Not quite. You first need to know what you are treating for. Slapping up room treatments without knowing is not a good idea. That is not to say that some treatment isn't done right off the bat. However, before you do "tuning" treaments, you need to deal with timing first and foremost...which Audyssey does. Personally, I would treat the room afterwards if needed. Treatment is not cheap by any means either if you want it to look nice. With my room, some treatment was necessary, but not for tuning per say the frequency response. I didn't need bass trapping at all, and I used a minimum of absorption. It's really all about design and placement folks. Audyssey and treatment only provide the polish so to speak. This is why I say, you don't need to keep upgrading if the room was done right from the beginning. But, I will say this, timing is everything as well, and my room really does sound great once I polished it with Pro. I still get shivers up my spine everytime I listen to my system. It really is quite magical. But nothing is greater than the whole. Every part of the room integrates well, and each aspect played a significant role in the final outcome.
