Thank you, you sonarians are awesome

$200 is tough. IK's Micro Monitors are amazing (the link is to my review on Harmony Central), but they're $299. A set of Rokit 4" speakers will set you back $280. Have you considered headphones? KRK's KNS-8400 headphones are voiced like studio monitors and cost around $150. You have to get used to mixing on headphones, but I've used them a lot while on the road.

 

Closed back sort of flies in the face of conventional wisdom on mixing headphones. I am not really contesting your choice, but just wondering why you chose those. I am never on the road, but also never in an optimally  treated listening environment.

An article in Sound on Sound pretty much nails it: “Open-backed designs have grilles that expose the drivers to the outside world, which in turn reduces resonant cavity effects and inherently provides some cross-feed between the ears, giving these designs a more natural and 'airy' sound when mixing. However, they are of little use for performers during tracking because their sound will spill into your mic recordings. For this purpose, closed-back headphones are far more suitable, and they're also better for mixing if you're in a noisy environment and want to block out the world.”
 
I'm often doing narration or something else involving voice, so that's part of it. Also when mixing, noise sources like hotel room air conditioners make using open-back headphones impossible. Furthermore, the KNS 8400 headphones are voiced specifically like studio monitors; I can trust the bass. They're also very light, so I can handle mixing for long stretches at a time.
 
Anyway back to IK's Micro Monitors...if you want to use speakers, they really are as good as you'll get with something that compact. Even the bass is pretty tight, not mushy.

Exercise a little more patience and save up about 90 more dollars and get a pair of JBL LSR305's.
If you spend 200 on a pair of monitors, you'll probably end up yearning for some better monitors after a short time, which will cost you more money in the long run since you'll end up dropping more on a better pair. IMHO
 

I would also recommend the KRK KNS 8400 headphones, and combine them with the Focusrite VRM box and (IMHO) you have yourself a very useful mobile mixing studio as the VRM box not only recreates the speaker crosstalk but it also emulate lots of different speakers and listening environments to test your mix

I am not saying any single one is a replacement for God monitors in a related room but the ability to flick between different emulated speakers really does expose mix issues. The VRM box is discontinued (I heard that as it was USB 1.1 so there were issues with USB 3 ports) but if you have a USB 2 port I think the KNS 8400 / VRM combo is a stellar mobile / small footprint mixing solution

You might also want to check out your local pawn shops for a good used pair. I know ....I'm cheap!! but that's were I found mine.

I recommend JBL LSR305 studio monitors.  I found my mixes sound consistent on every system I've tried them on.  I see there are several on sale at:  https://reverb.com/p/jbl-lsr305-active-monitors?_aid=pla&hfid=1263950&gclid=CjwKEAjwydK_BRDK34GenvLB61YSJACZ8da3s27HgEOaBnPF3QUEH2N00ymbkTEZdElTdEO4X_6inBoCIvXw_wcB
 
They seem to be in your price range, I found them to be very accurate.
