If the density is too low, then the lower frequencies won't even know that it's there. The higher frequencies will be diffused and the lower frequencies will do what they were doing before the diffuser.

You might just want to get a football helmet for your drummer....though on second though, they are pretty pricey....maybe not.

update: i found some info.. the foam in question is 1.60 pcf .. much shy of the recommended 2.8 pcf. ... what problems can i expect?.. i am ok with some absorption.. i have some flutter i would like to get rid of.

At 1.6 pcf, I think the diffuser will reach down to about 1 Khz....maybe a hair lower. It will get rid of flutter. A little here and there would probably help. I wouldn't use too much of it in a room though, because of the limited bandwidth.
