I asked this question at the end of a different post but it was a little OT and I didn't get any response. I hope it's okay if I ask it again in its own thread, I'm just trying to learn as much as I can from you guys.
If I do the sub crawl with my current subwoofer and find its best position will I have to repeat the process when I buy new a subwoofer to replace the old one? The new sub will be larger and much more powerful.
It seems to me that it would not be necessary but I read in a post where someone replaced their old sub with something more powerful and since they had already done "the crawl" for the old sub they just assumed the new sub would go in the same spot. But the new sub never sounded as good. Finally they did "the crawl" again and found the new stronger subwoofer sounded better in a different location than the old weaker subwoofer. I believe both were ported subs (if that makes a difference).
Does anyone have any knowledge about this? I don't mind crawling around my room more than once if need be but I do find this curious and would like to learn about why bass waves between two different subwoofers would vary to the point of there being different sweet spots for their placement in a room.
I hope I wrote this in a way that made sense. Thanks for any help.
