These will work too

I am a little surprised that the frequency response isn't a little better
though. I would expect them to go up to 16 kHz or 20 kHz before cut off.
They still get the sound but it is at least 3 db down from the sound in the
frequency response band.
BTW, I am having trouble seeing the circuit diagram you refferenced. maybeif
you could direct me to it from the maplins home page

It must have to load something soI can see it.
