I am pretty sure the beta series is the more modern of the two. If you contact Infinity direct, using the phone numbers from their web site, the techs there will be glad to explain the differences in the two models, describing the drivers, crossovers, cabinetry etc.
I talked to them about the differences between the alpha series and the beta series. They were very helpful and straightforward. They can also direct you to a dealer with a showroom.
I live in NJ and the only easy place is Circuit City and they only have a limited supply of beta series and they have not been -for me- a good place to audition speakers.
Good Luck
