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!

That's good to hear. Was the packaging damaged on the amps when you received them?-Like somebody dropped it?
If you don't go the double box route, at least have him get some triple wall cardboard boxes. Those Home Depot double wall boxes are just too thin.
Also, if the amps are unwieldy (heavy/large), have him add strapping and/or corner bracing.
When manufacturers put 100lb items in thin cardboard, and expect UPS to move them gently, that is when problems happen. After all, if you are carrying boxes all day, the last thing you want is an unwieldy box.
That is why I like strapping. It give the delivery man a way to hold onto the box.

great call talking to RV

have to triple emphasize gdnrbob input on double boxing !
@gdnrbob - (why doesn't your handle ever show up when I type @?)  The box was intact, but could have been tossed about a bit without destroying the box, and there is no strapping or heavy corner guards.  That's why I offered to pay the difference for double boxing.  The amp is en route.  I will report back when it is returned to me.  If all goes well, I think a full review of the upgrade is in order.
@tomic601 - Turns out, RV was on vacation the week everything went wrong.  I had called Vandersteen Audio and got accurate answers to the questions I asked, but it wasn't the same as getting the complete story from The Man Himself.
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.
