RE: Tri-amping T IV-A's with tubes?

Roger, are you sure about this: "The peak power for higher frequencies is almost as high as for the bass"??

For example, at PS Audio's web page it is said that "It takes a ton of energy to reproduce bass notes, but not a great deal as the scale goes upwards. Fact is, most tweeters never see more than a few watts."

Here are two examples:
Michael Jackson - Don't stop til you get enough, the upper curve

Michael Ruff - Wishing Well, orange below 100 Hz, blue above 100 Hz

  Thanks again Roger, but I don't have a clue what these images should tell me regarding the tweeter's power needs? :-)

    " My advice is still to have similar power on basses and mid/tweeter " ... I would agree.
    
    I used (ss amps):
    * 180w into 4 ohms on the bass panels
    * and 120w into 4 ohms on the mids & ribbons (3ohm ribbons).

    The one on top, shows the same level from bass to tweeter.
    
    The second one, shows a higher power demand for frequencies above 100 than below, 3 times more.
    
    These are peak level not average. Musik is peak level, not sinus.
    
    My advice is still to have similar power on basses and mid/tweeter.
