I'm trying to wrap my head around IB. Obviously the sub needs room on both sides to breath, I get that, boxed the sub in a standard enclosure, it's not going to preform well. Understood.
But I'm trying to better understand the wave cancellation impact. I presume when both waves (front/back) meet is when the waves cancel each other -- is that correct??? So, in trying to get a better handle on this idea, how far away does the back wave have to be from the front wave before the impact is no longer noticed?
Examples:
If the back wave (think Attic) is large and the front wave (think room) is also large, then what happens if the attic stairs are pulled down at the other end of the house? What if the stairs (back wave) were only 15 feet away from the sub's front wave, or in a hallway right outside the room opening? Do these types of open "leaks" have an impact on the output?
I don't see anyone keeping their attic open when playing content, but this question is less about the practicality, and more about visualizing how the IB works. Let's not get "hung up" on the specific examples, they only represent the thought process behind keeping the two waves apart.
Perhaps it's the intensity of the wave collision that matters? Meaning the further one wave must travel (including bouncing around in the attic) to reach the opposite wave, the less cancellation it will have. Hmmm, I like this theory best...
Thanks,
