I've done the software update this week and have no issues with the base altering from how it was before and I can say that the difference in sound when adding the base speaker is amazing. I am having issues with the base speaker loosing connectivity with the soundbar though as I've mentioned in another post which bugs the hell out of me.

You can buy the acoustimass300 without any problems it's very good and very powerfull, The only thing is that the latest updates are not perfect and Bose should listen to us to fine tune the sound quality.

Add me to the list, no issues here with the latest update. I did run the Adaptiq after the last update. After I'd installeed the update, things sounded different. Things are good here.
Edit: So I did some testing today and have to agree. The thunder is gone. The sub is working and it's pushing out some level of bass, but not what it once was nor what I expect from it. I get that downgrading is an option, but frankly that's a hassle I don't want to deal with unless I'm going to be stuck with this for an extended period of time.
The AM 300, when working as intended, is an absolutely wonderful addition to your ST 300. Once I heard it, I knew I had to buy both pieces together.

Personnaly, I'm facing the same issue as many others since the last firmware update. Bass level has decreased significantly....
Now, there's no real difference in sound with Accoustimass on or off

Hi Old Greg, PatR171, and GMAD,
We've seen a few reports similar to this one and we're looking into it. We do know that an AdaptIQ bug that impacted many systems was actually resolved in this version and our theory is that it's connected somehow. We've got a call into engineering and we're doing some in house testing to try to recreate the issue. In the meantime, we'd suggest following THIS thread because it'll be difficult for us to keep track of many different ones. We'll provide updates there today at some point.
