[QUOTE="Remotia, post: 1769454, member: 568127"] Pretty much! The W7's bl graph still tailed off quite a bit when i measured it on the Klippel. The Eclipse (and Soundsplinter for that matter) Linear motor(s) works by using a variable density voice coil to fill in the missing force by using a lot more wire near the extremities of the coil. So when it moves up and down, you don't get this parabolic Bl over displacement graph. You pretty much get a line from xmax to xmin. As far as box recommendations, go by what Eclipse says, and as far as how loud these subwoofers go? They have a linear xmax of 25mm and can be pushed to a 3" stroke. Yes they will get pretty darn loud. Power recommendations. 1500 watts RMS into a sealed box is not out of the question for this driver. Here is a photo of a new Eclipse linear coil (left) next to a non linear coil (right) Note that the wire sizes are different and so are the former heights, just ignor that, I couldnt find two equal looking coils but I think you get the point ;p [IMG]http://www.bpbackup.com/linear.jpg[/IMG] hope that helped [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [/QUOTE]
