It mainly depends on how regulated the power supply is.
Or, could be the result of stressing the power supply enough to sag.
A completely unregulated power supply would result in a true 120x2 at 2 ohms, from an amp that was 60x2 at 4 ohms.
A very tightly regulated power supply could result in an amp that wasn't much higher than 60x2 even at 2 ohms.
With a power difference like this though, I don't suspect a regulated power supply, I suspect a
saturated (read: stressed) power supply.
I thought you were going to complain about RF's habit of publishing certain "rated" specs for their amps, then including birthsheets that admittedly don't conform to rated numbers (ie distortion spec ">" is circled

) with wild, way-up-there power numbers to make people feel like they got "a more powerful amp" than rated.
