I finally added a second REL Sub

It's taken me years to get to this point.  Subwoofers were 2-channel system blasphemy when I was coming up in the hobby.  As of today, I now have 2, REL T9is.  They are providing sub-bass and filling out the picture for Klipsch Cornwall IVs.  Even with a loudspeaker as massive and efficient as the Cornwall IV, they fill things out nicely.  

How pleasing it was to hear the two in unison.  I run them so low on crossover and volume that the only thing you hear is sweeter more extended highs against a fuller picture down low.  They are simply not audible in their own right.  Yes, it's true--good sub bass management helps treble and midrange.  

As a hack musician of 20 years or so, I can tune them by ear when I hear a well recorded kick drum, bass guitar and horns.  I tried tuning with mics and software but the good ol' ear does very well here.  

If you're on the fence about one or maybe a second you owe it to yourself to try it.  Is SWARM next? Doubtful.  This is, however, very pleasing indeed.

Yes two subs is great for every system. Best upgrade I ever made. 
Something you should try is high passing them. I 100% sure you will get better sound, as in much better. Crossing them over higher (40hz-70hz, I use 60hz,). This is not a low pass but a crossover to the mains and it will take your system up another level. 
The subs simply outperform your speakers under 80hz. At 60hz the drivers in your main speakers start to fall off and struggle. This also will take a lot of vibration out of the main boxes abs let the mids do their thing. 
There are a few options from JL and bryston for active crossovers. Something like a mini dsp might be a cheap way to try it if your preamps does not support it and the JL-CR1 is too pricy.
