You have already gotten some good suggestions, but I thought I might add to the discussion. First, no AVR you buy is going to EQ the subs separately. XT-32 with SubEQ, for instance, is only going to allow separate SPL and distance settings for dual subs. They will still be EQed as one. The .1 LFE channel is a single channel and that is the way that all AVR's are supposed to work.
The suggestion to try different room placements is a good one. Audyssey is doing what it can, but the better condition you present it with, the better job it can do. There are two other things you can try. One involves Audyssey, and the other involves your subs. First, with respect to Audyssey, you can try either turning off DEQ, or using an RLO setting to mitigate it's effects, because it is boosting your subs by 2.2db for every 5db you are below Reference. At -15 MV, for instance, DEQ adds 6.6db of sub boost. As you experiment with the RLO settings, you might find a sweet spot that let's you enjoy the content you want without the port chuffing. And, you can change RLO settings on the fly, during a movie.
The other thing you can do is to use the 20Hz port mode on your Pluses. Doing so will necessitate re-running Audyssey, and this isn't something that you can easily change back-and-forth. But, it will probably eliminate the port chuffing entirely, while still giving you good bass down to about 20Hz. If you do it, don't forget to change the DSP setting in the subs as well as with the port plugs.
That gives you two measures you can use--one more permanent in nature, and the other transient, depending on the particular material you are watching.
