I think Kevin's nice procedure for testing it should still work in your case (from a post in the previous thread):

Here's the best way to test it:

1) Turn all of your speakers off.
2) Set all of your speakers as small in the 950. Sub on.
3) Find a bass intensive scene in your favorite DTS or DTS-ES disc. With either DTS or DTS-ES mode on the 950 selected, you should hear sound out of your sub. You might have to turn it up to hear it.
4) Now, change all of your speakers to large, sub on in the 950. Keep all of your speakers off.
5) Repeat #3. I bet you get LFE to the sub with DTS, but not DTS-ES.

You obviously have to be using the digital connection between your DVD player and the 950.


In your case, you could probably skip the "small speaker" approach and see if your sub gets a signal with the other speakers off. You will need to either disable the bass management in the ICBM or disconnect the pre-amp inputs from the full-range speakers (only have the LFE signal from the 950 going to the ICBM, so that it doesn't mix anything else in). It was pretty readily apparent when I tried it last week.
