How about going with the reference series bookshelves instead? You could get the RB-51 and RC-52, matched with a good sub it will sound just as good at the larger towers. The Klipsch reference series is much better than the Synergy line, I would definitely wait and save up for that. With the money saved from going with bookshelves instead, put that towards a better sub.
