Although I can't use the word "painful" I also don't like bright sounding speakers. The smoothest, that's my word for easy to listen to, speakers I've owned are Meadowlark Kestrel Hot Rods. These speakers truly get out of the way and bring no attention to themselves. Very mellow. They are however, floor standers. I've ried to figure out which speakers use the same Peerless tweeter without much luck. I believe the Sony SS-M3 uses it or a variation. Those Sonys were nice sounding speakers.
I highly recommend these if they fit. If not, definitely find a speaker with a soft dome tweeter. Good luck.
