^ I've measured them and I found if anything to have higher sensitivity and output than Jeff rated them. Others have concurred.
So how much output do the M2's have from 20-80hz, I am really curious? It all may be a moot point since they have what you need for SPL and the other attributes are key to the experience, but since we are talking output I thought you might know.
