Default Horrible Bluetooth lag.

Ok everyone. I'm experiencing horrible lag and dropout with a Bluetooth speaker box. I'm on CM10.2 Android 4.3.1. I understand this was a known issue in 4.2 JB can anyone confirm this is an inherent and unfixed issue? If so I'm terribly disappointed. I'd like to be able to use the Bluetooth speaker. Seems like this should be a priority for Google. Any solutions or ROMs where this is fixed?
