What do you mean as a ‘main driver’? 

We’ve been through this discussion several times since product introduction. Have you read through any of these discussions?

Hi Bruce. By "main driver" I mean the largest forward facing driver in the Era 300 speaker. This driver is disengaged by the software when the speaker is used as a surround speaker in a home theater configuration. It makes sense to some extent for movies, but last I heard there is still no option to turn it on when playing music which is a serious flaw in the software. We want to use the Era 300 to its full capability when playing music. 

Hi Buzz. Yes; I was part of the initial discussions and have read many since. I am still wondering if Sonos has made or is planning to make a software update to allow us to use the Era 300's to their full capability when playing music. As we all know, the speaker itself has the capability. We just need a toggle or something in the app to allow users the freedom to use it. Ridiculous if Sonos is still dragging their feet on this one. 

I think we’ll need to wait until the developers work through all of the hanging details associated with implementing the “new improved” controllers are worked out before a final determination on implementing this sort of detail will be made.
