ok I tried the nvx 2700.1 I think there is something wrong with it although it hits hard it not much harder than the nvx 1700.1 and gets much hotter
the 2700 fan is much slower probably the whole issue with the heat any way first thing I noticed was its near silent
the more these woofers break in the less I feel the need for it
I really am liking these tried to find a 3rd for an idea I had and the are back to $600 each choke beyond my budget
