[QUOTE="Haunz, post: 5080208, member: 576010"] You are in way over your head.... Fair enough.. and it's debatable.. but the more I think about it the more it's clear that the motor is integral to taking heat away from the coil.. Did you happen to catch the white paper that was being discussed on here a few months back which showed how ineffectual pole vents are at getting air to the voice coil and the top of the motor ? How many drivers only have pole vents, or no venting at all ? The question then is, where does the heat go ???? I am very confident in saying that if you took the same coil with the same amount of power it's going to run cooler and longer in a 100lb motor then it is going to in a 30lb motor.. Of course a 100lb motor is not always going to be practical or even necessary; and much depends on the application... As with any other aspect of a driver the sheer size of the motor is only one part of the overall equation... but it is certainly a part of that equation nonetheless... [/QUOTE]
