RL906 nearfields? The 1" tweeter, 5" woofer very nearfield monitor?
How small was/is this room?

To put 22 RL906 in a room would mean you'd have to bass manage all of them because they aren't close to Dolby spec (and less so at a distance) and you couldn't even get 22 within their designed listening distance of 1m.

I don't think you are getting a good impression of any of these formats with such a limited frequency response speaker. If this is for research, then you've already faltered on this bit.
