Thanks Otto,

I actually brought home a Sunfire 10" sub from where I work last night to test it out. It does work and it does sound good.

The question I have for all of you 2 channel guys with a sub is....where do you place your sub? I connected the sub with 2 line levels from the preout on the amp to the line level in on the sub. The cables were only long enough to place the sub to the immediate left of the audio rack. I could tell the sound was a little off, meaning my towers have such good imaging, but I could tell that the low frequencies were slightly off the center axis.

Should I use 2 subs or place the sub on a side wall firing across the room? Also, I am planning on building a custom cabinet with 3 vertical sections. I could leave the bottom center section open to the floor and put the sub in the direct center of the 2 towers (front firing of course). What do you think about that idea?

What do you do?

Thanks, Mark
What main speakers are you using? As others have said, it sounds like you're crossing the sub at too high a frequency. Like most of us when starting out, you probably also have the sub level set too high. Did you try adjusting phase? I recommend a Radio Shack SPL meter so you can see what's happening. Well worth the investment.
