Curtains work on the highs, but they do nothing for the lows.

Depends how thick the curtains are. ;-)

Proper acoustic curtains which are usually hung in double pairs,
are *very* expensive.

My bedroom is almost square with one corner with an airing cupboard and the

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.

Egg trays will diffuse the top end fairly well, but they won't touch
what I was mainly aiming at - low frequency standing wave modes. You
can move around my listening room and the bass, I won't say it doesn't
change, but the changes are minimal. There are certainly no lost notes
anywhere

In our case for the 'hifi room'I used a rug which was bought for us as a
wedding present. It is (hand)made of a felt-like material. I hung it on the
wall from a curtain rail, spaced a few inches from the wall. Works quite
nicely and looks good.

Later on we bought a more conventional rug and used it in a similar way in
the living room. Also looks good and helps the acoustic.

I've done something along those lines, but I think you need quite a big
room to carry it off.

I'd also add that IME the speakers make a difference. I've found the
sealed box ATC I've been using for the past few years seem very unfussy
about placement, room and listening position. I've tried a few - ATC 7,
10s, 11s and now 19s. The 19s are overblown bass-wise if I turn up the
volume - but I don't do that too often. And the amp I'm using (a Quad
34/306) means I can dial it down a little if necessary.
