A used pair of ATC SCM40 V2 speakers would be right up your alley. ATC speakers are used by many recording studios because of their sound qualities. I heard a pair about a year ago and was very impressed. If listening to some, make sure they are well away from the front wall as this affects the soundstage considerably. They are well built, the exact size you want and have very rugged drivers with the ability to expose all that is on the recording. They look nice, in an understated way. The V2 speakers go for just under $7000 new. Although the specs say they go down to 48 hz, they have tremendous, punchy bass and seem to go way lower when listening. The bass had no whomp or boom to it. No need for a sub at all. Zero breakup in the sound at high levels. The mid driver is one of the best in audio and the tweeter in the V2 is now very good also. Vocals were beautiful and complex passages never got messy. Very dynamic speaker and the cabinet is heavy at about 75 lbs. for its 40" height. I own a pair of Vapor Audio Joule Black speakers which are awesome in all ways, but I wanted to hear the ATC 40’s. I think, if I was allowed to hear those speakers with MY amps, they would have produced even better sound. The farthest the speakers could be pulled out in the room (about 4-5 ft.), the better they sounded at the store. The wires they used were only long enough to go that far. I listened to many types of music that day and all who heard were impressed. Many of the employees came in to listen to them while I was there. It’s a big place with many rooms all over it.
