Default PR Calcs

Am I doing this correctly? Could somebody please check my calcs. I have calculated a conventional SBB4 alignment to produce a Vb of .7ft^3, Fb=33Hz, and F-3=32Hz. My driver has such a large Vd ports are impractical for this alignment. I have assumed two 10 inch passive radiators are adequate each with an effective diameter of 8.125 inches. I have determined each radiator must weigh 292 grams. Is this correct? Does this make sense in an applied perspective?
