Being a latecomer, I have the benefit of the earlier postings.
Sdcampbell, Gboren are right to the point with reading the specs and the importance of interpreting +/- 2 or 3dB. I understand that genuine spec ratings are recorded with some sort of standard reference equipment, sensor mounted 1m on axis infront of the speaker driven with some standard frequency sweep signals, in an anechoic chamber. So there is some standard measurement in the speaker manufacturing industry.
Red I love the climax of your soprano story! The room size resonance effect in our real listening area does distort the overall sound that we perceive, and resonance must be controlled with every practical means possible.
My own experience is that there is vast difference in bass reproduction between my M.Logan Aerius (45Hz +/-3dB) and my later acquired Dynaudio A72 (28 +/-3dB) despite what some of the above posts opined. With the exact same gear I had been using, the Dyns came out with so much ooomph(body)and deep sound staging, a big step closer to like "being there" feeling compared to the Aerius. All along I thought Aerius'45Hz is low enough for reproducing whatever in the CD; I was wrong!
I believe that when our ear response starts to roll off at some point, the guts (feeling) takes over down to even lower frequencies.
