The HTM200s match the sensitivity much more closely. It also seems like the SE tweeter will have an advantage in vertical dispersion over the Raals, but I'm very enticed by the all Raal surround system . This would be for home theater only, for music my source material is all stereo.
Your receiver will compensate for sensitivity differences between all the speakers. You room acoustics and distances will also affect overall output for each speaker at your listening position.

For most rooms, the surrounds are located quite a bit closer to the listener. For example, if your surrounds are 5 feet away from the listening position and the fronts are 9 feet away, these differences alone account for the 5.5dB difference in sensitivity.

However, there could be a concern if your surrounds are located at a further distance from the MLP than your fronts and your receiver does not have enough power.

Obvious question:

1. What is the distance from the listening position to the front L/R speakers?
2. What will be the distance from the listening position to the L/R surrounds?
