I need speakers for low volume listening -

Have you considered headphones?

While there are many good suggestions here, for truly good lower level listening, you need either a speaker that will allow you to adjust the tweeter, midrange, and woofer levels, or you need a good quality equalizer.

This is due to Fletcher-Munson which cannot be ignored if you want quality listening at low levels. Highs and Bass will need a slight boost for the frequency response to be "heard" accurately.

Nearfield listening will also help, but not like adjusting the speaker, or quality equalization.

Zu Superflys - I had these in my home for several days and was very impressed with how well they were able to reproduce all of the music contained as well as the emotional expressiveness at low volume. (Driven with 6C33C SETs.)

BRF has the right idea. I presume you don't want to disturb your neighbors or new child. Real music is not soft...soft sections are contrasted with loud sections...even string quartets should be played at a realistic level....real music in real space is the goal of this hobby.
