the krk rokit range doesn't represent the bass properly. The vxt larger range does.
I'd go for focals. the 80s. If it bleeds out in the living room, that'll be fine. This will give you a better bass representation then monitors sub combo tbh.
If you can't find the focals in America, JBL LSR 308, Tannoy Reveal 802, Mackie Mr8 or the HR824, Presonus Scpetre S8, you getting in higher price ranges though. The Focal would be best of all of these imo.
For treatment, watch some studio rescue youtubes,

I have the same thing
It doesn't bounce back to my sweet spot so it doesn't bother me but if there's ppl at home or my neighbours are home, the don't like it much
Anyway, my 2 cents. Focals, big woofer speakers will give you LOOAAAAAADDDSS of bass. IMO, better then speakers+sub combo. And some treatment.
Also, those options will keep you under 2k, most of the options. I have a few self built mid range grot boxes (inspired by auratones, legendary speaker, DIY
https://amazingdiy.wordpress.com/2012/05/05/davetone-mixcubes/ ). I have two of em but I have built in a mono switch for em. They'll complement your mixing a lot. You can buy premade like avantone or behringer and a few others.
