The Porta Pack is a backpack designed to carry the original three-piece Cambridge SoundWorks speaker system. Mesh panels are positioned over each cone, and a flap provides access to connectors and controls.

The Porta Pack does make the SoundWorks transportable, although it lacks room for anything else. But the deal breaker is that far more portable alternatives exist at the price, and the once-revolutionary SoundWorks don't sound significantly better than travel speakers from companies such as Altec, Bose, and JBL.
