The M1's have amazing bass. They love power and are fairly inefficient. If I'm correct, they are 83db at 1 watt and run 6 ohms and they drop to 4 ohms. Why don't you try bi-amping these?
Also, keep in mind that a speaker's wattage rating doesn't mean what you think. Rating them at 220 watts is a suggested power rating for your amp. But, 1 watt of distortion could blow them much more easily than 400 clean watts of music. Overdriving your GAS could kill them.
