Got it. Like I said, since my currently three sets of Sierras are a mix of originals and upgrades, I couldn't remember what was what.

Now, starting with the LX, as described in this thread, we are including a full range anechoic on-axis measurement that is accurate down to 20Hz. This is printed but we do store the data so it wouldn't be difficult to provide a text file of the response if someone wanted the data to plug into an EQ. It is a bit time consuming on our end to provide this, so we would have to charge a small fee for it, likely $20-$25 or so - but yes, can easily provide this.
That would be great! Sign me up for that with my LXs—I haven't gotten a shipping notice yet so hopefully there's still time.
