That's great to hear that everyone is really enjoying their CLX's matched with subs to their liking. Afterall, enjoy what you're most happy with!
I was in the previous camp, where I didn't use subs at all for nearly 15 years. Our previous place was way too small for subs, even the bass drivers in the Ethos or Montis hybrids would cause our little apartment to shake! It was like being out at sea with a low level rumble that wasn't defined at all. When I had just got the CLX's then, it's bass panels were quite adequate in our little shoebox, so I didnt bother with subs. Fwd another 3 yrs since, and now, at our new place, this open plan space does require LF augmentation. The long hallway located towards the far right channel, acts like a wind tunnel, so pretty much all LF's tend to get sucked down this tunnel.
Although full range stats and other panel type speakers don't falter too much with side wall interaction, floors or ceilings, having a bit of side wall is still better than no side wall. So, I've managed to create a side wall just before the hall way starts, and this helps! Obviously the back wall / front wall is just as important for that dipole effect and the 10 millisecond delay... both crucial elements for dipole dispersion, as you all know. Finally locating the sub between the two stats dead centre, proved to be perfect in this particular room.
As I said before, if it was a much larger area then I would have considered two subs but this one is mighty fine! Plus the wifey is happy as... at least the system hasn't encroached the rest of the living space! Afterall, we must learn to share the space and appreciate what we can do with it, not make the audio system the centre of focus, although that has nearly been the case. So I'm not going to add anymore subs here.
Believe me, I've been to certain places where the audio system has taken over the entire living space, like an alien attack! The significant other basically has no say! I find this sort of arrangement very selfish and self centred. In which case, a dedicated room could have been established where that person can hibernate.
I know of this other case where the chap seemed to love the audio more than the Mrs... would spend exorbitant amounts on just about anything hifi related, even though it wasn't necessary. Constantly upgrading... to the point where their household debt went through the roof. One fine sunny afternoon, whiles he was away, she took a very large kitchen knife and cut deep into each of the Focal drivers. Then heavily damaged the cabinets and stomped all over the very highend tube preamp to pieces. Basically she didn't feel appreciated... and she walked out! That's all she wrote! Now this chap sits sadly in a one room apartment, with all his broken audio gear in storage. Some of it works and most of it doesn't. What a sad ending...
Obviously if you were single and had no other person/s to care for, then go nuts! As for me, I have other priorities and not just highend audio, although music is an important part of my life, yes.
At this stage, what I've put together, and having to start from scratch twice, since 2004, is damn good enough for me!
Cheers, and enjoy those fine tunes!
Woof! RJ
