The 175 is an awsome sub, I had one for a few weeks before I upgraded to my 500. My room was too small and the 175 kept bottoming out. The 500 is a monster sub. I have 1 and usually have to turn it down. At the time I was considering buying 2 175's. The reason for the 500 purchase was the DSP chip not available on the 175.
You will love the 175, i am sure. It shook my couch in my basment and the rest of the house. BTW, it was a really hard sale to my wife to upgrade to the 500 because of how great the 175 was. I still don't think she understands the reasoning for the upgrade.
You know when you have something you really like, and your going to upgrade for something better. Like a car or house. Even though you know the upgrade is a better solution, you don't want to loose the original. Thats how I felt about the 175.
Good Luck!!!
