Ironically, some speakers require more efficient amps that deliver more current to sound right at lower volumes. If the amp can do that and can deliver enough current (not same as watts), and the speakers can also handle high volumes without break-up or distortion, then the system can go loud as well.
Get the amp AND speaks right to play at low and high volumes and you are golden.
Amps that double power or at least come close to doubling from 8 to 4 and then from 4 to 2 ohms will in general be able to drive more speakers well at lower volumes.
Examples of affordable amps that can do this are various models from Musical Fidelity over the years and many newer Class D amps.
Examples of speakers that will not sound as good at low volumes without proper amplification (lots of current) are Dynaudio, Totem B&W and OHM.
Triangles and Magnepans do well at low volumes with most any amp in my experience. Maggies are less efficient though and also require lots of power to go loud and clean.
Triangles sound great at low volume with most any good amp and are more efficient and can go loud as well with less power, which makes them them the most versatile I have owned in terms of sounding great all the time, in most any room, with almost any amp.
