Good to know you have the same speaker working well. I'm using Pulse Audio version 1.1. In the bluetooth log when the speaker is connected it reports "Bitpool: 2-53". I compiled the patch suggested here: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/424215/comments/34 I guess this would reduce the maximum bitpool by 20 but it didn't appear to make much difference.
