<VV> Replacement radio speaker options - late model

[Roger Gault]

Les,
One more thought.
I would NOT put a resistor in series with a 4 ohm speaker.  Besides eating
an average of 60% of your output power,  and making the system pretty quiet,
it will make the system non-linear, since the impedance of the speaker
varies with frequency.  These kind of things are very offensive to us
engineer types.  Whether it makes any difference to someone who's been
listening to the stock "speaker" for all these years is a different
question.  ;-)

Roger
