Vandersteen 2Wq subwoofers with M5-HP crossovers - help needed

I have been happily using a pair of Vandy 2Wq subs with single-ended M5-HP crossovers for a few years now. My system was dialed in the way I like it (bass a bit on the full side, but still tight and defined). I just had my amplifier repaired and upgraded, and the new input impedance is 22k ohms vs. the 10k ohms before the upgrade. I followed the Vandersteen recommendation for the jumper settings in the M5-HP (6 and 7 only, "on" or not open), and the bass is just about MIA altogether. As per the Vandy web site, I disregarded the chart on the case of the M5-HP and followed the chart on the web site.  Because I am an idiot, I didn’t bother to mark down the settings of the jumpers prior to changing them. Anybody have any suggestions for me that will restore the bass? I am pretty sure the issue is the jumper settings. Thanks in advance!

Great thread.  I learned the multimeter method from John Ruttan to setting my M5HPs.

i have a related question.  If a reading of .707 is the target with track 31 (80 has tone for 2WQ), would a reading above that (say .800) result in more or less bass?  Just curious.

I had a question related to setting the M5-HP boxes for use with high efficiency main speakers (97db).  The knob on the 2wq only goes to 94db.  (So when you turn up the volume, the main speakers get louder earlier than the subs.)  If you want more bass than the 94 dB setting allows, would you set them to the next lower impedance rating (for example, 50k to 30k) so that the multimeter reads 0.8xx instead of 0.7xx?
