I *did* once connect an old 12" 25 watt speaker of no useful value to a 100 watt amp to conduct a similar test also when bored. The result was quite smoky but absent of flames. In the early days of high power sound reinforcement in the UK a certain brand of amplifiers was popular since they were about the only model made in the UK and available at a sensible price unlike US models. Their internal cooling was 'optimistic' to say the least and it was popular for these to 'go DC'. Such failures were indeed known to cause some spectacular speaker fires. Graham
