The subwoofer you have should do just fine but before running Audyssey make sure you have you subwoofer placed where you want it. If you have leeway in placing it, try the following.
http://www.axiomaudio.com/tips_subwoofer_placement.htmlAs Randy (sirquack) said turn up the crossover on the sub to 150 if that’s the highest setting. Your receiver should auto detect what speakers channels are hooked up if not make sure to tell it you now have a subwoofer hooked up in the setup menu. Then run the auto calibration and Audyssey on your receiver. As Randy said the receiver will try to make settings based on what it’s detecting.
I have a Denon 2807 and find that the performance of the autocal/Audyssey on it are very room and speaker location dependent. So it may get things just right or could be way off so at least review the settings it made and if for example it sets a small speaker that doesn’t go very low to “large” you should probably change it to small and 80Hz as Randy suggests.
From here it doesn’t hurt to use a test disk and SPL meter if you have them to verify the settings. But if you’re like many of us those settings will go out the window when you start tweaking everything to fit your personal tastes.
Cheers,
Dean
