Subwoofer output closer or farther away from wall

I pushed the subwoofer closer to the wall, and the improvement of the low end in comparison to the previous set up is not small. Now, I can feel, I guess hear it being more active than before. The other question that I have Kchahoc, you have the same subs, right? Was there a different between having two instead of a single one? I wonder. They are on sale now, but I wonder, if I will be able to hear an improvement should I get a second one, or I will overbassing my listening room. How is this sub in comparison to others you have heard?

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.

I am very confused with the manual set up of the Rabos system. At first when I was doing the level of the system, I could not get the system to go to 0 db as stated in the manual, the closest I could get was 1 db. So, now that I pushed it to the wall, I am sure I will get more output. The questions I have are several.

First, how did you manage to get to 0 db as stated? I had to crank my main horn speakers and and the sub to get it to 1 db, should the output be calculated, flatly with the sound output of the sub? I got my volume control to about 11 o'clock to get the 1 db. That is question 1.

Second, when I began the measurement of the width, I as a smooth plot at 1 db from 100 hz to about 60 hz and from then on, there were variations. For whatever it was worth, I had a hump or peak at 45 hzFrom there on, I read the scale and began to measure the gradations, attempting to get the W, L, Fr at the peak hump to be as flat as possible to 1 db level. Is what I did right?

The manual is very bad in explaining the set up, so I had to interpolate information to get all the information and also, to deductively adjust the sub. I will have to re run the test now that I have placed it closer to the wall.

I would like to have some answers to the inquiries that I have.

Thanks.
