Extension is about the same as the 'regular' Aurora, flat to 32-34hz.  But the Uber with the AudioTech Flex Unit do so with much more authority, with more tonal density.

Though I never actually heard the stock Auroras, I concur with the comments on authority and tonal density.  If I had to describe these speakers in a word it would be 'diesel' 

I'm really appreciating these things as they burn in.  I'll get some pictures posted shortly to show them off.

Did Ed make grills for your speakers?

He is in the process.  They are safe for the moment in my basement media room, but RMAF is the priority for now.  I'm sure he'll crank out afterwards.  He has a really unique material approach planned.
