannot detect where it is coming from anyways so it defeats the purpose. In a movie theater setting they have 5 to 7 discrete channels that allows them to play sounds through each speaker independently but that doesnt mean you can detect whether or not the bass is coming from the left or the right side due to its omnidirectional characteristics.

errr, the subwoofer knows what note it is playing and if it is run in stereo sharing the same chamber it can cancel out the other sub because its SHARING THE SAME CHAMBER. you dont have to be able to notice anything, the problem is going to occur regardless.

how many people run their subs in stereo vs mono? probably not enough to worry about it, and if they do, they probably have taken this into thought.

OP, your substage is mono or stereo?

Honestly, no one runs a stereo subwoofer setup. I'd go out on a limb and say that less than .1% of people on this forum intentionlly run a stereo sub setup.

meh... the difference would be so small between the left and right signals I wouldn't even worry about it. I wouldnt even want a stereo substage if I could achieve it in an automobile. This is not the point of this thread though....

right, but as it was explained in this thread separate chambers arent solely for bracing. i was giving another example to why separate chambers would be used. and ill bet that there are a few people on these forums that are bridging a 4 channel x2 in a shared chamber lol..

you'd have to try very hard to make it work and sound "stereo"

probably cuz thats what they have VS thats what they want. lawlz

I did that in my temp setup I just got rid of. A pair of IXL10's powered by a Cadence DCA-4100(250x2 bridged). It was the same mono signal from my HU though, just used some RCA splitters before the amp so I could get a signal to the left and right inputs on the amp.

The subs were in a shared 4ft^3 chamber...sounded great too. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

im not saying people are "trying" to get a "stereo sound" they just see a left channel and connect the left sub to it and a right channel and connect the right sub to it and use a shared chamber for a stereo signal. when you would need separate chambers to get optimal performance from your subs with your amplifier set up that way.

depending on the signal the amp is getting. if it's a split L/R from the HU then yes, but if it's a spliced (read "y'd") signal, then it's still mono. but thats not where this thread was headed...

and if you can't notice it, then it shouldnt matter. it wont hurt the subs.

you may not hear the "stereo sound" but you will hear the cancellation caused by 2 subs playing on diff channels in a shared enclosure.

99.9% of people have HU's that are not capable of providing L and R sub signals, so the point is moot since you'd still be providing the amp with a mono signal, albeit in two channels.

well for one, you wouldnt want a shared chamber if you were running a left and right channel sub in stereo.

Most of the bass notes in music aren't recorded in stereo so it doesn't matter.

In an open room even if you had a subwoofer on 2 opposite sides of the room your brain cannot detect where it is coming from anyways so it defeats the purpose.

The majority of home theater receivers don't have stereo subwoofer outputs also.

Indeed.
