I don't get where you're going to put those tower speakers. If you put them on the floor, they're probably too low, if you put them on a desk, they'll probably be too high and your system on the right seems to be in the way of either option.
I measured height/depth. The tweeters will align dead nuts with my ears when I'm in my chair. They are deeper for sure, but they'll fit where I want them. Now, I will need to relocate or get rid of the second monitor. The only thing I use it for is Discord and temp monitoring. I can temp monitor on my phone via the Logitech G software, and really the same goes for Discord. I'm not married to the second monitor, so I'm ok with putting it up.
And yes, I know that it seems to be a little out of position due to the system on the right, but I've been using the Sony's this way for four years at this place. I simply played with channel settings until it sounded balanced, and it works for me.
However, I am having some second thoughts, and I think it has more to do with tier jealousy more than anything. Heritage(The Sixes + sub) vs Reference.
But, if they don't fit, I'll return them
