Something that I don't have to crack the volume for it come alive.
Perhaps I should consider horns?
But, I didn't think they would be a me a good match for my electronics (Spectral)
You should consider whatever sounds best to you, regardless of whether horn, direct radiator, panel, etc.
At low volume. That's not a terribly difficult scenario to recreate demo wise, at home, dealer, show, etc.
Not sure what model Spectral, but you most likely have far more than enough power to recreate low volumes, regardless of speaker type and sensitivity.
Your ears, like every other human (regardless of beliefs), follows equal loudness contours, which means you hear things differently at low volumes, vs mid or high volumes. What audiophiles often seek, since they shun things like tone and worse, "loudness" controls (which were once popular when common sense prevailed), are speakers with built in loudness curves.
I.e., tilted up bass and treble native response. That will definitely sound better at low volume! Maybe not so much at mid-high. YMMV.
Side note, I've exhibited dozens of audio shows, meets, etc.
I'd guesstimate 1 in 1000 audiophile attendee actually bring their own tracks to listen and evaluate systems (including loudspeakers) with. These are the very same folks asking questions like yours here.
Somehow they are able to determine certain attributes when there are 50+ variables, unfamiliar equipment, connections, power, sources, rooms, etc, etc....with unfamiliar tracks.
IOW, the one constant/reference: how particular very familiar tracks sound to you at home, say at low volume, on ones own system, are
not used, in totally unfamiliar environment evals. Go figure.
Good luck with your search.
cheers,
