CSS just posted some info over on the MAC DIY forum on their SDX15 subwoofer they are planning on bringing back. This looks like it could be a monster if the Klippel data they posted is real. Might have to add this to my short list of subwoofers for when I convert my basement into my HT room.

Impressive, the XBL2 motor design seems to be working well as the magnet isn't even that big for such excursion capability. Wonder if it can do 100hrs at +/-30mm without the glues failing though.
I doubt many woofers can actually do this but in home use it's not like it would ever see that anyway unless you like listening to 20 Hz tones 24/7 😛
Apparently B&C woofers are rated for xvar for that number of hours:
