Morel MDM 55 2-1/8" Soft Dome Midrange
This Item is rated @ 200 watts RMS. Is this pre or post crossover?
I can't say for sure, but I highly suspect it is pre-crossover. Think about it this way: 200W is as much power as a high-powered incandescent lightbulb, which gets REALLY hot when in use. This midrange is about 3"x3"x3", which is a little bigger than a 200W incandescent bulb, so if it were fed 200W RMS then it would get about as hot as that bulb, which would surely melt the voice coil since a lightbulb's filament gets white-hot.Of course there are other factors to consider, such as the fact that you wouldn't feed 200W RMS for any more than a few seconds, even with the most intense music. Also, it will take a while for the metal of the midrange's body to heat up, which will delay the heating of the voice coil.But still, the fact remains that you must obey the laws of thermodynamics, and something as small as this midrange will not last long with 200W RMS applied to it. For a speaker of this physical size, I wouldn't apply more than about 30W RMS for more than a few seconds without worrying. So, this would correspond to about 150W musical power.
