If you have an active crossover then the tweeter amp can be rather
lower powered. In theory you could get full power out of a CD at any
frequency but in practice the levels drop at higher frequencies.
An experiment on your favourite music with an audio editor such as
Goldwave will be helpful. Split it into three at your chosen
crossover frequencies and search for the maximum level in each file.
This will show the relative voltage and hence power required for each
amp, assuming all drivers have the same sensitivity.


Interesting. Is Goldwave a freebie?

You can download an evaluation version.

I tried splitting a track (Money, from the CD layer of the DSotM SACD)
at 300Hz and 3000Hz.
The peak voltages we
Low 0.96
Med 1.00
High 0.82 (surprisingly high)

So you could use a couple of Cyrus Twos and a Cyrus one for the treble
but it would be better to use three identical amps.


Won't my T27s freak out if there's a 50W amp dedicated to them?

You could use a capacitor in series with the T27, as long as you
factor it into the active crossover response.
