I was told it was more powerful than a steep ro powermax

What , the cub ?
Whoever told you that wouldn't be able to produce data to support it .
The powermax uses the weaker 1200w motors @350 airwatts each
so 700 airwatts total for two , the single 6.6 has 646 airwatts .
Two regular 1400w lamb three stages would have 900 airwatts .
