<VV> 30 watt or 80 watt replacement speakers

[hallgrenn at aol.com]

I'm with Matt and Frank on the speakers.  The AM radio's amplifier is not exactly high fidelity to begin with.  In very general terms (no flame please) the higher powerhandling capacity of the speaker (80 watts versus 30 watts) implies less efficiency (it needs more power for a given sound level) due to a larger diameter voice coil, differenct cone surround and other design features.  The radio's amp can only provide so much power at a given distortion level--at higher power levels the distortion curve goes up drastically.  So if you connect a higher efficency speaker (usually, but not always) the one with the lower power handling rating then you are more likely to get a higher volume at a lower distortion level.  In my early Corvair days I sold high fidelity equipment at two different companies.  The company that sold the cheaper equipment used to keep a good pair of AR speakers for comparison to their high markup cheaper speakers.  Connecting the low efficiency (but high quality) AR speakers to their cheap, low power amps resulted in distorted sound because the cheap amp couldn't produce enough power at low distortion and was driven into "clipping" trying to power the ARs while the same amp connected to the cheaper, higher efficiency speakers produced a much better sound.  We sold few AR speakers there, but lots of cheap, high markup ones (I left as soon as I could afford to).  

Sort of like the scene in "Ruthless People" when the salesman demonstrates the really big speakers to the naive buyer with the pregnant wife.

Not only is 10 watts all you have in a stock radio, you also only have ONE
hannel, mono. So why two speakers mounted in one opening? In case you
pgrade later to a stereo radio?

I am going to replace the stock speaker in my '65 sedan (without a/c) and
ave 
ead as much about it as I could find.  The consensus seems to be that the
wo 
mall speaker setup as offered by one of the vendors has a good sound and
s 
robably what I will buy.  My question is this:  with a stock a.m. radio
and fm 
onverter) will the 30 watt version be sufficient or should I reach really
eep 
n the piggy bank for the 80 watt?   I don't plan on blasting the radio or
n 
rying to break all the spot welds in the car with it.Does anyone have the
0 
att version installed that can make a recommendation?  Or recommend
nother 
peaker?Jim
