I should clarify my earlier comments. I have never owned a Tentec 307, but I
have a generalized prejudice that radio manufacturers sell speakers at a
premium because the cosmetics of the speaker match the rigs. Any Icom speaker I
have ever purchased was overpriced garbage - unfortunately. Perhaps the 307 is
different, but I am willing to bet that most of the money is because it says
Ten Tec on it. The Sound Sweet speakers are a LOT MORE speaker for the money
compared to any radio manufacturer speaker I have owned - but again I have not
owned a 307.
