Yes indeed Bob, 
	That is exactly what I meant about using a modern replacement.  Those 8 inch coaxial speakers will far out perform the old 12" speaker.  There was at one time some nice 12" coaxial speakers around but I don't see them anymore except in ovals for cars.  But, again, a guy could build a mounting plate adapter, are use the grill, to make these fit into the old cabinet, and have a very nice speaker system.

As far as great sound at low levels, there are a number of computer speaker sets made by Altec Lansing, Bose, and others that will just blow you away for under $50.00. They have power ratings that are very inflated in most cases, but they still sound great.  

Now for ham radio listening with QRM and noise, I prefer a narrower bandwidth speaker.  I have some small 4 inch speakers in little wooden boxes, which can hardly be called HIFI.  I can put one right in front of my face and it is a lot like headphone presence.

The Devil is the culprit of old age I'm sure.  Don't believe in all that golden years stuff.

That is great John but look at the freq response
of that speaker...Great low end but only goes to 4
K on the high side... Some of these SW Stations
are going out to 12 and 15 K...Great for AM
Amateur Voice use..Check out this 8 inch at
... It goes out to 16K and cost is $18.
Wholesale...Pro Net is $32...Take off the grill
and transformer...The tranny is great as a 500 ohm
to 8 ohm conversion. Throw the grill away  LOL...
Like I said to Brian use a pair of these and they
will rock from a push pull amp or even a single
ended amp...
