Please ignore my previous post; I was referring to this post: http://www.diyaudio.com/forums/head...lass-headamp-without-heat-18.html#post5032294
However, I misread it, thought it was an experiment with the headamp, but it appears to be a different project...

I do have an old tube headphone amplifier. (2W) Can they directly be used as speaker amplifier, or are there some aspects I'm missing?
Also, how is clipping limited or such small amps powering much stronger speakers? As I understood it, a strongly underpowered amp can quickly destroy a speaker by clipping.

I have measured it with a UMIK and REW (in the Dallas II) and I got >98dB/W/m in a 4x4m room.(It's rated at "only" 96 dB, BTW, but that still is fairly high for an 8" job.)
I'm not sure I understand this, could you please rephrase what you mean?Impedance response would seem to be lending itself to outputs with non-negligible output impedance so this may be worth experimenting with.
The gently rising impedance means it is very efficient because?
Thanks.
