I am looking to upgrade my L/C/F SuperSat 3's. There's nothing wrong with them but was wondering if upgrading would be worth the money. I also inquired about upgrading my FF4 sub and possibly going to the GE SuperSub as well with my local dealer but no response. So I purchased two of the SVS PC-2000 subs. I still wonder what 2 of the SuperSubs would sound like. I know they would definitely fit in my space better. Oh well, I have 60 days to try the SVS. Thanks in advance for your input.
