Also Dayton audio has easy kits for first time builders (link on the bottom) If you are really up to it, you can build from scratch and save money!
There are instructions for proac response for example - google for them. You can build quality ones for a fraction of the msrp, and since you are an expert, you can make them look to your liking...
It's fun, but an involving project. If you get your feet wet and build one, you will save a lot of money in the long run no doubt...If I had your skill, I would attempt it in a second.
