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!

Hey Bob, I guess we can agree to disagree, right? The main thing is we both love Vandersteen. It's all good my friend.

I was looking for a Subwoofer for my Apogee Scintilla One Ohm speakers that would do justice to these top ends.  Based on the design, this forum and the recommendation of Johnny R, I have taken the plunge on a pair of Model 3 Subwoofers.  Should have them in about a month.  I was very impressed with the sound, and also the way that they are connected (HP filters) to minimally molest the top end, and the equalizer being analog in the base to equalize in most rooms.  I have any two corners that will pass the WAF test, so being confident that they will perform there was very big.  Johnny R really knows his stuff and is a pleasure to do biz with.  Thanks for the tip on this forum.  I will let you know how it all works out.
