Hi WideOpen Throttle
I would advise ringing your country's Bose support number which you will find on the Home page of the Bose official site explaining, what you have been told, name of sales rep and store location + the extra purchase you have made reference the information you have been told.
Hope its good news for yourself.

That is great to hear! You are indeed able to connect two AM300's to the Lifestyle 650 with version 16.x. You can check the firmware version of the system using the instructions that Squadie had mentioned, or if your system is connected to your network and attached to a SoundTouch account, you can open the SoundTouch application>Menu>About>Lifestyle 650. That page should also list which firmware the system is running.
Thanks for the follow-up!

Yes you can certainly add another sub.
But the fun ends there.
Bose IS NOT EVEN future proofing the 650 by allowing upgrade to the HDMI 2.1 eARC for Atmos or DTS:X.
Yep! Spent $4000 on a system that will be obsolete in about 1 year. Just isn't that an exciting? A wasted investment of $4000. Way to go Bose. Thanks a million.
Wait . . . I mean thanks a $4000.
