I am having some trouble getting any bass from this sub. I have it hooked up to a pioneer 1014TX. I have Polks RT-1000p fronts, Polk 245 center, and Polk M Series for surround. I have the crossover on receiver set to 80 and the sub have it turned all the way up. I know something is wrong with the setup. I went to bestbuy and they had a cheap sub on display and I can clearly hear the bass. I have DVE and have calibrated just using the test tones. Is there a setting on the receiver I am missing? Room is upstairs. Dont have exact dimensions but its a little smaller than a 2 car garage, with 2 doors in the back.
