Subwoofer output closer or farther away from wall

With a sub you should not really be aware of its output unless you turn it off, if you catch my drift. I doubt it is output. Those are the same subs on the Infinity Prelude and Intermezzo 4.1's. Did not the sub come with a RABOS kit? This kit will allow you, with a little patience and difficult reading allow you to set the volume and parametric EQ. Like I said I have one of the suckers attached to each speaker and rarely do I know they are working unless I forget to turn them on, and they are almost flat in response to 23 Hz in my room. Maybe you are missing the "boom" of regular speakers? If you have the kit and need some help explaining how it works shoot me an email and I'll help.

Never had just one turned on as they are set up that way with the RABOS system. But the volume is only about 3 1/2 on each and my room is about 25 * 13 with cathedral ceilings. Got rid of that nasty 47 Hz hump I'll say that. The only other subs I ever had around were an earlier Infinity Il120 (I think hat was it) and the B&W 2000. I'll stick with what I have, if that means anything.

And since you asked I’ll go ahead and say that I did not think the subs worked properly both at first and until I measured them. I was not prepared for a smooth bass response. Others also say two subs is best but I'm not exactly convinced of that.
