Speakers Upside Down?

I know I’ve seen Zeos sometimes use his speakers upside down. So my question is does it actually make a difference as long as you have the tweeters at ear level?

It mainly is just for positioning in the room and for most speaker designs it shouldn’t really make that big of a difference in sound (in a negative way). It’s not something you have to do, its just if you need to there really isn’t harm in doing so
