High RE Value for SA12 D2?

Am looking at the T/S parameters for the SA-12 and noticed that the D2’s RE is listed as 4.33 Ohms when tested in series. From what I’m used to seeing, the RE values are typically less than the advertised impedance rating so the 4.33 feels a bit high for a sub with dual 2 ohm coils. The D4's RE value of 7.09 is right in line with what I'd expect. Could someone please help me understand what’s going on here with the D2? Thanks!
