I had some floor mounts that were fatiguing in my space and tried a variety of other speakers to improve on that. The best I heard and now own are the Ascend Acoustics Tower with RAAL tweeters. This small, engineer-owned company from California does not do much in marketing or advertising and does not churn out one model after another. I have listened to a lot of speakers for a lot more than the Ascend and they really beat out a lot of competitors -- to my ear.
Right now there's a pair at TMR which, for your budget, would be a no-brainer. https://tmraudio.com/speakers/floorstanding-speakers/ascend-acoustics-sierra-tower-v1-floorstanding-speakers-satin-espresso-pair/
For a bit more, you might try this speaker in its very recently upgraded version: https://ascendacoustics.com/collections/elx-series
