If you wanted to go the studio monitor route, i'd buy passive. You can get rokkit R6 as passive monitors and connect them to a proper amplifier. Remember to note that these are nearfield monitors which need to be within about 4-5ft of the listener.
In any case, the biggest reason why you don't get a flat response is the fact the the speakers you use are not operating in an anechoic chamber. Where you place them in the room, the room size, room shape and objects near to the speaker will all effect how they sound. sticking speakers near to walls or in corners will increase low frequency levels as will smaller room sizes. The level of soft furnishings in the room will affect HF levels and reflection interference and so on.
This is the frequency response plot for my home made Kef chorale. Not likely to get much flatter than that.
This is another plot for an LS3/5a design (modern drivers rather than vintage Kef, due to cost and availability) that i've been working on. Again, very flat. (note the nasty impedance plot, suggests it might be an awkward load for some amps)
Note that the first speaker is a hi-fi bookshelf speaker, the LS3/5a is a BBC monitor designed for speech work in OB vans. (mobile studio) I highly doubt that either would perform anywhere near flat in my room, simply because my speakers are squished into the corners of the room and i little in the way of soft furnishings.
