All these filter settings were what REW calculated based on the room measurement, so that's how I set them up. But I agree that they are a bit weird. 9dB of gain just 4Hz away from 5.4dB of cut does seem pretty strange.
I have tried removing filter 2 and slightly reducing the amount of attenuation on the neighbouring filters - we'll see how that goes. I'm beginning to wonder if I'm in danger of getting trapped in a cycle of fiddling around trying to find the best compromise. Having to keep swapping between HiFiBerryOS to set up the filters and piCorePlayer to properly audition the results is a pain in the rear. Just listening to music would be a better use of my time. At the moment, the low level bass grumbling caused by the DSP room correction is more annoying than the lumpy response of the room. Wouldn't surprise me if I end up removing the DSP card completely and just accepting the bass nodes in the room!
