I was actually looking at iLoud for monitoring Kemper. Hoping it have flat sound like the studio monitors.
While I have no experience with iLoud, they're not advertised as reference monitors or even FRFR for that matter. The only thing I saw in specs was the frequency response of 50 - 20k, which doesn't tell you anything about which frequencies might be disproportional.
It's not uncommon for quality consumer grade speakers that are designed for listening pleasure to be heavily hyped on the low end (even earbuds - listen to your song on reference monitors, then on your iPhone via Apple ear buds and you'll wonder who the heck dimed the bass knob when you weren't looking).
Side stepping for the moment the whole "guitar cab in the room" thing, at this point what you probably want to hear is an accurate representation - the good, the bad, and the cosmetically challenged - of what a given profile sounds like. This is what FRFR speaker cabinets and studio reference monitors are designed to do. While none are perfect, the goal of this style of speaker isn't to artificially enhance the listener's experience. It's to tell the truth.
With that in mind, even an inexpensive set of speakers that are designed for use as studio reference monitors will serve you much better than a random speaker choice with different priorities. Your iLoud example was $250. A pair of small powered Mackie reference monitors is $300.

If you want to go with an active FRFR speaker, I bought a Yamaha DXR-10 based in large part on how much love they get around here. It's certainly not the only one people like but it does sound great. This goes for $600.

You can spend five figures on studio reference monitors if you have a commercial studio, deep pockets, and can justify the expense. However, past a certain point, the benefits become subtle and aimed at mix engineers with golden ears. What you need at the the moment is "best bang for the buck." Mackies fit the bang for the buck category.
I still have a larger pair of HR824s as my main studio monitors. They're not sexy, and I could spend more money to get some subtle improvements, but they deliver great quality for their price point. I also have an earlier version of the smaller ones that I linked to above in my office / B room. And once you open the door to inexpensive studio reference monitors, plenty of other guys here will probably make additional suggestions since there's a lot of good gear out there at a low price point.
In your case, it's a matter of looking for the right kind of gear, and for something like the Kemper, you want speakers that tell the truth rather than enhancing any particular part of the spectrum.
That said, while you're saving your money there's absolutely nothing wrong with using the Yamaha to practice with in the meantime. Tweak it until it feels good to you. Then play guitar.
When you can afford to upgrade, either studio monitors or active FRFR guitar cabs would be my suggestion for the next step. If you want something you can take out and play with others, saving for long enough to get something like the DXR-10 would be a better choice then studio monitors. However, if you're only playing in the house for now, studio monitors get the job done and also help you build a recording environment. You can always buy an FRFR at a later date if you want to rehearse / gig with others.
