It has this middle sounding honk no matter what speakers I use. Short of
coating all the walls with old cardboard egg boxes I wondered if these new
miracle speakers from Sonos might help, or is this room auto compensation
stuff just hype as to me it seems that if there is a resonance you won't
stop that no matter how you adjust speaker frequency response.

Egg boxes never did anything,

The legendary Gooseberry Studio in Soho had a drum room with walls
and ceiling lined with egg boxes, or rather egg trays - the larger
square ones. It worked pretty well.

but if you have a spare duvet - hang
that on a wall.

Indeed. You can get effective sound treatment from Ikea at a very
reasonable price. If you want it to look good too, the duvet can
have a solid wood surround (for example a frame about 10cms larger
that the duvet made from old floorboards, sanded. varnished and
mounted edge-on to the wall. The duvet can be suspended within the
frame mounted corner to corner with transparent fishing line. It looks pretty good.
