Most coherent low volume speaker with very fast bass under 10k used?

I have the Rockport Aviors and I find them very coherent. They play particularly well at low SPLs. However, I my view, they need good quality, high current amplification to bring out the best in them, especially at low volumes. As such, I second the view that you should focus as much on amplification proposed to be used as much as the speakers - the two are not mutually exclusive....in my view
