I don't think you can come close to the finest PMC studio monitors installed professionally in the US on a $4,000 budget at least not new....but I guess you know this.
I agree with the suggestions already made on this thread so I won't add any specific recommendations.
However, in general, if you are very patient and keep looking, you could do what I have done; buy some old studio gear second hand on audiogon. My plain black ugly big boxes, with a few dings, came from a professional mastering studio. These type items do not sell easily on audiogon for obvious reasons - so just be patient and don't set your heart on one particular speaker.
