I now understand why David Dicks chose AN Alnico 15" than AN Neo 15" for competiton with high end speakers, cause Alnico has an excellent mids and low frequency, superb 3D soundstage and details that can rival most high end speakers.
The Neo on the other hand esp the 8." Is ideal for critical listening or for studio monitor. It is an all around music genre fullrange speakers. The Alnico is best in vocals/opera, jazz, blues music. I hope this will help you in choosing between Neo and Alnico.
