So, my the promedia 2.1s that I've had for about seven years decided that they no longer like me, so I need to replace them.

 I live in a 600 sq ft studio. Neighbors aren't really an issue, but I also don't blast my audio. These will be on my desk, and I can MAYBE go an inch or so taller than the Pro Media satellites. Same with width. The only place I have some wiggle room is depth. Image above basically shows how much space I have.

  
I would like to stay with a 2.1 setup, UNLESS I can get just as punchy bass from just a pair of desktop speakers. From the speakers I've ever tried(albeit my previous budgets have been much lower than they are now) the bass sounded very hallow. I never felt the ones I heard had any sort of bass depth. Feeling bass>hearing bass to me.

  
I don't mind going with powered or unpowered, but the MAX budget is 400. I would prefer to come in around 300, but I'm willing to go 400 for the right setup. I do currently have a headphone Schiit stack, that I've had for about four and a half years. Magni/Loki/Modi, and I think that the only thing in there I can use with a new setup that needs it's own amp are the Modi and Loki, and I'm fine with that.

  
I don't care if they have bluetooth at all, as I never use it. I have an X570 Crosshair Hero VIII, and it has optical, usb and the standard 6 spots to plug audio stuff into.

  
I prefer a clean audio, quality is always better than quantity. I want something that's fairly level, but maybe a little less in the middle and more on the highs and lows. I should be able to handle any small adjustments with my Loki though.

  
I'll be using these for TV shows, Sports, music, and movies, and connected to my computer. I don't have room for stands or anything like that. They have to fit on my desk.

:( Need to replace my ProMedia 2.1's... Max $400 budget.
