EDIT - I was away all last week. Didn't see Roadranger had a post on it already. I googled before I posted and didn't see anything anywhere else. Well, at least you can get the MAP pricing.
I don't see it on the JBL site, but RMC Audio Direct just sent me an email and has the full line up listed HERE.
The claim is better cooling and "same light weight"... Well the weight is up substantially from the 600 series so I'm not sure where that statement comes from. For instance, at 42 lbs, the 12" cabinet is up 8 lbs (over 20%) from the 600 series and is 2 lbs heavier the 500 series. This makes sense as they use ferrite magnets. The 18" XLF subwoofer though, is practically the same weight at 81.5 lbs, up just a half lb.
Of note there is a 10" full range option as well as "XLF" 15" and 18" subwoofers and no "S" version sub. All good moves, IMO.
