heaudio123"No "sunshine", all the numbers show is that it can deliver 350 watts approx into 4 ohms with 1% distortion. Those numbers do not show output impedance which is what would actually jmpact frequency response"
As has already been sufficiently, properly, and correctly explained you are once again completely wrong even though you are partly correct but being partly correct is not fully correct. Output impedance is only one factor in this equation which you have sought to oversimplify by overlooking others factors as has been duly noted to you hear by others you’re pretending to be some kind of electronics/audio/acoustics "expert" suggests based on you’re own summation that you "perhaps" once worked for Radio Shack and are now qualified to call your self a "conskltant" even though you have such incomplete understanding of basic, rudimentary, fundamental elements involving audio and Music Reproduction Systems.
