JA>         my statement that power capabilities of an amp (the more the 
 JA>         better) having to do with better control of the speaker and 
 JA>         its' mechanics, beyond its indication/ability of volume levels, 
 JA>         I will have to stick by this also. However, beyond a certain 
 JA>         point, power capabilities ONLY give bragging rights and offer 
 JA>         nothing more to the control of the speaker. This cut off level 
 JA>         will depend largely on the speaker themselves, their quality 
 JA>         and sensitivity. I am sorry it has taken so long to get back to
 Amp output impedance, speaker input impedance, and total
 speaker mechanical impedances produce the damping factors
 quite apart from other factors mentioned.  If x volts of back
 emf plus mechanical factors of x are present and equal, a 10 w
 amp is the same as a 100 w amp or 1000 w amp.
