Yes RTanything is rather worthless in small rooms. True.

What you are looking for is decay slope. You see the decay response of your treated room is very much better in the mid-rang and high, but there is still a long tail to the decay of the LF.

Of course it is caused by modal ringing, and I would suggest more bass trapping and maybe a little less absorption in the mids and highs to balance the decay. Your room then will not be so 'dead'. You could also add some diffusion elements to help the room sound larger and more natural.

Dead rooms really are not the best - they are only the best that some can do with given their circumstances.

Here is an interesting little paper I have just finished on the topic of modal decay. - comments are welcomed.

Cheers,
