My Magnepan speakers are 40"/50" from rear wall. i have drapes to sidees of widow, and tall shelving on side walls into corners behind speakers.
I had to move all the stuff away from the windows for a repair. So i started with the shelving i have (7 ft tall filled with DVDs) on both side walls tucked into corner behind speakers.
As I removed the DVDs the sound got significantly steelier.
After the repair, sticking the DVDs back intothe shelving brought the sound right back.
Interesting.

Many people start in the wrong place, buying magic wires, rocks and the like when they should be working on room treatments.
Wires, magic rocks and the like ARE room treatments, silly goose.
Next up, why CDs and LPs should always be stored vertically.
Unless you are a hot chick,than just throw them on the floor.
Maybe so they don't warp and you can access them? And when you try to grab one off the bottom the whole pile doesn't fall over and make a huge damaging mess?
had the tweeters outboard.

Records, I have found, are great diffusors. If you DVDs are fairly tightly packed, I suspect they would also be good diffusors.

Maybe a nice big 12X12 would work as well.:-)
That's not a diffuser. This is a diffuser.
Now, DVDs and CDs in their jewel cases are certainly resonators.

While shelves with DVDs on them certainly don't have the varied depth that the RPG has (which goes on the ceiling, BTW), or even the wooden RPG diffusors have, but a shelf, followed by an empty space back to the wall, followed by a row of DVDs, then another shelf, etc, would offer a hell of a lot more variation, hence diffusion, than a bare wall or a 12 x 12. Even a big plant can help if its got enough leaves.

Did you think of that all by yourself?

I agree with you.
I have a LOT of DVDs. I stuck all the normal ones into slimline cases. Only special DVDs wit ha thick pamphlet stayed in the original case.
So My DVDs are compressed to almost half the volume.
You might experience differences if they are less tightly packed together. Also do they go against the wall or stand forward of it? If the shelf is deeper than the cases, you might vary how far in or out they are.
The best diffusors I have heard were 4 by 8 feet and with varied depth in the 1 inch wide slots.
I cover my CD racks with fleece blankets. There are four in the room and they affect the sound for the worse. They are on the same wall as the speakers with one inside and the others outside the speakers.
I have a Squeezebox now so they'll likely go away when I rip all my CD's. That will probably take close to a year at the rate I'm going.

I have records on Ikea shelves behind my speakers. It helped the sound quite a bit when I put them in.

racks make really good diffusers ! even better than CD cases...
I second your use

Had to sell my Martin-Logan Quests - could never get them to sound right in my concrete and glass echo chamber
Maggies are dipoles, of course the rear corners would be very critical to sound.
