I clearly stated that I measured the speakers with the Bose EQ on. That is the only way you listen to the speaker so it would be kind of pointless to measure them without it. You don't measure speakers w/o their crossover, do you? Try it and see how long your tweeter lasts! Of course the response of the 901 will drop in the bass and treble without EQ. I suppose I could measure them without just for comparison purposes. Then, you could clearly see what the EQ is doing, and what the amp is doing.
My friend, to whom I sold my first pair of 901's, bought a Bose receiver to drive them with. If memory serves, it was rated at 40W/channel. Due to the high mid-band sensitivity of the Series III thru Series VI 901, even low powered amps can drive them to very satisfying levels. I use a 200W/channel Adcom, which happens to have little LED's that are supposed to light when distortion reaches a certain level (1%, I think). I've never seen them flash on, ever. I almost always listen in a darkened room, so I should be able to see them since the amp is at the front of the room. And I like to listen at around 90-95dB peak-level. Rarely, when the wife and kids are away, I have gone beyond that level with rock music. Still no distortion indicators. And the amp never gets more than barely warm, so the 901's are an easy load, even a life-like levels.
One thing you brainiacs may not be factoring into my measurements is room gain and speaker coupling at the lowest frequencies. I measured both speakers at the same time.
To whoever posted the picture of the anechoic chamber: What was that supposed to prove? That was not a living environment. That was...an anechoic chamber. My point still stands -most people don't listen to music in those, we listen in real living spaces with lots of hard, reflective surfaces.
You have probably run taichi4 off, but I hope not. I appreciate his posting of the link to the Australian magazine's test. I will read the whole thing when I have time. taichi4 is reasonable and respectful, traits some others here would be well-served to emulate.
