I know this might be more appropriate in the batteries section, but... Is there that big of a difference in the internal resistance of a dry cell battery compared to a regular acid battery? thanks.

There are two kinds of impedance in batteries, the impedance due to the mechanical components, and the "chemical" impedance. Since the regular lead acid and sealed versions (dry and gel cells) differ in both respects it is hard to say which is better. Regular lead acid normally uses large plates or grids, great for the mechanical component. Sealed lead acid batteries typically use a spiral wound, or jelly roll construction which would have a higher impedance. Chemically I think the edge goes to the sealed cells, they have more surface area on the positive and negative plates due to the spiral construction, and are typically very good at pulse discharges like you would see when starting a car or burping a SPL system.

I would think that the sealed batteries would have an edge in an SPL setup. But if the difference would even be measurable on a meter I can't say.
