The actual main issue is that you're assuming intermodulation distortions exist where they do not. I liked your comment just fine...need a hug?
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.
