Do you adjust your subwoofer


I have kef reference 3 speakers and a rel 510 subwoofer 

 I keep the  crossover low and the volume low as well. It gives just a little extra down low

I was wondering if people bump up the subwoofer when using it for movies, just for the extra thrill

Also, this makes me think that having stereo subs might be better warranted if I do the aforementioned changes...

You bet. IMHO 1 sub is a waste of time. I tell people to hold off until they can get two. No matter where you put one sub in a room you are going to get very lumpy bass as you move about the room and it will change with frequency. Within 6 feet you can go from too much bass to no bass. Two subs smooths this out and the more subs you add the smoother the response gets. I just went from four 12" drivers to eight 12" drivers. The larger the surface area used for low bass the lower the distortion, Getting down to 18 Hz flat is not easy. It requires a lot of driver and surface area. My system is up 6 dB at 20 Hz. It returns to 0 dB at 100 Hz. This gives the effect of a live performance at less than tinnitus inducing levels.

I use one sub in my room and it has worked fine for me. But again I use acoustic software that has RTA, phase , and coherence. If you are listening in one spot only, one should not do much adjustment unless you trying to fill an area that requires more area to fill like for HT where their is more then one person in the room then I can see your point in using an array configuration.

Where I have a small listening space, I have found that the small sub I have right now centered in front of my amp-stand sounds pretty seam-less with my stereo speakers.  I do want to send the full-range speakers just the upper-bass and up, which I'll experiment with in the near future...  Thanks again for your help on this !

I have similar controls for my subwoofer and I've found that my single sub in my small listening space it seems good.  I'm not sure at this point I need a second sub.  Thanks !
