This leads me to a project I've considered for some time. Using a DSO I plan to capture and analyze (looking for clipping) the differential voltage at the speaker terminals while playing music and calibrated tone bursts.
Ascend has provided impedance plots for the RAAL Tower, which will help me to estimate true amplifier power at a given frequency.
I'll work my way up in successive volume levels until I reach either A) my normal listening level, or B) amplifier clipping.
Anything I should be wary of from a speaker perspective?
