I'm no expert, but this doesn't sound like a cabinet issue. Speakers don't get blown at low volume and speakers don't stop interacting with the signal from the head - unless you have a loose wire. Check the wires running to the speaker.
Some amplifiers have built in protection that makes them cut off temporarily when they overheat. This can be due to blocking a vent or running the ohms too low. So it's entirely possible when you hooked up your head to another cab this had had time to restore - or the other cab had a better match with ohms. Were you running any other speaker cabs with the Eden that would cause the ohms to drop? Have you tried any other head with the speaker cab or the same head later?
