[QUOTE="hispls, post: 8800779, member: 614752"] Again, I'm not really sold on Le being of any value in considering a high powered subwoofer. Dan Wiggins wrote a bit about the issue in a paper about cone speed but his discussion was involving a 6.5" midrange and 4000hz. I suspect low Le is more of an issue with full range drivers. I'm struggling to find the Le value for a well known underhung woofer with which we can compare to some coils I have on hand. The question becomes if the difference is only say 1/4 ohm at 100hz between a very small wind width underhung type coil and a beefy overhung, will there be any measurable or audible difference within the intended bandwidth? Can you dig up the numbers for anything you know of with a 3" coil? Be sure to specify which coil configuration they measure it. Do read the link to the audioholics damping factor discussion. The math shows that the difference between damping factor of 2000 and 10 is virtually nothing measurable and very probably not audible. [/QUOTE]
