Poor Audio Quality on 12" PB via Bluetooth

On my 12" PB 1.5GHz I notice real poor audio quality over Bluetooth. The BT speaker works fine on my MBP, iPhone 5 and other recent Macs. I've even noticed the same problem with the sound being choppy on my 1.33GHz iBook too.

Are these Macs just too old? Does BT audio take up too much cpu power?? Anyone else have experience with this?
