We have used a flexible geometry model of a calorimeter design for SDC to study the effect of passive material in front of the calorimeter and between the barrel and endcap modules on the apparent response to hadrons. The thicknesses of the passive materials have been chosen to closely resemble the currently projected wall thicknesses of the scintillating tile-fiber and liquid-argon calorimeter designs. The liquid-argon model contains about three times the amount of material in its shells compared to the tile-fiber model. The solenoid coil reduces the relative difference somewhat in the barrel region but constitutes only a minor correction in the transition region from barrel to endcap. Correspondingly, we find a significantly worse response for the liquid-argon case which we demonstrate using beams of single {pi}{sup minus} particles of 10 GeV/c momentum. 13 refs., 6 figs.
