I have a 7000 system setup in my home theater with a projector. I am mostly happy with the setup, except the center channel is pretty weak. even if I turn up the center in the configuration it is still somehow difficult to hear the dialog. 

The fronts are BL1 and the center is a smaller JBL speaker. I use the same JBL speaker in another (dolby digital) setup in the basement and it seems to be fine there, so it must be somehow related to the AV7000 or the fact it is prologic.

As this is a projector based setup and most of the components are non-beo, I dot want to spend the money on a BS3. Any ideas are appreciated.
