Found this:You really need the speaker impedance curve to understand the power requirements and a brief web search didn't bring one up. My guess from the limited info we have (i.e. 200-800W amp required) is that this speaker has a cruel phase angle curve which means that at some frequencies more power might be dissipated by the output devices in the amp than what ends up in the drivers.
Take sensitivity with a pinch of salt as it may only be measured at one frequency and the manufactures don't give the necessary info to make it meaningful.

"
The MB2 is a claimed 90 dB/Wm efficient and
presents a very fair eight Ohm load, dipping only to
5.9 Ohms at 110 Hz."
Which would imply that as long as there aren't any nasty phase angles going on, it's a relatively moderate load.
As a comparable, my own speakers (not PMC) drop to very close to 4 ohms in a couple of places and there wasn't a hint of flabby or uncontrolled bass (to my ear) with an Arcam SA20 amp, which isn't a high current design and puts out 90W/ch
