Aurum Cantus Leisure 2 tweaks?

[Richard C]

Recently I been listening to a pair of Aurum Cantus Leisure 2's and whilst they do many things very well I constantly get the feeling that there is something missing from the sound.

I don't know whether it's partly due to the low efficiency but they just sound too polite and restrained. I feel I have to turn up the volume to liven up the sound, it like there's a potentially great speaker struggling to get out but it can't quite make it.

Has anyone else heard these speakers or attempted to improve them in any way? I haven't yet had the opportunity to delve inside the cabinets.
