The speaker sensitivity level comparison that carp has done seems pretty legit. 212 vs 215. Omnimic, receiver test tones, and spl meter. Two different speakers tested in the same room, same equipment, same process -same everything.
However the "just for fun" amplifier comparison LG to iNuke 6000 is impossible to compare in two different rooms with different source equipment etc.
I'm sure you guys know why - but just to make clear for those who might not -- -- - If you setup the 215HT's in two distinctly different places with auto calibration or test tones or what not - - - ---- IE - the Fox Theater in St. Louis, and the tiny HT of the month - the Hobbit theater or whatever - - - Reference level in the Fox Theater would still have 75dB test tones on an Onkyo receiver in a theater space that fits thousands. And it would have the same 75dB test tones after setup in the Hobbit theater. Both theaters would experience 'reference' level audio. And while reference in both theaters would measure the same SPL (assuming the 215HT could handle the Fox Theater) after calibration - they would NOT require the same amount of power to play reference.
On the smaller room to room scale - the analogy still applies --- you can't compare "X" above reference in two different places with different difficulties inherit to driving the sapce, different source equipment, different distances, different.......everything.
