Lloyd,
The first question in my mind re: actively low cutting your main speaker at 38hz is: What's your program material?
If this is a music-centric system, I'd only point out that very few recordings in my collection have much signal below 38hz. We're talking about a couple of keys on a piano, the longest pipe on an organ, and a couple of notes on the electric bass, for the most part. It's pretty rare that these are present on a recording so the low-cut isn't really doing much to lighten the load on your X-1s 99+% of the time.
Obviously movie soundtracks are another story, but your set-up appears to be 2 channel, so I'm guessing that it's music based. I personally don't see a ton of benefit in crossing a sub in so low on a music system, but many other knowledgeable folks (including, evidently David Wilson) disagree with me on that one.
Rhyno,
I was just trying to clarify a few points that you made in a little different way, because they seemed to me to be presented in the way JL deems best to promote their (admittedly excellent) products. I hope I made clear that I wasn't really taking much issue with the main points in your post, more clarifying in a way that I feel is more even-handed. As you say, however, it's mostly six of one, a half dozen of the other.
