515 GHP has the lowest Qts(.187) and highest efficiency(8.6%) of any of the 515's making it the ultimate horn driver, and ideal for use in a bass/mid-bass horn. It's stiff suspension and high power handling will allow it to play VERY loud for extended periods.
The 416 is more ideally suited for loading in a large BR box with it's more compliant suspension and significant low frequency extension. Understanding it's acoustic and electrical limitations will be important factors in it's longevity in any application where a 515 GHP would also be used.

not a bad price. but still not cheap. plus i would have two pair if i got around to building 210s.
i do like the sound of the 416s. and they do go fairly low. i'm guessing i will definately need a sub with the 515 HPs in my 828s.
