I've heard that 8Ds from Elkhart, Indiana are better than those from the Abilene and Eastlake factories and are in general, very good horns. But, I'm slightly confused on which of the Elkhart horns are "the best." I've heard a lot about the N series, K series, the 900,000 horns, and the 300,000 horns. How do the other Elkhart horns compare to the more famous Elkhart series? Also, I've seen a lot of H series circulating on the Internet. How good are they compared to other Elkhart models?
