Just did the GR-Research upgrade on my center speaker. Sounds great now. More like I thought it would when I originally purchased it. It really needed the two inner speakers to be more of a mid-range driver. Took about 4 hours start to finish.

Just ordered the upgrade/fix for my RP-8000fs as well.
