I use EV zlx12p's for monitors. They work great for a really affordable ($350) 12" monitor, but they do have this slight buzz that does kind of erk me, that's with nothing even plugged into the back. They are really light (34lbs) which is good for moving around, but they get scratched very easily and just don't seem real solid, it's a hard plastic that feels chintzy, that said I've been driving them for a couple years without a problem.

I just helped a nearby venue buy a TruboSound ix12, for $300! It weighs 10 lbs heavier than my EVs, feels much more solid, it's more of a hard rubber that feels durable, has no hiss whatsoever and it has bluetooth streaming. I am really impressed with it and plan to buy an ix15 or two to add to my monitor supply. They are a great deal! That said, just after Christmas their price went up to $400, and most US online shops are waiting for more supply to come in without an expected date. . . still a great deal though IMO, worth checking out.

I know you were asking about Presonus speakers, but I don't have any of those. I'm am one of those guys that is always looking for the best possible unit for the cheapest possible price. I just don't have the budget for anything else. That said, when a big shot grammy winner or someone like that comes on my stage they still expect everything to be perfect. . . and it is.
