Difference in sensitivity between full lambda and 1/4 lambda horn design?

High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

216.184.97.165

Let's say a LF/MR horn built according to 1/4 wavelength length and mouth area giving say 105 dB/watt and then a full wavelength horn using the same driver. How much of a difference in sensitivity increase can you expect?
I know that doubling cabs will get to 108dB and then doubling again will get to 111dB/watt. Mouth area with four cabs will equal full lambda horn mouth area but have only 1/4 wavelength in horn length compared with full lambda size horn. What would the actual (predicted) sensitivity be in the full lambda size horn compared to 1/4 size horn?
