Hi Jim,
There were several changes, the 3.1 includes:
- the tweeter adjustment switch was removed. Gallo found few people used it, and the switch was easily broken when you took the grills on/off. Upside, a more pure signal path.
- new/different midrange drivers. The new midrange drivers are identifiable by looking closely at the outer edge of the driver, if it has a prononced lip it is the new midrange.
- minor change to the crossover. I think they changed a few capacitors.
Gallo made these changes before they announced the 3.1 If the speakers were made after September 2005 chances are they are the 3.1, you can email or call Gallo with the serial numbers and they can confirm.
Although I heard the original model 3 many times and ended up buying a new pair of 3.1's I can't really say if you'd be better off buying new or not. They are wonderful speakers and a terrific value at their price point. Jeff
