I made a post on SMD about the 2015 sheet so I'll share it here too :
"I've been developing the 2015 sheet for many months now.
For the most part; products that have changed in price have either already received updates / improvements -- or will be receiving them very soon. For example; the E v.2 series hasn't changed so the price is also exactly the same for 2015, the X-6.5 & X-8 are also the same, as are all amplifiers.
Pretty much across the board on everything else we've done a few things already; standard XL lead being a big one on the SD-2 & SA series. These also phased into the bigger subs earlier on last year. I am not aware of a single tinsel lead failure of the XL leads yet -- so it's a major upgrade.
Z v.4 went to standard US coils a while back & is getting an updated motor / higher RMS rating early this year. That is reflected in the 2015 price sheet.
X series will be going to a standard US coil for the v.2 & updated motor / higher RMS rating this year. The X v.1 pricing is actually staying the same until they sell out -- then the v.2 kicks in (SSA had put up the v.2 pricing by mistake). On that note... once we make the full shift any future drop-ins will also use the US coils.
And all new platform subs with Mega-Roll surrounds will be phasing into the Mega-Roll v.2 surround as soon as they come in stock.
So -- a ton of upgrades & changes as well.
