So it will be mostly a cosmetic + name upgrade then. Considering they already use the Ultra driver and amp, the sub deserves the name.
Which brings me to the topic... if the SB13-Plus only had side panels veneer... what exactly is the (probably maple or natural-oak colored) sub displayed on the front page of sonicboomaudio? Looks to me like a full veneer sealed sub... Was that a prototype? An early version of the SB13-Plus? Or an older sub altogether? Maybe I should just ask Mason directly by email.
EDIT: I managed to link to the image directly:
