Planars like Magnepan are fantastic at low volume. full range electrostatic speakers like the Quads also.
Box/dynamic designs that use rigid low mass materials (like paper) for woofer cones can be similarly very good also. Triangle is the line that comes to mind as an example.
I find the newer OHM Walsh speakers I also use can also be similarly quite good in a different way at low volume with the right amp and electronics in front of them, and these can also go as loud as needed with no signs of stress or dynamic compression as well with proper amplification, which is a big reason I prefer these over most planars or electrostats in the same price range.
