Hello, I am putting together a 5.1 setup for my family room. The room is 17x22 with a ceiling that slopes from 8-11 feet. The back of the room is completely open, connecting to my kitchen/dining area, which is a total space of about 12x22 with an 8 foot ceiling. I had a local audio guy in to take a look, and told him my budget for the whole system. For the subwoofer, he recommended a Sunfire HRS-8 for $650. My suspicion is that he is recommending this unit because of his markup more so than it's merits as a sub. I know that many on this forum have strong feelings about Sunfire subs, so I figured that I would ask for other recommendations on this forum. Can anybody recommend a better sub in this price range ($600-$700) for the size of the room that I described? It will be used mostly for home theater, but some music. Thanks! Jon
