Guys, the problem you run with adding subs in any system is integration of the subs. It's VERY VERY hard to get subs that share the same sound as the main speaker. This is one thing that Vandersteen was able to do. I know many of you have subs and love them etc... and that's cool. I"m not trying to rain on your parade. I you go read how Vandersteen does the crossover adn how his amp is able to pick up the same sonic character as the main amps, then you will understand what I'm saying. I too felt the Focal's bass was good, but very limited, especially in this price range. Many think I'm married to Vandy's, but it's MY money and I want what I personally like best, so I went with the Quatro's as I didn't' hear anything under 20k (and more) that I liked nearly as much overall. I play a ton of old rock and there is plenty of bass, plus it's tunable as I've said before. That's so important in most rooms. It's not the digital Turing either, that does negatively affect the sound if you listen closely. I felt the set up was easy. The dealer came over to do that part. The PRoac would also be my second choice.
