Zenith Z434 hifi w/ dual cone speaker ?
 

Recently found one of these radios for $8.00, Zenith quit tubed hifi radios in 1967 and this solid state Z434 was the replacement in 1968. I'm looking for info on the "Dyna-Sound" speaker. Did Zenith use these in other radio's ? I had never heard of the "Dyna-Sound" speaker before finding this radio.

The radio has very nice sound, but not as good as the 8 tubed hifi units of the mid 60's (H845)

Can we see a pic? That may help a bunch. I too haven't heard of that speaker, but i'm not as well versed in the SS stuff.
