BMR Towers. 43" high, phenomenal performance at $4000. Or JBL Project Array 1400s, if you can find them. They’re gonna be 6-8 thousand bucks if you can. Not many people turn loose of them. They’re about 45" high. Best imaging I’ve experienced.
Stereophile website has a great review of them from about ten years ago.
+1 for the Ascend Acoustics. I haven’t owned the towers, but the Sierra 2 EX is a very fine speaker. I suspect it’s similar to the BMR Tower, using the same family of drivers, top and bottom.
