Am I going to kick myself? I had a CS 20-39 and a s700 combo. I sold that and I ordered a CS 20-39+ and a s1000. I talked my wife into this because it is only $100 more than the previous combo. Now I was thinking........ Darn for only $250 more I could have two 20-39+ subs because then I would qualify for the 20% off discount. Do I really need this? My room is 20x18 with 12 foot ceilings. One side of the room opens up to the dining room and the other side opens up the the kitchen. Thanks for you opinion.
