I believe that you're listening to the difference in polar control at lower frequencies in the horizontal direction (assuming the EV horn is in a horizontal orientation), but maybe not so much in terms of "cutoff frequency" which is a function of the path length for exponential and hyperbolic horn profiles (but less so for conical and other straight-sided horns).
The Klipsch K-402 horn does the same thing. It's good down to 170 Hz based on 1/4 wavelength alone, but the biggest effect of the increased size of the horn is its control of polars with frequency. It's like night/day compared to its little brother, the K-510 horn, at lower midrange and mid-bass frequencies.
