Hello,

I?m searching for another pair of Duplex speakers and am overwhelmed with the choices. I currently have a pair of 904?s with 515HP cones and 909 drivers.

I?d like to get my next set by buying less than perfect ones, probably much older models, since they seem to be more available, and getting them reconed and new diaphragms.

Does anyone know of a spec sheet(s) that lists many/most of them, any opinions on your favorite kinds? Any comments on cabinet sizes and porting?

Thanks again,
Jack
