Glad to see it's not me going mad then.
Interestingly, I found you can fix the problem by adding an aperiodic vent to the cabinet (just model the same 160ltr cabinet with 2 x 4" ports, but with a leak). Would be interesting to hear how that compares to a smaller cabinet. As you say though, it has a large peak in the group delay, so perhaps the smaller cabinet is the best way to go.
I've not tried that, trouble with leaks is their unpredictability in a practical/ executional sense.
