I would go with the Avatone Mix Tower. A 3 way monitor with 2 different modes. They run around 1400-1600 a pair.
The AVANTONE PRO MIXTOWER loudspeaker system, is an extension of the renowned AVANTONE MIXCUBE. Many production environments do not have the space for multiple speaker systems, so we developed the MixTower as a dual purpose monitor. The custom MixCube driver is mounted in an isolated box the exact dimensions of the MixCube. Run in MixCube mode, the driver responds full range, just like the MixCube. Run in three way mode, the driver is crossed over at 120Hz and 8000Hz to give the system a more natural studio monitor sound.
The Mix Cube was the standard reference monitor before the NS-10. It was made by a company called Auratone back in those days.
